Short answer: For a California single parent, the document that matters most is a will that nominates a guardian for your children, because that is not something a trust, life insurance policy, or beneficiary designation can do for you. If you die without a will, California’s intestate succession statutes (Probate Code § 6400) decide who inherits your property, and a judge decides who raises your children with no written guidance from you at all. A trust can add control over how and when your children actually receive money. It does not replace the guardian nomination in a will.
What happens to my children if I die without a will?
Two separate questions come up when a single parent dies without a will: who raises the children, and who gets the property. California’s intestate succession statutes answer only the second question. Under Probate Code § 6402, if there is no surviving spouse, the estate passes first to the decedent’s children. That statute has nothing to say about who takes physical custody of a minor child or manages that child’s inheritance day to day.
Dying without a will also does not avoid probate. An intestate estate above the small estate threshold still goes through the same court-supervised probate process, under the same statutory fee schedule, as an estate with a will (Probate Code §§ 10800 and 10810). For a single parent, that means court costs and statutory fees come out of the estate before your children see a dollar of it.
How do I name a guardian for my children in California?
A parent can nominate a guardian for a minor child in a written document, most commonly a will. Courts give real weight to a parent’s written nomination and, absent a good reason not to, will typically appoint the person the parent named. Without a nomination, the court decides based on the child’s best interest, using whatever family members or petitioners come forward, which can mean a relative you would not have chosen, or a contested proceeding between relatives who disagree.
Naming a guardian is a decision, not paperwork you can skip and fix later. Pick someone whose parenting values and daily stability you trust, talk to that person before you name them, and name at least one backup in case your first choice cannot serve when the time comes.
Does a will alone protect my children’s inheritance?
A will lets you nominate a guardian and direct who inherits your property, but a will by itself does not avoid probate. It only takes effect once a court validates it through the probate process. For a single parent with a modest estate, that process has a real cost: the statutory fee for a probate executor runs 4 percent of the first $100,000, 3 percent of the next $100,000, 2 percent of the next $800,000, and smaller percentages above that, and the estate’s attorney is entitled to an identical fee calculated the same way (Probate Code §§ 10800 and 10810). On a $1,000,000 estate, that schedule produces $23,000 for the executor and another $23,000 for the attorney, or $46,000 in ordinary statutory fees alone, before court costs or bond. That is money that would otherwise go to your children.
A will is still necessary even if you also use a trust, because it nominates the guardian and catches anything you never got around to retitling. But if avoiding probate cost and delay matters to you, a will alone will not do it. See wills for how a will fits into a broader plan.
Should a trust hold my children’s inheritance instead of a will?
Only a funded revocable living trust, meaning one where your assets are actually retitled into the trust’s name, passes property to your children outside of probate. A trust you sign but never fund does nothing for the assets you never transferred into it. A trust also lets you control the terms of inheritance directly: instead of your child receiving a lump sum outright at 18, you can specify a trustee who manages and distributes the money over time, for education, housing, or whatever needs you define.
One common misconception is worth correcting directly: a revocable living trust does not reduce income tax, property tax, or estate tax (Revenue and Taxation Code § 13301). California has no state estate tax or inheritance tax at all. On the federal side, the 2026 estate and gift tax exemption is $15,000,000 per person under IRC § 2010(c), so most single parents will never owe federal estate tax regardless of whether they use a trust. The reason to use a trust is control and probate avoidance, not tax savings. Learn more about living trusts.
What about life insurance, and what if I become incapacitated rather than deceased?
Life insurance with a named beneficiary passes outside of probate directly to whoever you name, which makes it one of the fastest ways to get money to your children. The complication is that a minor cannot directly receive or manage a large payout. Naming a young child outright as a life insurance beneficiary, without more, generally means a court-appointed guardian of the estate has to be involved to manage the funds until the child turns 18, which adds cost and court oversight you could have avoided by naming a trust as the beneficiary instead.
Death is not the only risk a single parent plans for. If you become incapacitated rather than deceased, someone still needs authority to make medical decisions and manage finances for you, and to step in for your children in the meantime. A power of attorney and an advance health care directive let you designate, in advance, who has that authority, so a court does not have to appoint someone through a conservatorship proceeding. A guardian nomination can also address who cares for your children on a temporary basis if you become incapacitated, not just if you die. See powers of attorney for how these documents work.

What to do next
If you are a single parent without a will, the guardian nomination is the piece you cannot get anywhere else, so start there. From there, decide whether a trust makes sense for controlling how and when your children actually receive what you leave them. An estate planning attorney can put a will, guardian nomination, trust, and incapacity documents together as one coordinated plan rather than separate pieces that do not talk to each other.
