To update a will after a divorce is one of the smartest steps you can take once the paperwork is final. Your will is a legal instrument that says who gets your property and who manages your estate when you die. During your marriage, it likely named your spouse as the main heir and the executor — the person who settles your estate.
After a split, those wishes usually change. Many states have a law that quietly rewrites part of your will for you, but that safety net has holes. As a result, the surest way to protect your family is to sit down and update a will after a divorce yourself, on purpose.
What the Law Already Does for You
More than 40 states have a “revocation upon divorce” law. It is based on the Uniform Probate Code, Section 2-804. In plain terms, once your divorce is final, the law treats your ex-spouse as if they died before you. Their gift in your will is cancelled. Their role as executor is cancelled too. The property then passes as if your former spouse had not survived you.
For example, California Probate Code Section 6122 revokes any gift to a former spouse and any provision naming them as executor, trustee, or guardian. Texas Estates Code Section 123.001 does the same. It reads the whole will as if the ex-spouse “failed to survive.” Both laws include one interesting twist. If you later remarry the same person, the revoked gifts spring back to life.
However, these laws only kick in after a full divorce or annulment. A legal separation does not count. If you are separated but not divorced, your spouse is still your spouse under the will. That is a common and costly surprise.
Why You Still Need to Update a Will After a Divorce
The state law is a backstop, not a fix. It leaves gaps, and those gaps cause real fights. In most cases you should still update a will after a divorce for three reasons.
First, retirement accounts and life insurance often ignore state law. Federal law called ERISA controls 401(k) plans, pensions, and many workplace policies. ERISA says the beneficiary form on file wins — even over a divorce decree. So your ex could still collect your entire 401(k) unless you change the form yourself. Typically you should update these designations within 30 days of the decree.
Second, the law only removes your ex. It does not name a new heir or a new executor. Without a fresh plan, that share may pass under your state’s intestate rules — the default law for people with no valid will for that gift. You may not like where it lands.
| Document | Does divorce fix it automatically? | Your action |
|---|---|---|
| Will (gift to ex) | Usually yes — treated as predeceased | Rewrite to name new heirs |
| Executor named (ex) | Usually yes — appointment revoked | Name a new executor |
| 401(k), pension (ERISA) | No — federal law controls | File a new beneficiary form |
| Life insurance | Varies by state and policy | Update the beneficiary |
| Legal separation only | No — spouse still counts | Wait or make a new will |
Third, courts can apply these laws in ways you did not expect. In 2018, the U.S. Supreme Court in Sveen v. Melin upheld a revocation-on-divorce law even for a policy bought before the law existed. The lesson is simple. Do not rely on guesswork. Take control and update a will after a divorce with your own clear choices.
How to Update a Will After a Divorce, Step by Step
The process is calmer than it sounds. You do not need to fear it. Here is a plain path many families can follow.
Start by making a fresh will rather than crossing out lines on the old one. Handwritten edits can void the whole document. A new will typically must be signed in front of two witnesses — that number is standard in most states, including California and Texas. Some states also let you notarize a short statement so the will proves itself in court faster.

Next, name your new executor and your new heirs. Decide who receives specific gifts. If you leave property to your children, consider whether you want it split “per stirpes.” That Latin term simply means each branch of the family takes its share, so a deceased child’s portion flows down to that child’s kids. Finally, change your beneficiary forms on every retirement account, life insurance policy, and payable-on-death bank account. When you update a will after a divorce, treat those forms as part of the same job.
Frequently Asked Questions
Does my divorce automatically remove my ex from my will?
In most cases, yes. Over 40 states cancel gifts and executor roles for a former spouse once the divorce is final. However, this does not apply to a legal separation, and it does not cover ERISA retirement plans.
Do I have to make a brand-new will, or can I edit the old one?
A fresh will is usually safest. Crossing out names by hand can accidentally void the document. For example, a clean new will signed before two witnesses removes any doubt about your true wishes.
What happens to my 401(k) if I forget to change the form?
Federal ERISA law says the named beneficiary controls. As a result, your ex-spouse could still inherit the account even after divorce. Typically you should file a new beneficiary form right away, or check with your state’s court or a licensed attorney.
Make Sure Your Plan Actually Works
A will or trust only does its job if the rest of your plan lines up. Two quick checks before you finish:
- Get your state’s exact rules — witnesses, notary, probate cost, and tax thresholds vary by state.
- Beneficiary forms beat your will — make sure your life-insurance beneficiaries are current, because named beneficiaries pass outside your will.
