When to Update a Will
Your will isn't a one-time document. Life changes. Your circumstances shift. That's when you need to update old will documents to reflect your current situation.
The most common triggers are straightforward. Marriage or civil partnership means you need to revisit your wishes. The birth of children or grandchildren changes who you want to protect. Significant changes in your finances, whether you've bought property, inherited money, or built a business, require updating. Equally, if your relationships have changed, a will update becomes essential.
According to the Law Society's guidance on wills and estate planning, failing to update your will when circumstances change can lead to unintended consequences for your loved ones. What worked ten years ago may not serve your family today.
Updating your old will is simpler than you might think, and it gives you genuine peace of mind.
Will Changes After Marriage: What You Must Know
Marriage or civil partnership automatically affects your will. This is one area where the law steps in with clear rules that catch many people off guard.
When you marry or enter a civil partnership, your previous will is automatically revoked. That means if you had a will before the marriage, it's no longer valid. Your estate would be distributed according to the intestacy rules instead, which rarely reflects what people actually want.
This doesn't mean you need to panic. It means you need to act. Creating a new will after marriage ensures your spouse is protected and your wishes are documented. If you want to leave anything to children from previous relationships, a new will becomes even more critical.
The UK legislation on wills and intestacy sets out exactly how estates are distributed when there's no valid will in place. Without a current will, your spouse might inherit less than you'd intended, and other family members could be overlooked entirely.
Codicil vs New Will: Which Option Is Right for You
When you need to update old will arrangements, you have two paths forward. Understanding the difference between a codicil and a new will helps you choose the right approach for your situation.
A codicil is a legal amendment to your existing will. It's a separate document that changes specific parts of your original will without replacing the whole thing. Codicils work well for minor changes: updating an executor's name, adjusting a small bequest, or adding a new beneficiary for a specific item.
A new will replaces your old will entirely. It's a fresh document that sets out your complete wishes from scratch. A new will is clearer, simpler to execute, and less likely to create confusion later. For most people updating their arrangements, a new will is the better choice.
The key difference comes down to complexity and clarity. If you're making one or two small adjustments, a codicil is efficient. If your circumstances have changed significantly, new family members, different financial situation, changed priorities, a new will removes ambiguity and makes your intentions crystal clear to your executors and beneficiaries.
| Approach | Best For | Complexity | Clarity |
|---|---|---|---|
| Codicil | One or two minor changes | Simple | Can create confusion if multiple codicils exist |
| New Will | Significant life changes or multiple updates | Straightforward | Completely clear and unambiguous |
How to Make a Will Legally Valid When Updating
Your updated will must meet strict legal requirements. Get this wrong and your will could be challenged or declared invalid, leaving your family in uncertainty.
A valid will in the UK requires several elements. It must be in writing, handwritten or typed. You must have mental capacity: you need to understand what you own, who might reasonably expect to benefit, and the practical effect of the will you're creating.
The witnesses cannot be beneficiaries or married to beneficiaries. This is a common mistake. If a witness stands to inherit under your will, the entire will can be invalidated. Your witnesses must be independent, impartial people aged 18 or over.
The UK Courts and Tribunals Judiciary provides official guidance on will validity requirements. Following these requirements precisely protects your will from challenge and ensures your wishes are carried out exactly as you intend.
Many people think they can simply update their old will by hand or add notes to the existing document. This creates legal chaos. Your executors won't know which version is current. Beneficiaries might argue over your intentions. Courts might have to intervene.
Documents You'll Need to Gather
Before you start the updating process, gather your key documents. Having everything in one place makes the process smoother and ensures you don't miss anything important.
Start with your current will. Read it carefully. Understand what it says and what you want to change. Locate your marriage or civil partnership certificate if you've married since your last will.
Gather details about your assets:
- Property deeds or evidence of ownership
- Bank account statements
- Investment and pension statements
- Life insurance policies
- Business ownership documents if applicable
List your potential beneficiaries and executors. Write down who you want to benefit and who you'd trust to carry out your wishes. If you have minor children, note who you'd want as their legal guardians.
Collect any previous correspondence with solicitors or estate planning professionals. If you've had advice before, understanding that context helps.
Having these documents organised before you meet with a professional saves time and ensures nothing gets overlooked.
Step-by-Step Process for Updating Your Old Will
Step 1: Review Your Current Will
Start by reading your existing will carefully. Understand exactly what it says and what you want to change. Many people realise their old will no longer reflects their wishes once they actually review it.
Note the specific sections you want to modify. Are you changing beneficiaries? Updating your executor? Adding new provisions? Being clear about what needs to change makes the next steps straightforward.
Step 2: Identify What Needs to Change
Write down the specific changes you want to make. Be precise. Instead of vague thoughts like "update my arrangements," write clear statements: "I want to leave £5,000 to my grandson" or "I want to appoint my daughter as executor instead of my brother."
List any new circumstances that affect your will. Marriage, children, significant financial changes, changes in your relationships, these all matter. Your updated will should reflect your current life, not your life from ten years ago. Complex asset structures or evolving family dynamics often necessitate a broader evaluation of the living trust vs will to ensure that your chosen method of distribution remains the most effective way to protect your legacy.
Step 3: Decide Between a Codicil and a New Will
Evaluate whether you need a codicil or a new will. As discussed earlier, most situations benefit from a new will. If you're making multiple changes or if your circumstances have changed significantly, a new will provides complete clarity.
A codicil works only if you're making one or two straightforward amendments to an otherwise still-current will. Even then, many professionals recommend a new will because it's clearer and less likely to create confusion.
Step 4: Draft Your Changes or Replacement Will
Write out your new will or codicil. Be clear and specific. Avoid vague language. Instead of "I want my children to be looked after," write "I appoint [Name] as guardian for my children until they reach 18."
Use plain English. Avoid legal jargon where possible. Your will should be understandable to your family, not just to lawyers. If you're uncertain about wording, professional guidance ensures your wishes are expressed correctly.
Step 5: Ensure Proper Execution and Witnessing
This step is critical. Your will must be signed correctly or it won't be valid.
Sign your will in the presence of two independent witnesses. Both witnesses must watch you sign. Then you must watch both witnesses sign. All three signatures must happen in the same room, at the same time.
Your witnesses cannot be beneficiaries or married to beneficiaries. They should be people you trust to be available if needed later. Many people choose friends, colleagues, or neighbours.
Date your will. Write the date clearly at the bottom. This helps establish which version is current if multiple versions exist.
Keep your original signed will in a safe place. Many people store it with a solicitor, in a bank safety deposit box, or with their executor. Tell your executor where it's kept.
Common Mistakes to Avoid When Updating Your Old Will
People make predictable errors when updating their wills. Knowing these mistakes helps you avoid them.
Failing to revoke the old will clearly. If you're creating a new will, make sure it includes a clear statement revoking all previous wills.
Not updating after major life events. Marriage automatically revokes your previous will. If you marry and don't create a new will, you die intestate.
Choosing the wrong witnesses. Using a beneficiary as a witness invalidates their gift under the will. Using a spouse of a beneficiary creates the same problem.
Making handwritten changes to an existing will. Crossing out text or writing notes in the margins doesn't legally update your will.
Assuming an old will still works. Circumstances change. What made sense ten years ago might not serve your family now.
Updating your old will ensures your wishes are documented and your family is protected.

Frequently Asked Questions
How do I know if my old will is still legally valid?
Your existing will remains valid unless it was revoked or affected by a significant life event. Marriage automatically revokes a previous will under English law unless it was made in contemplation of that marriage. Divorce does not revoke a will but can affect its provisions. If you're unsure whether your will is still valid or appropriate for your current circumstances, a review by a qualified professional is advisable to ensure it still reflects your wishes and protects your family properly.
Can I update my will with just a codicil, or do I need to write a new will?
A codicil works well for minor, straightforward changes such as updating an executor or adjusting a specific bequest. However, if you're making multiple changes, altering the overall structure of your estate plan, or if your circumstances have changed significantly, a new will is often clearer and easier to manage. A new will also avoids confusion and potential disputes among beneficiaries. For complex updates, particularly involving property or family changes, a fresh will provides better clarity and legal certainty.
What happens if I don't update my will after getting married?
Marriage automatically revokes your previous will under English law, unless that will was specifically made in contemplation of the marriage. This means if you die without updating your will after marriage, your estate may be distributed according to intestacy rules rather than your original wishes. Your spouse will have rights to a portion of your estate, but your children or other beneficiaries may not inherit as you intended. Updating your will after marriage is essential to ensure your new spouse and any other beneficiaries are properly provided for.
How do I ensure changes to my will are legally binding?
Whether using a codicil or a new will, legal validity requires specific formalities. Your document must be in writing, signed by you in the presence of two independent witnesses who are both present at the same time, and each witness must also sign. The witnesses cannot be beneficiaries or married to beneficiaries. Your signature and the witnesses' signatures must appear on the same page or be acknowledged on that page. Following these requirements precisely ensures your will is legally enforceable and your wishes are properly carried out.
