You are sitting at the kitchen table and finally say it out loud. “I don’t want my spouse to get anything.” Maybe the marriage has been over for years. Maybe there are kids from a first marriage to protect. Maybe the money was yours long before you walked down the aisle.
In California, the short answer is: not completely. You can shape what your spouse inherits, but you cannot write them out entirely with a single line in your will. Community property law gets in the way — and it is much stronger than most people realize. Here is what you actually can and cannot do, in plain English.
So What Does California Actually Say?
California is one of nine community property states. That means almost everything you and your spouse earned or bought during the marriage belongs to both of you equally — 50/50, no matter whose name is on the paycheck or the title. This rule comes from California Family Code section 760.
Here is what that means on the day someone dies. Your spouse already owns half of the house, half of the savings, half of the retirement earned during the marriage. That half is theirs. You cannot give it away in your will because it was never yours to give.
What you can control is your own half. You can leave your share of community property to your kids, to a charity, to a friend, or to no one at all. You can also decide what happens to your separate property — anything you owned before the marriage, or anything you received as a gift or inheritance during the marriage.
So “disinherit a spouse in California” really means this: limit them to their own half of community property, and cut them out of yours.
The First Step Most People Get Wrong

Before you can disinherit anyone, you have to know what you actually own. This is the step most people skip, and it wrecks plans every year in California.
Community property is what you and your spouse built together during the marriage. Paychecks earned after the wedding. The house you bought once you moved in together. The 401(k) contributions made while you were married. All of it is 50/50.
Separate property is yours alone. Assets you owned before the wedding. Gifts made directly to you. Money you inherited from a parent. These stay yours unless you mix them with community funds.
Here is the trap. If you take your inheritance and deposit it into a joint checking account, it can lose its separate status. If you use separate money to renovate a jointly owned house, parts of that value can become community property. Once the line blurs, unraveling it in court is expensive and slow.
So step one is simple in theory and hard in practice: keep separate money separate if you ever want to leave it to someone other than your spouse.
The One Wall You Can’t Knock Down: Community Property
Most people hear “disinherit” and think it’s all or nothing. In California, it’s not.
Here’s the split. Community property is yours and your spouse’s together, 50/50. You control your half. Your spouse controls theirs. No will or trust can override this. That is the wall.
Now here is what you can do.
- Leave your half of community property to someone else. Your kids, a charity, a sibling. This is legal.
- Leave your separate property to anyone you choose. This is where most “disinheriting” actually happens.
- Gift assets during your lifetime. This shrinks the estate you leave behind. California does watch for transfers made to cheat a spouse, so this has limits, but it’s a real option.
- Use beneficiary designations smartly. Life insurance, retirement accounts, and payable-on-death accounts pass outside the will. Retirement accounts usually require spousal consent to name someone else, so this step is not automatic.
The tool most people miss is the prenup — or a postnup if you are already married. A properly signed prenuptial agreement can waive a spouse’s right to inherit. California Family Code section 1615 sets the rules: both people must sign voluntarily, both must see each other’s finances, and both should have the chance to talk to their own attorney. Get these steps wrong and the prenup can be thrown out later.
The Omitted Spouse Trap

Here is where a lot of Californians accidentally give away the farm.
Imagine you wrote your will ten years ago, before you met your current husband. You never updated it. The will leaves everything to your kids. Then you die. Your husband is not named anywhere. Is he out of luck?
No. Under California Probate Code section 21610, he is an “omitted spouse.” California law assumes you just forgot to update your will after the wedding. So he gets half the community property, half the quasi-community property, and a share of the separate property — up to half of it.
Section 21611 gives three ways around this. Your spouse won’t count as omitted if:
- Your will or trust clearly says the omission was on purpose.
- You provided for your spouse some other way — through life insurance, a trust, or a big gift outside the will.
- Your spouse signed a valid waiver, like a prenup.
The takeaway is simple. If you want to leave your spouse out, say it out loud in the document. Do not rely on silence. California courts treat silence as an accident.
Four Real-Life Situations
Different reasons, different strategies. Here are the most common ones.
The second marriage. You remarried in your sixties and want most of your assets to go to your adult children from the first marriage. The clean path is a prenup signed before the wedding that waives your new spouse’s inheritance rights to your separate property, paired with a clearly drafted trust.
The long separation. You’ve been separated for a decade but never filed for divorce. Without a formal legal separation judgment, your spouse is still legally your spouse. They still have full community property rights. The fix is either to finalize the divorce or get a formal property settlement.
The business owner. You want your half of the company to pass to a business partner or to your kids. Without planning, your spouse becomes a 50% owner of your share of the company the day you die. A buy-sell agreement paired with a trust is the usual solution.
The family money. Your parents left you money or property, and you want it to stay in your bloodline. Good news — inheritances are separate property in California. As long as you never mixed those funds with community money, you can leave them wherever you like.
How to Actually Do It
If you are thinking about this in California, here is the short list.
- Talk to a California estate planning attorney. This is not a DIY project. Community property rules get messy fast, and one wrong word can hand your spouse everything.
- Be explicit in writing. Name your spouse. State that the omission is intentional. Vague language is how cases get contested.
- Consider a prenup or postnup. This is the strongest tool California offers for limiting spousal inheritance.
- Update beneficiary forms. Your 401(k), IRA, and life insurance policies pass by beneficiary designation, not by will. Make sure they match your plan.
- Fund your trust. Retitle your house, accounts, and brokerage holdings into the trust’s name. An unfunded trust controls nothing.
- Add a no-contest clause. California honors these, within limits. It discourages a spouse from fighting the will just to see what sticks.
None of these steps is dramatic. But together they are the difference between a plan that holds up and a plan that collapses.
The Bottom Line
Can you disinherit a spouse in California? Partly. You can leave your half of community property and all of your separate property to someone else. What you cannot do is touch your spouse’s half of community property, because that half was never yours.
The real lesson from the sections above: California does not punish you for wanting to protect your children, your business, or your family money. It just insists you do it deliberately — in writing, with the right tools, and ideally with your spouse’s signed agreement on the big stuff.
What to do this week: pull out your current will or trust. Find the part about your spouse. If it says nothing, or if it’s ambiguous, book a 30-minute consultation with a California estate planning attorney. That conversation is the cheapest and most important step in this whole guide.
FAQ Section
Can I completely disinherit my spouse in California?
No. California’s community property law under Family Code section 760 gives your spouse a 50% stake in everything earned during the marriage. You can cut them out of your half and your separate property, but their half is theirs by law.
What happens if I just leave my spouse out of my will without explaining?
They will probably still inherit. Under California Probate Code section 21610, a spouse omitted from the will is presumed to be left out by accident. To actually disinherit them, your will must explicitly say the omission was intentional.
Does a prenup really waive spousal inheritance rights in California?
Yes, if done correctly. Under California Family Code section 1615, both people must sign voluntarily, exchange full financial disclosures, and have the chance to use their own attorney. A rushed or unfair prenup can be thrown out later.
What about my separate property — like money I had before the marriage?
Separate property is yours to give away however you choose. This includes assets you owned before marriage, inheritances you received, and gifts made directly to you. Just do not commingle these funds with community property, or they may lose their separate status.
Can my spouse still challenge my will even if I explicitly disinherit them?
Yes. A spouse can challenge a will for reasons like undue influence, lack of mental capacity, or forgery. California also gives beneficiaries 120 days from a trustee’s notice to file a trust contest. A no-contest clause discourages weak challenges but does not block legitimate ones.
