Minor Children and Guardianship in Wills Australia: Complete Guide 2025

Complete guide to appointing guardians for minor children in Australian wills. Learn guardianship requirements, testamentary trusts, financial arrangements, and state-specific rules for NSW, VIC, QLD, plus all states.

Quick Answer

To protect minor children in your will, appoint a guardian, structure how their inheritance is managed, and align your other nominations. Guardian appointments are recommendations, courts decide based on children's best interests, but usually follow parents' wishes.

  • Appoint a guardian: Name a primary guardian and an alternate who shares your values and is willing to raise your children.
  • Create a testamentary trust: Manage the inheritance until children are mature enough (18, 21, or 25).
  • Separate guardian and trustee: Consider splitting these roles for checks and balances.
  • Align super and insurance: Coordinate beneficiary nominations with your will.

Providing for minor children is often the primary reason parents create a will. Without a will, a court decides who raises your children and how their inheritance is managed, potentially not the people or arrangements you would choose.

This article is part of WillBuddy's Knowledge Centre covering guardianship and provision for minor children in Australian wills. We explain how to appoint guardians, structure financial protection, and ensure your children are cared for according to your wishes.

The Australian Context: Why This Matters

Statistics That Highlight the Importance

Statistic Implication
59% of Australians don't have a valid will Most children are unprotected
5.1 million dependent children in Australia Millions of children need guardian provisions
1 in 5 families are single-parent households Guardian appointment even more critical
Average age of first-time parents: 31.7 Parents still have decades of dependency to plan for
65%+ of parents worry about who would raise their children Yet many don't formalise wishes
Average cost of raising a child to 18: $250,000+ Financial planning essential

The Reality of Not Having a Plan

Every year, Australian courts must decide guardianship for children whose parents died without a will. These cases involve:

  • Competing claims from multiple family members
  • Children placed with people parents might not have chosen
  • Family disputes that can last years
  • Children separated from siblings
  • Significant legal costs depleting children's inheritance
  • Traumatic uncertainty during already devastating circumstances

One family's story: After both parents died in a car accident in regional Victoria, the maternal and paternal grandparents fought for custody of three children. The court case took 18 months, cost over $80,000 in legal fees (from the children's inheritance), and resulted in the children being split between households, something neither parent would have wanted. A simple guardian nomination in a will could have prevented this entirely.

Understanding Guardian Appointments

Key point

A guardian appointment in your will is a nomination, not a binding appointment. The court makes the final decision based on the best interests of the child, but it gives significant weight to your wishes.

What Is a Guardian?

A guardian is the person you nominate to raise your children if both parents die before the children reach 18. The guardian takes on day-to-day parental responsibilities including:

  • Where the children live
  • Education decisions
  • Healthcare decisions
  • Religious and cultural upbringing
  • General welfare and wellbeing
  • Day-to-day discipline and guidance
  • Extracurricular activities and social life

The Legal Framework

Guardian appointments in Australia operate within a specific legal framework that parents need to understand.

Aspect Details
Legal status Nomination, not binding appointment
Who decides Court makes final decision
Weight given Courts give significant weight to parents' wishes
Override possible Court can appoint someone else if in child's best interests
Who can nominate Both parents should nominate (ideally the same person)
When effective Only if both parents die (or surviving parent is incapable)
Legal principle "Best interests of the child" paramount

How Courts Make Guardian Decisions

When courts consider your guardian nomination, they assess:

Factor Court's Consideration
Parents' expressed wishes Strong weight given to will nominations
Child's wishes Considered for older children (typically 12+)
Existing relationships Bond between child and proposed guardian
Guardian's capability Physical, emotional, and financial capacity
Stability Disruption to child's life (school, friends, location)
Siblings Preference to keep siblings together
Cultural and religious factors Continuity of upbringing
Any concerns History of violence, substance abuse, or instability

The Surviving Parent Usually Becomes Guardian

Important: If you die and your children's other parent is alive and capable, they automatically have guardianship rights, regardless of your will's nomination.

Situation Who Has Guardianship
Both parents alive Both parents jointly
One parent dies Surviving parent automatically
Both parents die Court appoints (considering will nomination)
Surviving parent incapable Court may appoint nominated guardian
Parents divorced Surviving parent (unless court orders otherwise)
Estranged parent Still has rights unless legally removed

When Your Nomination Matters Most

Your guardian nomination becomes crucial in these scenarios:

Scenario Outcome
Both parents die together Your nomination guides the court
Single parent dies Your nomination is primary consideration
Surviving parent later dies Your joint nomination applies
Surviving parent becomes incapable Your nomination may be used
Surviving parent is unfit Your nomination becomes alternative

Choosing the Right Guardian

Key Considerations

Selecting a guardian is one of the most important decisions you'll make. Consider these factors carefully:

Factor Why It Matters Questions to Ask
Values alignment Will they raise children as you would? Do they share your views on education, discipline, religion?
Willingness Have they agreed to take on this responsibility? Are they genuinely willing, not just obligated?
Capability Can they handle the practical demands? Do they have the time, space, and energy?
Age and health Will they be able to care for children long-term? Will they remain capable for 10-18+ years?
Location Will children need to move? Change schools? How disruptive would the change be?
Existing children Can they handle more children in their household? How would their children feel?
Financial stability Can they support additional children? Can they provide adequate care?
Relationship with children Do your children know and trust them? Would children feel comfortable?
Emotional stability Can they handle grieving children? Have they dealt with loss themselves?
Parenting style Is it compatible with yours? Would your children thrive with them?

Questions to Ask Potential Guardians

Before nominating someone, have an honest conversation about:

  • Are they willing to be guardian if the situation arises?
  • Do they understand what's involved, the commitment, the challenges?
  • How would they approach key decisions (education, religion, discipline)?
  • Where would children live? Would they need to move or renovate?
  • How do their own children/partner feel about it?
  • What support would they need (financial, practical, emotional)?
  • Are there any circumstances where they couldn't serve?
  • What are their views on maintaining relationships with other family?
  • How would they handle teenagers differently from young children?
  • Are they willing to follow your documented wishes?

Evaluating Common Guardian Choices

Potential Guardian Pros Cons Best For
Your parents Close bond, experience raising children, often retired with time May be elderly, less energy, health concerns Young children, when grandparents are fit and active
Your siblings Similar age, share family values, may have similar-aged children Own family commitments, may live far away When siblings are established and willing
Close friends Know your parenting style, chosen family May not have legal family connection, may fade When friends are stable and deeply committed
Children's godparents Already accepted ceremonial responsibility May be symbolic role only, may not be willing When godparents were chosen for this reason
Aunts/uncles Family connection, may know children well May have own commitments, relationship varies When there's a genuine close relationship
Professional guardian Impartial, experienced No emotional bond, expensive, institutional Very complex situations only

Age-Specific Considerations for Guardian Choice

Children's Ages Special Considerations
Infants (0-2) Need guardian experienced with babies, intensive care, sleepless nights
Toddlers (3-5) High energy required, need childcare/preschool arrangements
Primary school (6-12) School stability important, homework help, activities
Teenagers (13-17) Need guardian who can handle adolescence, boundaries, independence
Mixed ages Guardian must handle multiple developmental stages

Real Family Scenario: Choosing Between Options

The Chen Family: Sarah and Michael have two children aged 4 and 7. Their options:

Option Assessment
Sarah's parents (ages 68, 70) Adore the children, retired, available. But health concerns, father had heart attack last year. Would need to raise children for 11-14 years.
Michael's sister (age 42) Close relationship, two children similar ages, stable. But lives in Perth (family in Sydney). Children would need to change schools, leave friends.
Best friend couple Know the family well, no children of their own, stable careers. But never parented before, travel frequently for work.

Their decision: Nominated Michael's sister as primary guardian (best balance of capability and commitment), Sarah's parents as alternates (for short-term if needed, with plan to transition to sister). Included wishes about maintaining relationship with Sydney grandparents.

Appointing Alternate Guardians

Always appoint at least one alternate (ideally two) in case your first choice:

  • Dies before you
  • Becomes incapable due to health issues
  • Is unwilling when the time comes
  • Is deemed unsuitable by the court
  • Has circumstances that have changed (divorce, relocation, financial problems)
  • Has their own family crisis

Recommendation: Create a hierarchy of alternates:

  1. Primary: Your first choice
  2. First alternate: If primary is unavailable
  3. Second alternate: Backup to the backup
  4. General direction: "If none of the above, I request a member of my extended family rather than my spouse's family" (or similar guidance)

How to Word Guardian Appointments

Basic Guardian Clause

"I appoint [Full Name] of [Address] to be the guardian of any of my children who are under the age of 18 at the date of my death. If [Full Name] is unable or unwilling to act, or has predeceased me, I appoint [Alternate Full Name] of [Address] to be guardian."

Joint Guardians

You can appoint joint guardians (e.g., a couple):

"I appoint [Name 1] and [Name 2] of [Address] to be the joint guardians of my minor children. If either is unable or unwilling to act, the other shall act as sole guardian."

With Multiple Alternates

"I appoint [Primary Name] of [Address] to be the guardian of my minor children. If [Primary Name] is unable or unwilling to act, I appoint [Alternate 1 Name] of [Address]. If [Alternate 1 Name] is also unable or unwilling to act, I appoint [Alternate 2 Name] of [Address]."

With Specific Wishes

"I appoint [Full Name] as guardian and express my wish that: (a) My children continue to attend [School Name] or a school of similar quality and approach; (b) My children maintain regular contact with their maternal/paternal grandparents and extended family; (c) My children be raised in awareness of the [Religion/Culture] faith and traditions; (d) My children's inheritance be used for their benefit and not absorbed into general household expenses. These wishes are not legally binding but are an expression of my hopes for my children's upbringing."

For Separated Parents

"I appoint [Guardian Name] of [Address] as guardian of my children if their other parent, [Ex-Partner Name], predeceases me or is unable or unwilling to care for them. I make this appointment in the belief that [Guardian Name] will best serve my children's interests and maintain the values and approach to parenting I have established."

Testamentary Trusts for Children

Key point

Without a trust, children receive their inheritance outright at 18. A testamentary trust lets you set a later vesting age, control how funds are used, and provide asset protection and tax benefits until your children are mature enough to manage the money.

Why You Need a Trust

Without a trust, children receive their inheritance at 18, the age of legal adulthood in Australia. This can be highly problematic:

Issue Consequence Real-World Impact
18 may be too young Large sums at 18 can be mismanaged Average 18-year-old lacks financial maturity
No spending guidance Money may be wasted on non-essentials Cars, parties, "investments" in friends' schemes
Vulnerable to others Partners, friends may exploit young adult Manipulative relationships targeting inheritance
Tax inefficient Direct inheritance taxed at adult rates Lost tax benefits worth thousands
No asset protection Exposed to creditors, divorce Future spouse may claim half in divorce
Mental health issues May fund destructive behaviour Addiction, gambling, poor mental health

Case Study: The $400,000 Inheritance

Jack received $400,000 at 18 when his father died. Within three years:

  • Bought a $65,000 sports car (depreciated to $35,000)
  • "Invested" $50,000 with a friend's failed business
  • Spent $80,000 on travel and lifestyle
  • Lent $30,000 to friends (never repaid)
  • Lost $40,000 to gambling
  • Remaining $135,000 spent on rent and living expenses

At 23, Jack had nothing left. A testamentary trust with a 25-year vesting age would have protected him and potentially changed his life trajectory.

How Testamentary Trusts Work

Element Details
Created by Your will
Comes into effect When you die
Managed by Trustee you appoint
Beneficiaries Your children
Vesting age Age you specify (18, 21, 25, 30, or staged)
Until vesting Trustee uses funds for children's benefit
After vesting Funds distributed to children directly
Tax status Separate taxpayer with special benefits for minors

What Trusts Can Pay For

The trustee can typically pay for:

Category Examples Typical Costs
Education School fees, uniforms, books, tutoring, university, TAFE, vocational training $15,000-$45,000/year
Healthcare Medical, dental, optical, therapy, medication, mental health Variable
Housing Rent contribution, bond, furniture, utilities $15,000-$30,000/year
Living expenses Food, clothing, transport, phone $12,000-$20,000/year
Activities Sports, music, hobbies, school trips, camps $2,000-$10,000/year
Special needs Disability support, special equipment, therapy Variable
Capital items Computer for study, car when appropriate, work tools As needed
Life events Wedding contribution, home deposit assistance As appropriate
Emergency funds Unexpected medical, legal, or financial needs As needed

Choosing a Vesting Age

Age Considerations Best For
18 Legal adulthood; may be too young for large sums Very small inheritances only
21 Traditional choice; some additional maturity Smaller inheritances, mature children
25 Greater life experience; career often established Medium inheritances, most families
30 Maximum maturity; may be too restrictive Large inheritances, concerns about maturity
Staged Portions at different ages Large inheritances, balanced approach
Never (lifetime trust) Remains in trust for life Special needs, very large estates

Sample Staged Distribution Structures

Conservative Approach:

"The Trustee shall distribute to each child:

  • 25% of their trust fund when they attain age 25
  • A further 25% when they attain age 28
  • The remainder when they attain age 30"

Balanced Approach:

"The Trustee shall distribute to each child:

  • 10% of their trust fund when they attain age 21
  • 30% when they attain age 25
  • 30% when they attain age 28
  • The remainder when they attain age 30"

Education-Focused Approach:

"The Trustee shall distribute to each child:

  • Sufficient funds for tertiary education between ages 18-25
  • A home deposit (maximum $150,000) when they demonstrate readiness to purchase
  • The remainder when they attain age 30"

Milestone-Based Approach:

"The Trustee may, at their discretion, distribute portions of the trust fund when the beneficiary:

  • Completes a tertiary qualification
  • Maintains steady employment for 2+ years
  • Demonstrates financial responsibility through savings
  • Purchases a first home"

Tax Benefits of Testamentary Trusts

Benefit Explanation Example
Adult tax rates for minors Income distributed to minors taxed at adult rates (not penalty rates) Child receives $18,200 tax-free instead of $416
Tax-free threshold Each child can receive up to $18,200 tax-free Family with 3 children: $54,600 tax-free
Income splitting Income can be distributed among family members Trustee distributes to lowest-taxed beneficiaries
Flexibility Trustee can manage distributions for tax efficiency Vary distributions year-to-year based on circumstances
CGT benefits Capital gains can be distributed strategically Distribute gains to beneficiary with capital losses

Worked Example: The Smith children's testamentary trust earns $30,000 in a year from investments. With three minor beneficiaries:

  • Each child is allocated $10,000
  • Each pays $0 tax (under $18,200 threshold)
  • Total family tax: $0

Without the trust, if the same income flowed to one adult:

  • $30,000 taxed at marginal rate
  • Approximate tax: $4,742

Annual benefit: $4,742 saved in tax

Choosing a Trustee

Who Can Be Trustee?

Option Suitable For Pros Cons
Individual (family) Most common, often family member Personal interest, no fees May lack expertise, potential conflicts
Joint trustees Provides checks and balances Dual oversight, shared burden May disagree, slower decisions
Professional trustee Complex estates, ongoing management Expert management, impartial Fees (0.5-1.5%/year), less personal
Public Trustee Affordable option for simpler situations Government-backed, affordable Less flexible, bureaucratic
Combination Balance of personal and professional Flexibility, expertise Complexity

Guardian vs Trustee: Same or Different?

Approach Advantages Disadvantages Best For
Same person Simple; one point of contact, faster decisions No checks on spending, potential for misuse Small estates, completely trusted individuals
Different people Trustee ensures proper use of funds, accountability May create conflict, slower processes Significant estates, any concerns about guardian
Professional trustee Expert management, impartial, proper accounting Fees; less personal, may not understand family needs Very large or complex estates

Recommendation: For inheritances over $200,000, strongly consider separating the roles. The trustee provides oversight to ensure funds are used for children's benefit, not absorbed into the guardian's household expenses.

Real Scenario: Why Separation Matters

The Morrison children were left $350,000 to be managed by their guardian uncle. Within 5 years:

  • Uncle "borrowed" $80,000 for his failing business
  • Household expenses were charged to the trust without clear records
  • When children asked for university funds, little remained
  • Legal action to recover funds cost $45,000 and damaged family relationships

With a separate trustee, every payment would have been documented, large withdrawals would have required justification, and the uncle couldn't have accessed funds for personal use.

Trustee Duties

Duty Details Practical Meaning
Act in beneficiaries' interests Children's welfare comes first Every decision must prioritise children
Invest prudently Manage funds responsibly Balanced portfolio, appropriate risk
Keep records Maintain accounts of all transactions Annual statements, receipts, justifications
Avoid conflicts Don't benefit personally Can't use trust funds for own purposes
Distribute appropriately Apply funds for children's needs Regular payments for legitimate expenses
Account to beneficiaries Provide information when requested Transparency about trust assets and spending
Act impartially Fair treatment if multiple beneficiaries Don't favour one child over another
Follow trust terms Comply with your wishes as stated Can't deviate from will's directions

Trustee Fees

Trustee Type Typical Fees
Family member Usually none (may gift small amount)
Professional trustee company 0.5% - 1.5% of assets per year
Public Trustee 0.5% - 1.1% of assets per year (varies by state)
Lawyer acting as trustee Hourly rates ($300-$600/hour) or percentage

Example: On a $500,000 trust:

  • Family trustee: $0/year
  • Professional trustee at 1%: $5,000/year
  • Over 10 years: $50,000+ difference

Financial Support for Guardians

Why Guardians Need Financial Support

Raising additional children costs money. The average cost of raising a child in Australia is $250,000+ from birth to 18. Without provision:

  • Guardian may struggle financially
  • Your children may feel like a burden
  • Guardian may need to spend their own savings
  • Quality of care may be compromised
  • Guardian may decline the role due to financial concerns
  • Children may miss opportunities (better schools, activities, travel)

The True Costs of Taking on Children

Category Estimated Annual Cost Notes
Housing adjustment $10,000-$50,000 one-time Bigger car, renovation, furniture
School fees (private) $15,000-$45,000 Per child per year
School fees (public) $1,000-$3,000 Fees, uniforms, supplies
Healthcare $1,500-$3,000 Not covered by Medicare
Food $5,000-$8,000 Per child per year
Clothing $1,500-$3,000 Per child per year
Activities $2,000-$6,000 Sports, music, hobbies
Transport $2,000-$5,000 School runs, activities
Holidays $2,000-$5,000 Additional family member
Childcare (if needed) $10,000-$25,000 Before/after school, holidays

Total: $30,000-$100,000+ per child per year depending on lifestyle and school choice.

How to Provide for Guardians

Method Details Recommended Amount
Initial setup payment Lump sum for immediate adjustment costs $20,000-$50,000
Trust distributions Trustee pays guardian for children's expenses As needed, receipted
Housing provision Contribution to larger home or renovation Market-dependent
Regular payments Fixed amount per month/year for basic care $1,000-$2,000/month per child
Reimbursement Guardian claims documented expenses from trust As incurred
School fee payment Trust pays school directly Full fees

Sample Guardian Support Clauses

Basic Support:

"I direct my Trustees to pay to the guardian of my children: (a) An initial sum of $30,000 to assist with any necessary adjustments to their living arrangements; and (b) Such sums from the children's trust fund as the Trustees consider appropriate for the maintenance, education, and welfare of my children."

Detailed Support:

"I direct my Trustees to provide financial support to my children's guardian as follows: (a) An initial establishment payment of $50,000 within 60 days of my death; (b) A monthly care payment of $2,000 per child, adjusted annually for CPI; (c) All school fees, uniforms, and educational expenses paid directly to the school; (d) All medical, dental, and therapeutic expenses on presentation of receipts; (e) Reasonable holiday and recreational expenses up to $5,000 per child per year; (f) Any other expenses the Trustees consider reasonable for the children's welfare."

With Accountability:

"The guardian shall provide the Trustees with quarterly statements of expenses claimed, and the Trustees shall have access to records of how funds have been used for the children's benefit. The Trustees may reduce or suspend payments if they believe funds are not being used appropriately for the children."

Superannuation and Life Insurance

Super Doesn't Automatically Go to Children

Superannuation is not controlled by your will. It's paid according to:

  1. Your binding death benefit nomination, or
  2. The super fund trustee's discretion (if no binding nomination)
Nomination Type Effect Duration
Binding nomination Must be followed by fund Usually 3 years
Non-binding nomination Fund considers but decides Ongoing
Non-lapsing binding Must be followed, doesn't expire Until changed
No nomination Fund decides (usually to dependants or estate) N/A

Important: Without a binding nomination to your estate, super may:

  • Go directly to adult beneficiaries (bypassing your trust)
  • Go to your children at 18 (bypassing your trust)
  • Be contested by multiple dependants
  • Be distributed in ways you wouldn't choose

Coordinating Super with Your Will

Asset Recommended Approach Why
Superannuation Binding nomination to estate (or reversionary) Flows to testamentary trust
Life insurance (outside super) Beneficiary: estate Flows to testamentary trust
Life insurance (inside super) Same as super, nominate to estate Combined with super
Income protection Benefits go to you while alive N/A for estate planning

Sample Super/Insurance Setup for Parents

The Patel Family Setup:

  • Dad's super ($450,000): Binding nomination → Estate → Testamentary Trust
  • Mum's super ($280,000): Binding nomination → Estate → Testamentary Trust
  • Dad's life insurance ($1M): Beneficiary → Estate → Testamentary Trust
  • Mum's life insurance ($500K): Beneficiary → Estate → Testamentary Trust

Total protection for children: $2.23M, all flowing through properly managed trust

Keeping Nominations Current

Task Frequency Consequence of Not Doing
Review binding nominations Every 3 years Nomination lapses, fund decides
Update after life events New child, relationship change Nomination may be outdated
Check for non-lapsing options When reviewing super May need to renew less often
Confirm after changing funds When switching super New fund has no nomination
Review all funds Annually May have multiple funds

Common Super/Insurance Mistakes

Mistake Consequence Solution
No binding nomination Fund decides where super goes Complete nomination immediately
Nomination to children directly Receive at 18, no trust protection Change to estate
Nomination to ex-spouse Ex receives super despite separation Update immediately after separation
Expired binding nomination Reverts to fund's discretion Renew before expiry
Forgot about old super funds May go to wrong person or be unclaimed Consolidate funds
Life insurance to wrong beneficiary Bypasses will/trust Review all policies

If Parents Disagree on Guardian

Married/Together Parents

Both parents should ideally:

  • Discuss and agree on guardian choice
  • Nominate the same person in their wills
  • Include the same alternates in the same order
  • Review together when circumstances change

If parents name different people:

  • The court must decide between competing nominations
  • Creates uncertainty and potential family conflict
  • Children may be traumatised by dispute
  • Legal costs from the children's inheritance

Resolution approaches:

  1. Compromise: Agree on someone you both accept
  2. Prioritise: One parent's choice as primary, other's as alternate
  3. Mediation: Use family counsellor if can't agree
  4. Lawyer advice: Get professional guidance on best approach

Separated/Divorced Parents

Situation Consideration Recommendation
Equal custody Both parents' nominations carry weight Try to agree for children's sake
Primary carer Primary parent's wishes may carry more weight Primary parent should have clear nomination
Estranged parent Their nomination may still be considered Document concerns in will
Court orders Existing parenting orders may be relevant Consider in nomination
New partners May want to exclude ex's new partner Can express this wish

Best approach: Even if separated and in conflict, try to agree on guardian nominations, your children's welfare should transcend personal disputes. Consider family mediation focused specifically on this issue.

Documentation to Support Your Choice

If you anticipate disagreement or have concerns about the other parent's likely nomination, document:

  • Why you chose your nominated guardian
  • Your concerns about alternatives
  • Your children's relationships with potential guardians
  • Your parenting values and approach
  • Any professional advice received
  • Discussions with your nominated guardian

This doesn't guarantee the court will follow your wishes, but it provides important context.

Special Situations

Children with Disability or Special Needs

Consideration Approach
Guardian capability Must understand child's needs, willing to provide lifelong care
Trust structure May need to continue beyond 18 (lifetime trust)
Centrelink impact Trust must be structured to preserve benefits
NDIS considerations Guardian must navigate ongoing support needs
Accommodation Long-term housing needs planning
Professional advice Essential, special needs planning is complex

Special Disability Trust (SDT): Consider whether a Special Disability Trust is appropriate, these have specific Centrelink exemptions but strict rules. Professional advice essential.

Sample lifetime trust clause:

"The trust for [Child's Name] shall continue for [their] lifetime and shall not vest at any particular age. The Trustees shall use the trust fund for [their] maintenance, education, advancement, and welfare, having regard to [their] disability and [their] entitlement to government benefits."

Children Living in Different Locations

Scenario Options
Siblings in different households Can nominate different guardians; strongly consider impact on sibling relationship
Children overseas Complex, may need international planning, different jurisdictions
Shared custody with other parent Consider where children currently live, school, friends
Children with different other parents May need different arrangements for different children

Very Young Children

For infants and toddlers:

  • Ensure guardian can meet needs of very young children
  • Consider that needs will change dramatically over 15+ years
  • Choose someone with parenting experience
  • Plan for childcare arrangements
  • Consider guardian's work flexibility

Teenagers

For children aged 13-17:

  • Consider including older teenagers in discussion
  • Think about someone who can handle adolescence
  • Guardian should be willing to set appropriate boundaries
  • Consider whether teen would actually live with guardian
  • Think about transition to independence

Multiple Children of Different Ages

Approach Considerations
Same guardian for all Keeps siblings together (preferable), guardian must handle multiple ages
Different guardians May be appropriate for very different needs, but separates siblings
Age-based planning Different plans for younger vs older children

Strong recommendation: Keep siblings together unless there's a compelling reason not to. Separation compounds trauma.

Common Mistakes Parents Make

In Guardian Appointments

Mistake Problem Solution
No guardian nominated Court decides, may not be your choice Nominate in your will
Only one guardian, no alternates If primary can't serve, back to court Always include 1-2 alternates
Didn't ask the guardian They may decline when the time comes Have a proper conversation
Chose based on obligation Family pressure, not best choice Choose who's genuinely best
Didn't consider children's view Older children may have preferences Include children appropriately
Outdated nomination Guardian may have moved, divorced, or become unsuitable Review every 2-3 years
Parents nominate different people Creates conflict and uncertainty Agree on same nominations

In Financial Arrangements

Mistake Problem Solution
No trust, children inherit at 18 18-year-old receives large sum Create testamentary trust
Same person as guardian and trustee No financial oversight Consider separating roles
No guardian support provisions Guardian financially burdened Include support clauses
Super nominations don't align Super bypasses will/trust Update super nominations
Trust terms too restrictive Trustee can't meet genuine needs Include broad discretionary powers
Trust terms too loose No guidance for trustee Include directions and wishes

Sample opening:
