Naming Guardians for Minor Children in a Florida Estate Plan

Naming a guardian for minor children in a Florida estate plan means using your will to nominate the adult you want a court to appoint to raise your children if both parents die or become incapacitated. In Florida, that nomination is made under Chapter 744 of the Florida Statutes and is honored by the court unless the chosen person is unfit or unavailable. The nomination is a request to the court, not an automatic transfer of custody, which is exactly why getting the details right matters so much for South Florida families.

I have sat across the table from a lot of parents in Key West and throughout the Keys who assumed this was a box to check. It isn’t. The guardian decision is the single most personal choice in a young family’s estate plan, and in blended families and second marriages it is often the most complicated one too. Below is how it actually works in Florida, where people go wrong, and how to draft a nomination that holds up.

Two kinds of guardianship: the person and the property

Florida law splits guardianship of a minor into two distinct roles, and a clean estate plan addresses both.

• Guardian of the person. This is who raises the child day to day: where the child lives, goes to school, sees the doctor, and grows up. This is the role most parents picture when they think about “naming a guardian.”
• Guardian of the property. This is who manages money and assets that come directly to the child until they reach the age of majority. Florida requires a property guardianship whenever a minor receives assets exceeding the statutory threshold, currently $15,000, under section 744.387 and related provisions.

Here is the trap. The person who is wonderful at bedtime stories and homework is not always the person you want signing off on an inheritance. You can name the same individual for both roles, or you can split them deliberately. Splitting is common, and it is smart when your most trusted caregiver is not your most disciplined money manager.

Why a trust usually beats a property guardianship

A court-supervised property guardianship under Florida law is rigid and expensive. The property guardian posts a bond, files annual accountings, and must get court approval for many expenditures. Worse, whatever is left transfers outright to the child at age 18, which is rarely what any parent intends.

Most of the families I work with avoid all of that by funding a trust instead. A revocable living trust, or a testamentary trust written into the will, lets you name a trustee, set the ages at which money is distributed, and skip the annual court reporting that a property guardianship requires. The guardian of the person raises your child. The trustee holds and releases the money on your timetable. That separation is the workhorse of a well-built young-family plan, and the same trust structure that protects a typical child is the foundation of a when a child has a disability and you need to preserve eligibility for public benefits.

How you actually nominate a guardian in Florida

You name a guardian in your last will and testament. Under section 744.3046 of the Florida Statutes, a parent may nominate a guardian for a minor child, and the court gives that nomination substantial weight. A few practical points that surprise people:

1. It must be in a valid Florida will. A note in a drawer, a text to your sister, or a slot in a phone app does not nominate a guardian. The will has to meet Florida’s execution requirements under section 732.502: signed by you and two witnesses who sign in each other’s presence and yours.
2. Both parents should nominate. If you are married, each spouse names the guardian in their own will. The surviving parent keeps custody automatically; the nomination only takes effect when no parent is able to serve.
3. Name backups. Life changes. Your first choice may move out of state, get sick, or simply decline when the moment comes. Name a first, second, and ideally a third choice so a judge is never guessing.
4. The court still decides. A Florida judge applies a best-interests standard and can decline your nominee if that person is unfit, but absent a real problem, your written choice almost always controls.

Pre-need guardian designation: the often-missed step

Florida offers a second tool that many wills skip. Under section 744.3046, a parent can file a separate written declaration of a pre-need guardian. This document can name a guardian to serve if the parent becomes incapacitated, not just deceased. It is filed with the court and produced if and when it is needed. For a single parent, or for a parent with a serious health condition, this covers the gap that a will alone leaves open. A will speaks at death; a pre-need designation speaks during a living incapacity.

Guardianship in blended families and second marriages

This is where Key West families most often need careful drafting, and it is the heart of how we approach these plans. Second marriages reshuffle the usual assumptions, and a generic will tends to create more conflict than it resolves.

Consider the common scenario: each spouse brings children from a prior relationship. If you die, your children’s surviving legal parent is typically your ex-spouse, not your current husband or wife. Your new spouse does not automatically get custody of your children no matter how close they are, unless they have legally adopted. A stepparent who has not adopted has no inherent custody right under Florida law. So the questions get pointed fast.

• Whose children are we talking about? Address each child individually. A blended household may need different guardians for different kids if the legal parents differ.
• Is the other biological parent in the picture? If yes, your nomination of a third party may be challenged by that parent, who has constitutional standing. Be realistic about what your will can and cannot override.
• Do you want your new spouse to raise your kids? If so, and the other biological parent is absent or deceased, say so explicitly and explain why in a letter of intent. Courts pay attention to a parent’s stated reasoning.
• How do you keep money fair? Separate the caregiving decision from the inheritance decision. Use trusts so a stepparent guardian is not also controlling your children’s money, which is a frequent source of resentment and litigation in blended families.

I always tell second-marriage clients to write a short, private letter of intent that lives alongside the will. It is not legally binding, but it tells a judge and your family why you chose who you chose, how you want the children’s relationship with both sides maintained, and what values matter to you. In a contested case, that letter can be the difference-maker.

Choosing the right person: a practical checklist

Strip away the legal mechanics and you still have to pick a human being. Run candidates through a few honest questions:

• Does this person genuinely want the role, and have you asked them out loud?
• Are they at a life stage that matches your children’s needs for the next decade or more?
• Do their values, religion, and parenting style line up with yours?
• Where do they live? A guardian in another state means uprooting your children from school, friends, and the Keys.
• Can they handle the financial responsibility, or should someone else manage the money through a trust?
• Will naming this person create a rift with another relative who expected the role? Plan how you will communicate the decision.

Do not name co-guardians who do not get along, and think hard before naming a married couple jointly, because divorce or a death between them can scramble your plan. If you do name a couple, address what happens if they separate.

What happens if you never name anyone

If you die without nominating a guardian, your children are not left in limbo, but the decision moves entirely into a courtroom. Relatives may petition, sometimes more than one at a time, and a judge who never met your family decides who raises your children. That process is slower, more expensive, and far more likely to splinter a family than a clear nomination would have been. In a blended family, where two sets of relatives may each step forward, the absence of a written choice is an invitation to a fight. The whole point of the estate planning and probate process is to keep your wishes, not a stranger’s guess, in control.

Keep the nomination current

A guardian nomination is not a one-time event. Review it after a birth, a death, a divorce, a remarriage, a move, or a falling-out with your named guardian. The person who was perfect when your child was a toddler may be wrong by the time that child is a teenager. A plan that sits untouched for fifteen years often names people who have moved, aged, or drifted away. We build periodic reviews into every young-family plan for exactly this reason. If you would rather start with a foundational document, a properly drafted will and trust package, the same building blocks Morgan Legal uses in its work, is where the guardian nomination lives.

Frequently Asked Questions

Can I name a guardian for my children without a will in Florida?

Not effectively. Florida law requires the nomination to appear in a validly executed will under section 732.502, or in a separate pre-need guardian designation under section 744.3046. A note, text, or app entry does not legally nominate a guardian, and without a valid document the court decides on its own.

Does naming a guardian mean my new spouse cannot raise my kids?

It depends on the legal parentage. If your child’s other biological parent is alive and has rights, that parent usually keeps custody regardless of your nomination. If the other parent is absent or deceased, you can nominate your spouse, but a stepparent who has not adopted has no automatic custody right, so you should name them explicitly and explain your reasoning.

What is the difference between a guardian of the person and a guardian of the property in Florida?

The guardian of the person raises the child day to day. The guardian of the property manages money and assets the child inherits, which Florida requires when a minor receives more than $15,000. You can name the same person for both or split the roles, and most families use a trust to avoid a court-supervised property guardianship entirely.

What happens to my children if I die without naming a guardian?

A Florida court decides. Relatives may petition for guardianship, sometimes competing with one another, and a judge applies a best-interests standard. The process is slower, costlier, and more likely to divide a family than a clear written nomination, which is especially risky in blended families with two sets of relatives.

How often should I update my guardian nomination?

Review it after any major life change: a birth, death, divorce, remarriage, move, or a change in your relationship with the named guardian. At a minimum, revisit it every few years so your nomination still names people who are willing, able, and appropriate for your child’s current age and needs.
