Choosing a Guardian for Your Minor Children

Family · 6 min read · Updated September 16, 2026

A guardian is the person a court appoints to raise a minor child if both parents die or become unable to care for the child. Parents nominate a guardian in their will, and courts give that nomination strong weight, though the judge makes the final decision based on the child’s best interests. Naming a guardian and an alternate is the main reason many parents of young children make a will at all.

What a guardian does

A guardian of the person has custody of the child: where the child lives, goes to school, receives medical care, and practices religion. The guardian makes day-to-day and major decisions until the child turns 18.

Separately, a guardian of the estate (called a conservator or custodian in some states) manages money and property belonging to the child. The same person can hold both roles, or they can be split. A will can nominate someone for each and can also set up a trust to hold the child’s inheritance under a trustee, which avoids court supervision of the money.

How the nomination works

Only a will can formally nominate a guardian in most states. A letter or a conversation is not enough, though some states allow a separate written nomination. The nomination becomes relevant only if no parent is living and able to serve. A surviving parent generally keeps custody regardless of what the deceased parent’s will says, with narrow exceptions where the surviving parent’s rights have been terminated.

When both parents are gone, the court reviews the nomination and appoints the named person unless there is a serious reason not to. Reasons might include the nominee’s declining the role, the nominee’s inability to care for the child, or evidence that the nomination is contrary to the child’s welfare. Relatives can object, and the court will hear them, but a clear nomination in a will is the strongest evidence of the parents’ wishes and usually prevails.

If there is no nomination, the court chooses among family members who come forward, without guidance from the parents. See What Happens If You Die Without a Will?.

Questions to consider

There is no perfect guardian. Most parents are choosing among imperfect options and trading off different priorities. Useful questions include:

Values and parenting style. Would this person raise the child roughly as the parents would? Perfect alignment is impossible; broad compatibility on discipline, education, and religion matters more.

Relationship with the child. Does the child already know and trust this person? Moving in with a beloved aunt is easier than moving in with a relative the child has met twice.

Age and health. Grandparents are often the emotional first choice, and for a young child they may not be able to see the job through to age 18. Some parents name grandparents with a younger alternate; others name a sibling with grandparents as a supporting presence.

Location. Would the child have to change schools, leave friends, and move far from other family? Sometimes that is unavoidable; it is worth weighing.

Family situation. Does the nominee have children of their own? Would adding one or more children strain the household? Is the nominee’s marriage stable? If the nominee is married, is the nomination to one spouse or both?

Finances. Raising a child is expensive. The guardian is not expected to pay for it personally, which is why life insurance and the child’s inheritance matter, but a guardian in precarious financial circumstances may struggle with the added demands.

Willingness. Has the person been asked? Some people would say yes without hesitation; others would find the responsibility overwhelming. The conversation is essential.

Naming a couple

Parents often want to name a married sibling and their spouse together. This works, but it raises a question: if the couple divorces, or one of them dies, who serves? Some parents name only the blood relative. Others name both and add language about what happens if they separate. The questionnaire on this site asks for a single guardian and an alternate, which keeps the nomination unambiguous; parents who want to name a couple can discuss the wording with an attorney.

The alternate

The alternate guardian serves if the first choice cannot or will not. Circumstances change: the first choice may move abroad, develop health problems, or simply feel differently ten years later. Without an alternate, the court is back to choosing without guidance. The alternate deserves the same thought as the primary, and the same conversation.

Separating the money from the child

Some parents trust a sibling to raise their children but not to manage a large sum. Others trust a financially savvy friend with money but would not want them raising a child. Naming a different guardian of the person and trustee of the child’s funds addresses this, and the trustee can be required to pay the guardian for the child’s expenses. This split is common and not an insult to either person.

Without a trust, a minor’s inheritance is typically held by a court-supervised guardian of the estate or a custodian under the state’s Uniform Transfers to Minors Act, and the child receives it outright at 18 or 21. Many parents prefer a trust that distributes at a later age or in stages. A trust for minors can be created inside the will; parents who want one are encouraged to have an attorney review the terms.

Writing a letter

The will nominates the guardian; it does not explain the parents’ hopes. Many parents write a separate, non-binding letter to the guardian covering things like the child’s routines, medical history, religious upbringing, relationships the parents want maintained, and what the parents would want the child to know about them. The letter has no legal force but can be a great gift to both the guardian and the child. It is kept with the will, not in it.

Revisiting the choice

A guardian nominated when a child is two may not be the right choice when the child is fourteen. The nominee’s life changes; the child’s needs change; the child may have opinions. Parents who reread their will every few years, and after events like a nominee’s divorce or move, keep the nomination current. See When to Update Your Will.

Frequently asked questions

Is the guardian named in a will legally binding?

The nomination is not automatically binding, but courts give it strong weight and appoint the nominee unless there is a serious reason not to. A surviving parent generally keeps custody regardless of the nomination.

Can a guardian be someone who lives in another state or country?

Yes. The court may consider the disruption to the child of relocating, but distance alone does not disqualify a nominee. International guardianship involves additional legal steps and is worth discussing with an attorney.

Does the guardian control the child’s inheritance?

Not necessarily. A will can name a separate trustee or guardian of the estate to manage the money, and many parents do this. If no one is named, the court appoints someone to hold the funds until the child reaches the age of majority.

What if the parents disagree about the guardian?

Each parent’s will nominates a guardian. If both parents die and the wills name different people, the court decides, weighing both nominations. Parents who can agree on one nominee, and name the same person in both wills, give the court the clearest guidance.

Ready to make your will?

The questionnaire at /start asks for a guardian and an alternate whenever minor children are listed and produces a will that includes the nomination. Guardianship procedures and signing requirements differ from state to state; see the guide for a specific state at /wills/, and have the finished will reviewed by a licensed attorney before signing.
