Updating Your Will After Marriage, Divorce, or a New Child in NY

If you have married, divorced, or welcomed a new child in New York, the short answer is yes: you should update your will, and doing so is more straightforward than most people fear. A will written before a major life change may no longer say what you want it to say, and in some cases New York law will adjust your will for you in ways you may not expect. The good news is that updating a will does not mean starting from scratch. With a few clear steps, you can make sure the people you love are protected. This guide walks you through the essentials, the parts everyone should understand, in plain language and with reassurance that this is a normal, manageable part of life planning.

A will is simply a legal document that says who receives your property and who manages your estate after you pass away. It only takes effect at death, and it must be filed with the Surrogate’s Court in a process called probate. (A “living will” is a completely different document about health-care wishes while you are alive, so do not confuse the two.) When your family changes, your will should change with it.

Why Life Changes Trigger a Will Update

New York law does not freeze your will in time. Certain events have legal consequences whether or not you take action, which is exactly why being proactive matters.

After You Marry

When you marry, your new spouse gains important legal protections under New York law. Under the spousal right of election (EPTL 5-1.1-A), a surviving spouse can claim a minimum share of your estate, generally the greater of $50,000 or one-third of the net estate, even if your will leaves them less or nothing at all. If your old will was written before the marriage and does not mention your spouse, the law steps in to protect them, but the result may not match what you actually intend. Updating your will lets you decide the details yourself rather than leaving them to a statutory formula.

After You Divorce

Divorce is one of the most important times to revisit your will. In New York, a final divorce generally revokes any gifts to your former spouse and removes them as executor, as if they had predeceased you. That sounds protective, and it often is, but it can leave gaps. For example, if your ex-spouse was your named executor and sole beneficiary, who steps in now? Without an update, parts of your estate could pass in ways you never planned. A clean, current will removes the guesswork.

After a New Child Arrives

A new child, whether by birth or adoption, is a joyful reason to update your will. New York protects “after-born” children who are not provided for in a will, but the protections are limited and may not reflect your wishes. More importantly, a will is where you name a guardian for your minor children, one of the most important decisions a parent can make. You can also set up how and when your child inherits, so that assets are managed responsibly until they are old enough.

Update or Replace? Two Simple Paths

Many first-timers assume updating a will is complicated. It is not. There are two common, well-established approaches:

Approach	Best for	How it works
Codicil	Small, targeted changes (e.g., changing one beneficiary or executor)	A short legal amendment that attaches to your existing will
New will	Multiple changes, marriage, divorce, or a new child	A fresh will that revokes the old one entirely

A codicil is an amendment to an existing will. It is useful for a single, simple change. However, a codicil must be signed and witnessed with the same formalities as a will, so it is not a casual edit. When life changes significantly, drafting a brand-new will is often cleaner and less prone to confusion. Learn more on our codicils and amendments page and our will drafting overview.

The Formalities Still Apply

Whichever path you choose, your updated will (or codicil) must be executed correctly to be valid. New York’s execution requirements are set out in EPTL §3-2.1, and they are precise. Getting them right is what makes the document legally enforceable.

• You need at least two attesting witnesses.
• Both witnesses must sign within one 30-day period (the law presumes this requirement is met, a rebuttable presumption).
• You, the testator, must sign at the end of the will (or direct another person to sign for you, in your presence).
• You must declare the document to be your will, a step called publication.
• You must sign in front of the witnesses, or acknowledge your signature to each of them.
• The witnesses sign at your request and add their residence addresses.

Because these steps are exact, a do-it-yourself update is risky. A small mistake, such as a missing signature or an improperly witnessed page, can invalidate the whole document. For a full breakdown, see our pages on NY will requirements and will execution.

What Happens If You Don’t Update

If you pass away without a valid will, or with a will that no longer reflects your life, New York’s intestacy rules under EPTL Article 4 decide who inherits. These rules distribute your property to your closest next of kin in a fixed order set by statute. That may mean a new spouse, a stepchild you intended to provide for, or a charity you cared about receives nothing, simply because the law followed its own formula. You can read more on our intestacy: dying with no will page. Keeping your will current is how you keep control.

A Simple Checklist When Your Family Changes

1. Locate your current will and read it with fresh eyes.
2. List what changed (spouse, ex-spouse, new child, new guardian needs).
3. Decide: codicil or new will, ideally with an attorney’s guidance.
4. Name or update your executor and guardians.
5. Execute the document properly under EPTL §3-2.1.
6. Store it safely and tell your executor where to find it.

Frequently Asked Questions

Do I have to rewrite my whole will after marriage?
Not necessarily. A codicil can handle a single small change, but marriage often affects several provisions and triggers your spouse’s right of election under EPTL 5-1.1-A, so a new will is frequently the cleaner choice.

Does divorce automatically remove my ex from my will in New York?
Generally, a final divorce revokes gifts to a former spouse and their appointment as executor, treating them as if they predeceased you. But this can leave gaps, so you should still update your will to fill them.

What happens to a child born after I signed my will?
New York provides limited protection for “after-born” children, but it may not match your wishes. Updating your will lets you provide for the child clearly and name a guardian.

Is a “living will” the same as updating my will?
No. A living will is a health-care document about end-of-life wishes while you are alive. A property will, which only takes effect at death and goes through Surrogate’s Court, is what you update after marriage, divorce, or a new child. See our living will page to understand the difference.
