How to Update Your Will

Your guide to updating a Will: codicils vs starting fresh, the life changes that should prompt a review, and handling digital assets.

Last updated: 15 March 2026

Why Wills Go Out of Date

Your Will captures your life as it stood on the day you signed it. The problem is that life keeps moving. You wrote it when the kids were small and you lived in a semi in Reading. Now the kids have grown up, you've moved twice, divorced once, remarried, and your financial picture looks completely different. The Will sitting in your filing cabinet still thinks it's 2015.

Outdated Wills cause real problems at probate. Beneficiaries who've fallen out of your life still inherit. Executors who've moved to Australia are expected to manage things from 10,000 miles away. Property you sold years ago is still listed as a specific gift. And if you've married since making the Will, there's a strong chance the document was automatically revoked without you realising.


Life Events That Should Trigger a Review

Some changes in your circumstances have direct legal consequences for your Will. Others just mean the document no longer reflects what you'd actually want. Both are good reasons to revisit it.

Marriage is the big one. In England and Wales, getting married automatically cancels every Will you previously made. It doesn't matter how recently you wrote it or how comprehensive it was. The moment you sign the register, the old Will is void. If you die after marrying without making a new Will, intestacy rules take over.

The only exception is a Will that was drafted "in contemplation of" that specific marriage, meaning the solicitor or service wrote it with that particular wedding in mind. That's fairly rare.

Divorce doesn't cancel your Will outright, but it removes your ex-spouse from any role as beneficiary or executor. The rest of the document survives. Most Wills are written with the partner as the main beneficiary, so removing that person leaves gaps the remaining clauses were never designed to cover. Writing a new Will after divorce is not something to put off. It needs doing straight away.

Children arriving changes priorities. Your existing Will might leave everything to your partner, which may have been fine when it was just the two of you. Now there are children to think about, and potentially guardians to name.

Bereavement matters too. If someone named in your Will, whether as beneficiary, executor, or guardian, has since died, the provision that relates to them may fail. Some Wills include substitute clauses that cover this automatically, but many don't.

Property changes can affect specific gifts. Sold the house you left to your daughter? That gift no longer has anything to attach to. Bought a new property? It falls into the residuary estate unless you specifically add it.

Financial shifts of any real size warrant a review. An inheritance, a redundancy payout, a business sale, or a significant debt all change what your estate looks like and how it should be distributed.


Codicil vs New Will

When you want to change your Will, you've got two options.

A codicil works like a formal correction slip attached to your current Will. You write out the amendment, have two witnesses present while you sign it (the same witnessing rules apply), and store it with the original Will. Everything in the original remains valid apart from the specific clauses you have amended.

It's the right tool when you're making small fixes: swapping an executor, adjusting a percentage split, adding a legacy to a grandchild. If the bones of your Will are still right and you're only nudging a detail, a codicil keeps things simple.

Bigger shifts call for a completely fresh Will. The new document includes a revocation clause that wipes the old one out, so there's never any doubt about which version applies. Marriage, divorce, a major restructure of the estate: these are all "start again" situations.

A word of caution. Piling codicil on top of codicil is a classic error. Three amendments stapled to a fifteen-year-old Will turns into a paperwork maze that nobody wants to untangle during probate. One codicil? Fine. Two or more? Just write a new Will. It takes roughly the same amount of time, and you end up with one clean document instead of a patchwork.


Can You Edit a Will After Signing It?

No. You might be thinking about crossing out a name with a pen, writing a replacement in the margin, or sticking a note to the page with updated instructions. None of that works. Handwritten changes carry zero legal weight and, worse, they make the document look tampered with, which can invite a challenge at probate.

The two legitimate options are a properly witnessed codicil or a brand-new Will. No middle ground exists.


How Often Should You Review?

No law says you must review your Will by a certain date, but three to five years is the interval most professionals would recommend. Small things accumulate without you noticing. Your executor retired and moved to the Algarve. Your pension pot doubled. A friendship that felt solid five years ago has drifted apart. Sitting down with the document every few years lets you spot these changes before they create real problems during probate.

Marriage, divorce, a new baby, a death, or a big financial change won't wait for your next scheduled check. When one of those lands, pull the Will out and read it within the month.


Need a fresh start?

Sometimes it is easier to write a new Will than add a codicil. Our online service makes starting again quick and painless.

What About Digital Assets?

This is an area that's changed enormously since most existing Wills were written. Your estate now probably includes email accounts, social media profiles, digital photo libraries, cryptocurrency wallets, online business accounts, and subscription services.

While the law around digital assets is still evolving, you can include preferences in your Will about what happens to these accounts. Some people name a "digital executor" with login credentials stored separately. Others simply note which accounts exist so their executors know where to start.

If you made your Will before you had significant digital assets, that alone is worth a revisit.


The Process of Updating

If you used a solicitor originally, you can go back to them for updates. They'll have a copy of the original and can advise on whether a codicil or new Will makes more sense.

Online services generally let you create a replacement Will through the same platform, often with your earlier answers pre-loaded so you don't have to start from a blank screen.

Whichever route you take, destroy the old Will once the replacement is properly signed and stored. Physically shred it. Leaving multiple versions in circulation is a recipe for confusion at probate. Physically destroy the old Will and every copy of it, then tell your executors where the replacement is stored.


Next Steps

When did you last actually read through your Will? Have you married, split up, or had a child since it was written? Either of those is reason enough to act. Our online tool lets you build a replacement Will from scratch in about fifteen to twenty minutes, and your executors will thank you for keeping things current.

Frequently Asked Questions

Does getting married cancel my existing Will?

Yes. In England and Wales, marriage automatically revokes any Will you previously made, unless the Will was specifically drafted in contemplation of that particular marriage. If you marry without making a new Will, intestacy rules apply.

What is a codicil and when should I use one?

A codicil is a formal amendment to your existing Will. It must be signed and witnessed using the same rules as the Will itself. It's suitable for small changes like swapping an executor or adjusting a percentage split. For larger changes, writing a new Will is usually better.

Can I just cross out parts of my Will and write in changes?

No. Handwritten amendments to a signed Will have no legal effect and can make the document look tampered with, potentially inviting a challenge at probate. The only valid options are a properly witnessed codicil or a completely new Will.

How often should I review my Will?

Most professionals recommend reviewing your Will every three to five years, even if nothing major has changed. You should also review it immediately after significant life events such as marriage, divorce, the birth of a child, bereavement, or major financial changes.

Should I include digital assets in my Will?

It's a good idea. Your estate likely includes email accounts, social media profiles, cryptocurrency, and online subscriptions. While the law is still evolving, you can include preferences about what happens to these accounts and name someone to manage them.
