Not the minor, and usually not the surviving parent automatically. Who controls the money depends entirely on how it was left, and the four common structures produce very different answers about when an eighteen-year-old can walk in and take it.
Can a minor inherit directly in California?
A minor can own property but cannot manage it, and financial institutions will not deal with them. So something has to sit in between, and if the estate plan didn’t supply that something, the court will.
That gap is the problem. A beneficiary designation naming a seven-year-old on a life insurance policy is a guardianship proceeding waiting to happen.
What are the four ways money reaches a minor?
Each has a different controller and a different end date.
- A trust. The trustee controls it, on the terms the settlor wrote, and distribution can be staged to any age. This is the flexible option and the one worth having.
- A custodial account under the California UTMA. A custodian controls it and it ends at a fixed statutory age, which is where families get caught out.
- A guardianship of the estate. A court-appointed guardian controls it under court supervision, with bond, accountings, and hearings. Expensive and slow.
- A blocked account. Funds are frozen at a bank until the minor turns 18, then released in full.
When does a UTMA account actually end?
Sooner than most parents assume. California’s default termination age is 18, and it only runs to 21 or 25 where the transfer was set up that way at the time it was made.
The consequence is blunt: on that birthday the young adult can demand the entire balance and spend it on anything. The custodian has no discretion to refuse. Our page on what happens to a UTMA account when a child turns 18 covers the mechanics and the fix.
If a substantial sum is sitting in a custodial account for a fifteen-year-old, that is a problem with a three-year fuse.
Does the surviving parent control the money?
Only if the document says so, and being the parent is not enough. A parent is the child’s natural guardian for personal decisions, and that does not carry authority over the child’s property.
Where money was left to a minor with no trust and no custodian, the surviving parent typically has to petition for guardianship of the estate. That’s a court case, with a bond, annual accountings, and court approval for expenditures.
It’s also the moment blended-family problems surface. If your ex-spouse becomes guardian of the estate of the money you left your child, they are the one filing the accountings. See blended family estate planning.
What does a trustee for a minor actually do?
Holds, invests, and distributes on the trust’s terms, and stands in a fiduciary relationship to the child. Duties don’t soften because the beneficiary is young.
They still owe prudence, impartiality among beneficiaries, and accountings. Under Prob. Code § 16460(b)(3), a minor is deemed to have received an account if it goes to their guardian, or to a parent where there’s no guardian and the parent has no conflict of interest.
That last clause matters. A parent who is also the trustee has a conflict, and delivering the accounting to themselves does not start the limitation clock against the child.
What should I do if I’m planning for young children?
Use a trust and stage the distributions on purpose. Handing a lump sum to an eighteen-year-old is a decision, and most parents making it don’t realise they’re making it.
Common staging is a third at 25, a third at 30, a third at 35, with the trustee able to distribute earlier for health, education, maintenance and support. See what HEMS means in a trust.
Then check the beneficiary designations. Retirement accounts and life insurance pass by contract, not by your will, and a policy naming a minor directly bypasses the trust you just built. Our beneficiary designation audit exists for exactly this.
