Short answer: In California, you decide who raises your minor children by nominating a guardian in your estate plan, not by hoping a judge lands on someone you would have chosen. A will still has to go through probate before that nomination takes legal effect, and money or property left directly to a minor, without a trust in place, can trigger a court-supervised guardianship of the estate that controls those assets until the child reaches adulthood. A funded trust, paired with a guardian nomination, keeps both decisions with you instead of with the court.
Who decides who raises my children if I can’t?
If you nominate a guardian for your minor children in your will, the court gives that nomination substantial weight when both parents have died or become unable to care for the children. If you die without naming anyone, a judge decides based on the child’s best interest, without ever knowing who you would have trusted. Whoever petitions the court first, a relative, a family friend, or someone the rest of the family never expected, can end up in that role.
Naming a guardian costs you nothing beyond including it in your estate plan. Not naming one leaves a gap that a judge fills after the fact, on a timeline and with information you had no part in shaping.
What is the difference between guardianship of the person and guardianship of the estate?
California recognizes two separate roles. Guardianship of the person covers day-to-day care: where the child lives, goes to school, and receives medical treatment. Guardianship of the estate covers the child’s money and property, and it comes with ongoing court supervision, required accountings, and restrictions on how funds can be spent, all of which continue until the child reaches adulthood.
You can nominate the same person for both roles or split them, naming one relative to raise the children and a different person or institution to manage the money. Many parents split the roles on purpose, because raising children well and managing money well are different skills.
How does a trust change this for my children’s inheritance?
Accounts held in joint tenancy, or with a payable-on-death, transfer-on-death, or named beneficiary designation, generally pass outside of probate directly to whoever is named. That sounds simple until the person named is a minor. A bank, brokerage, or insurance company still cannot hand money straight to a child. Someone has to petition to become guardian of the estate, and that guardianship stays open under court supervision until the child reaches adulthood and receives the full balance at once, whether or not they are ready for it.
A trust avoids that outcome. Once you fund a trust, meaning you actually retitle accounts and property into it and name it as beneficiary where appropriate, the trustee you chose steps in and manages the assets for your children according to the terms you wrote, not a court’s default rules. A trustee must administer the trust according to its terms and California law, with a duty to act within a reasonable time, under Probate Code § 16000, and may never use trust property for personal benefit, under Probate Code § 16004. Beneficiaries, or the adults acting for a minor beneficiary, are entitled to accountings from the trustee under Probate Code §§ 16060 through 16063, and can petition the court to compel one, or to remove a trustee who falls short, under Probate Code § 17200.
You also decide the distribution structure instead of a single fixed cutoff. A trust can pay for a child’s education and living expenses as needs come up, then release the remaining principal in stages you set, rather than handing over everything the moment the child is legally an adult.
What about a child or dependent with special needs?
If a dependent receives means-tested government benefits, an inheritance paid directly to them can disqualify them from those benefits. A special needs trust is built to hold and manage assets for that dependent’s supplemental care without counting against benefit eligibility. That only works if it is drafted and funded before the dependent inherits anything outright, not scrambled together afterward.
Do I need significant assets before this matters?
No. The guardian nomination decides who raises your children, not how much money is involved, and it matters at any net worth. Even a modest life insurance payout or a small savings account left to a minor without a trust in place can trigger the same court-supervised guardianship of the estate that a much larger inheritance would.

What to do next
Check whether your will actually nominates a guardian for each minor child, and whether that document still reflects your current wishes. If any account, policy, or piece of property names a minor as a direct beneficiary, talk with an estate planning attorney about whether a living trust should sit between that asset and the child, so a court, not you, isn’t the one making the call.
