Most parents think of estate planning as a money question. For anyone with children under eighteen, it is not. The largest decision in the document has nothing to do with assets: it is who raises your children if you are not there to do it.

Quick Answer: California Probate Code section 1500 lets a parent nominate a guardian for a minor child in a will or another signed writing. A nomination is not an appointment — a judge still makes the final call under the child’s best-interest standard. But a clear, current nomination is the strongest signal the court has, and without one the court chooses with no guidance from you at all.

What a Guardian Nomination Actually Does
Under California Probate Code section 1500, a parent can nominate a guardian for a minor child. That nomination usually lives in a will, though it can be made in a separate signed writing.
What it does not do is appoint anyone. Guardianship of a minor in California is a court proceeding. Someone — usually the person you named — has to petition the Superior Court, the court investigates, and a judge decides under Probate Code section 1514, applying the child’s best interest.
In practice the nomination carries real weight. Judges are being asked to make an intimate decision about a family they have never met, and a parent’s written choice is the closest thing to direct evidence of what the family would have wanted. A nomination that is clear, recent, and accompanied by a short explanation of why is far more useful to a court than a name on a line.
What Happens When No Guardian Is Named
If nobody is nominated, the court still has to appoint someone. It just does so without your input.
The immediate problem is not usually who wins — it is the gap. Between the day a parent dies and the day a court appoints a guardian, the adults caring for your children have no legal authority. Grandparents and family friends who step in cannot, on their own:
- Consent to medical treatment beyond an emergency
- Enroll a child in a new school or authorize special education services
- Access the child’s accounts, benefits, or insurance
- Make decisions about travel, counseling, or religious upbringing
That gap is also where family disagreement does the most damage. When two relatives each believe they are the right choice and there is nothing in writing, the disagreement goes to a judge — and the children live inside that uncertainty while it is resolved.
Your children’s future shouldn’t depend on a judge’s best guess.
Guardian of the Person Is Not Guardian of the Estate
California treats these as two separate jobs, and they do not have to go to the same person.
- Guardian of the person raises the child — home, school, medical care, day-to-day life.
- Guardian of the estate manages money and property that belongs to the child.
Splitting them is common and often wise. The sibling who would give your children the most stable home is not automatically the person you want managing an inheritance and filing accountings with the court for the next fifteen years.
It is worth saying the quiet part out loud: naming the same person for both, purely to avoid an awkward conversation, is one of the most common planning mistakes we see.
Naming a Guardian Is Only Half the Job
A minor cannot simply receive an inheritance. If money lands in a child’s name with no structure around it, California’s default answer is a guardianship of the estate: court supervision, periodic accountings, and a hard stop at eighteen, when whatever is left is handed over outright.
Very few parents actually want that. An eighteen-year-old receiving a lump sum with no guidance is not the plan anyone describes when you ask them what they want for their children.
The alternative is a trust. Rather than money passing to the child, it passes to a trustee you chose, to be used for the purposes you described, released on a schedule you set. That is why the guardian nomination and the trust are two halves of the same decision — see how a will and a living trust divide this work for how the pieces fit together.
Name the guardian. Then make sure the money has a plan too.
The Mistakes We See Most
- Naming a couple, not a person. “My sister and her husband” becomes a live question if that marriage ends.
- No alternate. Your first choice may be unavailable, unwilling, or gone. Name at least one backup, ideally two.
- Never telling the person. A nomination is not a binding obligation; anyone named can decline. Finding out at the worst possible moment that they will decline is avoidable.
- Choosing on affection alone. Location, age, health, existing children, and financial stability all shape whether an arrangement actually holds.
- Leaving it stale. A nomination naming a guardian who has since moved across the country, remarried, or fallen out of contact tells the court less than you think.
Keeping the Nomination Current
Guardian nominations age faster than the rest of an estate plan, because they depend on other people’s lives, not just yours. Revisit yours when your children reach school age, when a named guardian moves or has a major life change, and any time your own family structure changes.

Frequently Asked Questions
Does naming a guardian in my will guarantee that person gets my children?
No. A nomination under California Probate Code section 1500 is a strong recommendation, not an appointment. The court still appoints a guardian under Probate Code section 1514, applying the child’s best interest. In practice courts give a parent’s written nomination significant weight, especially when it is recent, unambiguous, and unopposed.
Can I name one person to raise my children and someone else to manage their money?
Yes, and it is often the better structure. California separates guardian of the person from guardian of the estate, and most families handle the money side through a trust with a named trustee rather than a court-supervised guardianship of the estate.
What happens between my death and the court appointing a guardian?
There is a gap, and during it the adults caring for your children have no legal authority to consent to medical care, enroll them in school, or access their accounts. A clear nomination shortens that gap because it tells everyone who should be petitioning. Some families also put a short-term arrangement in place for the first days.
I’m divorced and my children’s other parent is living. Does my nomination control?
Generally no. A surviving legal parent who is fit ordinarily has priority over a guardian nominated by the other parent. A nomination still matters, because it governs if the other parent is unavailable, unwilling, or found unfit, and because circumstances change.
How often should I revisit my guardian nomination?
Every three to five years, and immediately if a named guardian moves, has a significant life change, or you have another child. Guardian nominations depend on other people’s circumstances, so they go out of date faster than the rest of an estate plan.
Key Takeaways
- California Probate Code section 1500 lets you nominate a guardian; the court still appoints under the best-interest standard.
- With no nomination, a judge chooses with no guidance from you, and caregivers have no legal authority until a court acts.
- Guardian of the person and guardian of the estate are separate roles and can go to different people.
- A trust is what keeps an inheritance from being handed over outright at eighteen.
- Name alternates, tell the people you named, and revisit the nomination every few years.
