Can you leave a child out of your will?
I’m sure we’ve all been tempted when they were giving us attitude! But in all seriousness, estate planning involves thoughtful decisions shaped by the reality of your family situation. So can you actually leave an adult child out of your will? In California, yes, you can. There is no law that says a parent has to leave anything to a grown child. Whether you're estranged, or your child is doing well on their own, or you've simply decided the money should go somewhere else, the decision belongs to you. Your estate is yours to divide however you want, and that can include leaving someone out.

The thing people really want to know is whether that choice will hold up. And that depends a lot on how it's done. The most common mistake people make is saying nothing at all and letting them find out when the will is read. That can feel like the kinder choice, or at least the way that avoids a direct confrontation, but it leaves the door open in a few ways.
A child born or adopted after you sign your will can usually claim the share they'd get if you had no will, unless your documents show you left them out on purpose.
Silence can backfire
California has a set of rules for omitted children in Probate Code sections 21620 through 21622. The first covers a child who is born or adopted after you've signed all of your estate planning documents. If you didn't provide for that child, the law treats it as an oversight and gives the child the share they'd have received if you had died with no will or trust at all. A common version is a couple who sign their documents with two kids, adopt or have a third years later, and never go back to update their paperwork. Unless an exception applies (or this possibility was explicitly accounted for in the trust), that third child can ask the court for a share on the assumption that nobody meant to cut them out.
There are three exceptions to this rule, and the first is most important. A child doesn't get a share if you left them out on purpose and that intent appears in the will or trust itself. A note in a drawer or a talk at Thanksgiving doesn't count, because the law looks at the documents. The other two cover a parent who left nearly all of the estate to the child's other parent and a parent who gave the child something outside the estate, like a life insurance policy, and meant it to take the place of an inheritance. For that second one, your own words, the size of the gift, or other evidence can show what you meant.
As an aside, one of these rules covers a child who was already alive when you signed, but whom you didn't know about or believed had died. That child can claim a share only if that was the sole reason you left them out, and the child has to prove it. It's a narrow rule, but it does come up.
If you knew about your child when you signed, the omitted-child rules generally don't give that child a share, which is why you'll hear people say that silence works fine. It might. It also leaves your intent open to question, and a child who feels overlooked may try other routes, like claiming you lacked capacity or were pressured by someone. A plain statement that you chose not to provide for a child makes it much harder to argue that you simply forgot. Many people also add a short line saying they've left out anyone not named, including children born or adopted later. At least one California appeals court has held that a general clause like that can defeat omitted-child claims.
What a no-contest clause can and can't do
A lot of people hear "no-contest clause" and assume it settles everything. It's a provision saying that anyone who challenges the will or trust (and loses that challenge) loses whatever they were given. California has narrowed how far it reaches. Since 2010, a clause can mostly be enforced only against a direct contest, meaning a challenge to whether the document is valid because of things like forgery, fraud, or undue influence, and only if the challenge was filed without probable cause. Probable cause means the facts known at filing would lead a reasonable person to believe there's a solid chance of winning once there's been more investigation. The challenger doesn't have to win to be safe. A clause can also reach a fight over who owned a piece of property, or a creditor's claim, but only if the clause says so outright, and courts read these clauses narrowly.
A clause only works on someone who has something to lose, and a child who was set to get nothing anyway has nothing to forfeit by challenging the will. Some people leave a modest gift so the clause has something to take away, though that is not our preferred method for various reasons discussed in other posts. A no-contest clause can, however, still keep other beneficiaries in line, like a sibling who's thinking about joining a challenge, because they have a share at stake.
A child who receives nothing has nothing to lose, so a no-contest clause gives that child no reason to hold back from a full legal challenge.
Making the decision hold up
If you've decided to leave a child out, your documents should name every one of your children and say plainly which one you've chosen not to provide for. If you want that to cover children born or adopted later, include that as well. You don't have to give reasons, and it's often better not to, since a stated reason can become something to argue about.
Then there's everything your will or trust doesn't control. Retirement accounts and life insurance go to whoever is on the beneficiary form, and joint accounts go to the surviving owner, so a child you left out of your will but left on a form will still collect. It's worth checking those forms when you sign your documents. And if you're married, your spouse already owns half of your community property, so what you direct is mostly your half and your separate property.
Retirement accounts and life insurance go to the person named on the beneficiary form, no matter what the will says.
Births, adoptions, marriages, and divorces are the moments when plans like this tend to go out of date, so those are good times to look again. Leaving a child out is a personal choice, and the wording of it is important, so talk it through with an attorney before you sign anything.
