You might assume your will still reflects your life, until something changes: a new home, a new grandchild, a separation, or a new person you trust to act as executor. If you update it the wrong way, you can create confusion for your family and delays during probate. In this guide, we walk you through The Legal Process for Amending Your Will: Step-by-Step Guide, so you can make changes clearly, legally, and with confidence.
Key Takeaways
Amending your will legally requires either a codicil for small changes or a new will for major updates, ensuring clarity and validity.
Review your will after significant life events like marriage, divorce, or property changes to keep it current and effective.
Always sign your will amendments with two independent witnesses present to avoid invalidity or disputes.
Preparing a clear asset list and confirming executor and trustee appointments beforehand simplifies the amendment process.
Seek professional advice for complex situations involving trusts, blended families, tax planning, or potential disputes.
Store your updated will securely and inform your executors of its location to ensure it can be easily found when needed.lick on this text to edit it.

When You Should Amend Your Will (And What Changes Trigger It)
A will can look "fine" for years, and then one life event makes it outdated overnight. If you wait until you are unwell or under pressure, you increase the risk of errors, capacity challenges, or a document that no longer matches what you own and who you want to benefit.
In practice, you should review your will after any of these common triggers:
Marriage or civil partnership: in England and Wales, marriage can revoke an existing will unless it was made in contemplation of that marriage. That can leave you unintentionally intestate.
Divorce or dissolution: divorce does not automatically revoke your entire will, but it can treat certain gifts to an ex-spouse (and their appointment as executor) as if they had died. That can break the structure of your estate plan.
Children, stepchildren, or grandchildren: you may want to add guardianship provisions for minors, update trusts, or reflect changing family needs.
Buying or selling property: if your will deals with "my home at [address]", moving house can create ambiguity. Even if your will uses broader wording, your estate value and distribution may now be very different.
A significant change in assets: for example, a new business interest, a large investment account, or an inheritance you did not expect.
A change in your executors or trustees: if your chosen executor has died, moved abroad, become unwell, or you no longer trust them, you should act quickly.
Changes in relationships or risk: second marriages, estrangement, or a vulnerable beneficiary (for example, someone with addiction or financial difficulties) can justify more careful planning.
A useful rule of thumb: if the change affects who inherits, who manages the estate, or how your estate is taxed or protected, it is time to consider a formal amendment. Where inheritance tax could be relevant, it can also help to align your will changes with wider estate planning, such as inheritance tax planning support that looks at allowances, gifting, and longer-term strategy.
If you are unsure, we usually suggest a quick "life admin" review every two to three years, even if nothing major has happened. You often catch small issues before they become expensive ones.
Before You Start: Check Your Current Will, Assets, And Executors
People often start amending a will by focusing on the change they want ("I need to add my grandson"), but miss the knock-on effect ("Does that change the residue? Does it affect a trust? Have I named the right executors?"). A short audit before you draft anything can save you from rewriting the document twice.
Start with your current will and any codicils. You need to confirm:
Which document is the latest (and whether older wills were properly revoked).
Whether there are any codicils already in place. Multiple codicils can work, but they raise the risk of inconsistency.
How gifts are structured: specific gifts (like "my car"), cash gifts (legacies), and the residuary estate (what is left after debts and gifts).
Then build a simple, practical asset list. You do not need a forensic spreadsheet, but you do need enough detail to make sure your will fits your real life:
Property: addresses, ownership type (joint tenants or tenants in common), and approximate value.
Bank and savings: major accounts and where they are held.
Pensions and life assurance: note that these often pass by nomination rather than the will, so check beneficiaries.
Business assets: shares in a limited company, partnership interests, or sole trader value.
Digital assets: online accounts, crypto holdings, or monetised content. Even if you do not pass them through the will, you should make it easy for executors to locate them: a dedicated inventory helps (this can sit outside the will for privacy). The approach is similar to the one we discuss in our guidance on building a digital assets inventory for estate planning.
Finally, sanity-check your appointments:
Executors: choose people who are organised, willing, and likely to outlive you. Many people appoint two, with a substitute.
Trustees (if your will includes trusts): these roles carry ongoing responsibilities, so capacity and reliability matter.
Guardians: if you have children under 18, confirm your proposed guardian is still appropriate and has agreed.
If you do this preparation first, the legal drafting becomes far more straightforward, and you reduce the risk of leaving gaps that lead to disputes later.
The Two Legal Routes: Codicil Vs Making A New Will
A common (and risky) scenario is someone taking a pen to the signed will and "just changing a name". That feels simple, but it is not how UK law expects you to amend a will. In most cases, you have two proper routes: a codicil or a new will.
Codicil: best for small, specific changes
A codicil is a separate legal document that amends your existing will. It must be signed and witnessed with the same formalities as a will.
A codicil can be suitable when you are making limited changes such as:
changing an executor (for example, replacing someone who has died)
updating a small cash gift (like changing £2,000 to £5,000)
correcting a straightforward error (such as an address)
The benefit is that it is often quicker and cheaper. The downside is that codicils stack. If you already have one codicil and you are now making another, you can end up with a paper trail that is harder for executors to interpret.
New will: best for major or multiple changes
A new will is usually the right option when:
you want to change several gifts or restructure who receives the residue
you are adding trust provisions (for minors, vulnerable beneficiaries, or tax planning)
your family situation has changed significantly (remarriage, blended families, estrangement)
you have had changes in property ownership or new overseas assets
A properly drafted new will should include a clear clause revoking previous wills and codicils. That prevents two documents pulling in different directions.
If you are already thinking, "This is getting complicated," that is often your cue to stop trying to patch an old document and consider a clean rewrite. It is also where a specialist will writer can help you align the will with related planning, such as trust advice and support where a trust structure is genuinely appropriate.
Either way, the legal standard is the same: the document must be clear, correctly executed, and easy for your executors to rely on when you are no longer here to explain it.
How To Amend Your Will Step By Step (From Drafting To Witnessing)
Most invalid amendments happen because someone rushes the process and misses a formality. The safest approach is to treat the amendment like a mini legal project: define the change, choose the right document, execute it properly, and store it so it can be found.
Step 1: Write down the change in plain English
Start with one paragraph that states what you want to happen, using names and relationships:
"I want to remove my brother, James Patel, as executor and appoint my daughter, Priya Patel."
"I want to leave £10,000 to my niece, Amelia Jones, of [town], and reduce my residuary estate accordingly."
This step matters because unclear instructions produce unclear drafting.
Step 2: Decide codicil or new will
Use a simple decision test:
One small change with no knock-on effects: a codicil may work.
More than one change, or any change to residue or trusts: a new will usually makes more sense.
If you have any doubt, assume a new will is safer. It reduces the risk of conflict between documents.
Step 3: Draft the document carefully
If you use a professional, they will draft in formal language and check for internal consistency. If you draft yourself (not usually recommended), you need to be precise:
identify the original will by date
state exactly what clause you are changing
write the replacement clause in full
Avoid vague phrases like "I want to share things fairly" because an executor cannot apply "fair" without a defined method.
Step 4: Check capacity and remove pressure
A challenge to a will often focuses on whether you had mental capacity or whether someone influenced you. If you are older, unwell, or have a diagnosis that could later be questioned, take practical steps:
sign when you feel well and are not under medication that affects decision-making
keep a short written note (or professional attendance note) explaining why you made the change
consider a GP capacity letter in higher-risk cases (this is not always necessary, but it can help)
If you are already thinking about decision-making support for later life, it may also be a good time to consider setting up lasting powers of attorney so the people you trust can act if needed.
Step 5: Sign and witness correctly (this is where people slip)
For a will or codicil in England and Wales, you usually need:
your signature (or someone signing on your behalf at your direction)
two witnesses, present at the same time
the witnesses to sign in your presence
Choose witnesses who are:
over 18
independent (not beneficiaries and not married to a beneficiary)
able to attend together and follow the process
A practical example: if your neighbour is a witness and your neighbour's spouse is a beneficiary, that creates problems. Keep it clean.
Step 6: Attach and reference correctly (if relevant)
If you have schedules or supporting notes, you must handle them properly. As a rule, do not "staple a list" to a will and assume it becomes part of it. If you need to reference an external document, get proper advice on how to do it safely.
Step 7: Store the final, signed version and tell the right people
The amendment only helps if it can be found. Store it securely, keep it together with the will it amends, and let your executors know where it is (more on storage later).
This step-by-step approach is the practical heart of The Legal Process for Amending Your Will: Step-by-Step Guide: a valid document, correctly executed, that your family can rely on without second-guessing what you meant.
Common Mistakes That Make Amendments Invalid (Including Handwritten Changes)
If your family ends up arguing over your estate, it is often because the paperwork leaves room for doubt. Many disputes start with good intentions: someone tries to "tidy up" the will themselves, or makes a change without realising that the legal formality is the whole point.
Here are the mistakes we see most often, and what to do instead.
Handwritten changes on the signed will
Crossing out a name, writing in a new amount, or adding a note in the margin can be fatal to clarity. Even if a court accepts that you wrote it, it can still create ambiguity and trigger arguments.
Do instead: use a codicil or a new will, signed and witnessed properly.
3. Witness problems (beneficiaries, spouses, or missing witnesses)
If a beneficiary witnesses the will, the gift to that witness can fail. If you only use one witness, the document may be invalid. If witnesses are not both present at the time of signing, you create risk.
Do instead: pick two independent witnesses who do not benefit under the will.
4. Trying to change the will by letter, email, or a "side note"
People sometimes leave a letter with the will that says "ignore clause 5" or "I want my jewellery to go to…". That might feel helpful, but it is usually not legally effective.
Do instead: put the gift into the will or codicil, or use a non-binding memorandum only where appropriate and properly drafted.
5. Conflicting documents (multiple codicils and unclear revocation)
A common mess looks like this: will (2012), codicil (2018), codicil (2020), and then a half-finished draft (2024) kept in a drawer. Executors then have to work out what is valid and what is not.
Do instead: if there are multiple changes, replace the whole document with one new will and revoke prior documents clearly.
6. Invalid or unclear gifts
You can unintentionally create an invalid clause by being too informal, for example:
"I leave my house to my children" (which house, if you move?)
"I leave £5,000 to my friend John" (which John?)
"I leave my business to my son" (what if the business structure changes?)
Some clauses are problematic because the law treats them as uncertain or ineffective. If you want a sense of how these issues arise, our guidance on examples of invalid will provisions and why they fail is a useful reference point.
The practical fix is almost always the same: use clear identifiers, avoid assumptions about future assets, and make sure the execution is beyond question.
Do You Need A Solicitor? When Professional Help Is Advisable (And When It May Not Be)
A lot of people hesitate because they think, "Surely I can just do this myself," and they worry professional help means high fees and a drawn-out process. The truth is more balanced: some amendments are genuinely straightforward, and others are only "simple" until you see the risks.
When professional help is advisable
You should strongly consider a solicitor or specialist will writer (with appropriate support) when any of the following apply:
Blended families: you want to provide for a partner but protect children from a previous relationship.
Trusts: minors, vulnerable beneficiaries, discretionary trusts, or life interest arrangements.
Inheritance tax planning: the will interacts with allowances, gifts, and wider planning.
Business or agricultural assets: reliefs, succession planning, and control issues.
Overseas assets or domicile complexity: different legal systems can collide.
Risk of dispute: estrangement, unequal gifts, or a history of conflict.
Capacity concerns: age, illness, or a diagnosis that could be questioned later.
In these cases, you are not just paying for drafting. You are paying for risk reduction: clearer wording, proper notes, and a structure that stands up when you are not here to explain it.
When you may not need a solicitor
You may be able to manage without a solicitor if:
your estate is simple (one property, straightforward savings)
you are making a single, low-risk change (for example, swapping an executor)
there is no inheritance tax exposure and no trust planning
Even then, you still need correct execution and safe storage. Many people choose a professional anyway because the cost of fixing errors after death can far exceed the cost of getting it right now.
It is also worth clearing up a common misconception: will writing is not a reserved legal activity in England and Wales, so a will writer does not have to be a solicitor. What matters is competence, process, and the ability to spot issues before they become disputes.

Costs, Timescales, And How To Keep Fees Predictable
Cost uncertainty is one of the biggest reasons people put will updates off, and that delay can be expensive in a different way. If something happens before you sign a valid update, your family may have to live with an outdated will or the intestacy rules.
Typical costs: what drives the price
Fees vary by region and complexity, but the biggest cost drivers are usually:
Complex drafting (trusts, life interests, blended family planning)
Tax planning requirements and the need to coordinate with other documents
Asset complexity (business interests, overseas property)
Risk management steps (capacity evidence, detailed attendance notes)
A codicil is often cheaper than a full new will, but it is not always the best value if you are making multiple changes. Paying a little more for a clean, consistent new will can be the cheaper option over time.
Timescales: what you can realistically expect
If your instructions are clear and your estate is straightforward, a will update can often be completed in days to a couple of weeks, depending on appointment availability and how quickly you review drafts.
Delays usually come from:
missing information (full names, addresses, asset details)
difficulty arranging two witnesses at the same time
complex decisions (for example, what "fair" means between children)
How to keep fees predictable
You can usually keep costs under control with three practical steps:
Define the scope upfront: write down exactly what you want to change and what you want to keep the same.
Prepare your information: bring your current will, a simple asset list, and your executor/beneficiary details.
Ask for a clear quote or fixed-fee structure: many providers can quote reliably when the work is well defined.
If you also need related services (for example, probate planning for your executors, or trust documentation), it can help to discuss the full picture so you do not pay twice for overlapping work. Our FAQs can also help you sense-check what is involved before you commit time to appointments.
In short: you can usually make the process predictable by making your instructions specific and your paperwork organised. The law is strict about formalities, but the planning does not have to be stressful.
Where To Store Your Updated Will And How To Make It Easy To Find
A perfectly drafted will can still fail in practice if nobody can find the latest signed version. We see this more often than you might expect: families locate an old will in a drawer, but the newer one is in a safe that nobody can access, or stored digitally without a clear trail.
Good storage options (and what to avoid)
You have a few common choices:
With a professional provider: many will writers or solicitors store the original and provide certified copies. This can reduce the risk of loss or accidental damage.
At home in a secure place: a fire-resistant safe can work, but only if your executors can access it when needed.
Bank storage: some banks offer safe custody, but access after death can be slow and procedural.
Avoid:
leaving the only original in a folder that can be thrown away during a house clear-out
storing it with unclear labelling (for example, "important papers" without dates)
relying on a scanned copy as your only version (useful for reference, but the original signed document matters)
Make it easy for executors
Give your executors three concrete details:
Where the original is stored (full address or provider name)
How to access it (keys, codes, or who to contact)
Which version is the latest (date of will and any codicils)
A practical tip: keep a one-page "estate admin note" separate from your will that lists contact details for executors, where the will is held, and where key documents sit (pensions, life insurance, property deeds). You can update that note without re-executing your will.
If you are already organising your paperwork, it can help to align this with wider planning for later life decision-making too. For example, if you are appointing attorneys, you will also want those documents stored safely and findably.
Storage is not glamorous, but it is one of the most kindness-to-your-family steps you can take.
What Happens After Death: Getting Copies, Probate, And Changing A Will After Death (Deed Of Variation)
After someone dies, families often discover gaps: the will is outdated, an executor cannot act, or a gift no longer makes sense because circumstances changed. At that point, it is too late to "amend the will" in the usual way, and understanding what can (and cannot) happen avoids false hope and wasted time.
Getting copies and confirming the latest will
If you are an executor, you typically need the original will to start probate steps. If the will was stored with a professional firm, you can request it from them. If you only have a copy, you may still be able to proceed, but it can add delay and extra evidence requirements.
A practical step for executors: check for codicils and confirm dates, because the latest valid document controls the estate.
Probate in brief: why the will needs to be clear
Probate is the process that allows executors to collect assets, pay debts, and distribute the estate. Banks and asset holders will often ask for a grant of probate before they release funds.
If the will wording is unclear (for example, contradictory codicils or uncertain gifts), executors may need legal advice, and beneficiaries may face long delays.
Where families need support with the process itself, professional probate services can reduce admin burden and help executors avoid mistakes, especially where there are multiple assets or difficult relationships.
Can a will be changed after death?
Executors cannot rewrite the will because they think it is "unfair", and beneficiaries cannot change it just because they disagree. But, there is one common legal tool that can adjust outcomes in certain cases: a deed of variation.
A deed of variation allows beneficiaries to redirect some or all of their inheritance, often for family reasons or tax planning, as long as:
it is made within two years of death
the affected beneficiaries consent (you cannot vary someone else's entitlement without their agreement)
it is properly documented and executed
A simple example: two adult children inherit equally, but one is financially secure and wants their share to pass to their own children instead. A deed of variation can achieve that cleanly, without forcing a chain of gifts.
If you are reading this before you update your will, the takeaway is clear: do the work while you can. Post-death options are limited, and they depend on other people's agreement.
When you update your will, the goal is not just to "make a change" but to leave a document your executors can use without doubt or delay. In 2026, the basics remain strict: you amend a will properly with a codicil or a new will, you sign with two independent witnesses, and you store the latest version so it can be found quickly. If your situation involves trusts, tax planning, blended families, or any realistic risk of challenge, professional help can turn uncertainty into a clear plan. Take one step now: review your current will against your life today, and write down what you want to change before you do anything else.
Frequently Asked Questions About Amending Your Will
When should I consider amending my will?
You should review and possibly amend your will after major life changes, such as marriage, divorce, having children or grandchildren, buying or selling property, significant changes in assets, or changes to your executors or trustees to ensure it reflects your current wishes accurately.
What is the difference between a codicil and making a new will?
A codicil is a separate legal document for small, specific changes to your existing will, while a new will is recommended for multiple or major changes, clearly revoking earlier wills to avoid confusion during probate.
Can I just handwrite changes on my existing will?
No. Handwritten alterations or notes on the signed will are generally invalid and can cause ambiguity or disputes. Legal amendments must be made by properly signing and witnessing a codicil or new will.
Do I need a solicitor to amend my will?
Professional help is advisable if your estate is complex, involves trusts, tax planning, overseas assets, blended families, or risks of dispute. Simple, low-risk changes may be possible without a solicitor, but proper execution and storage remain essential.
How do I properly execute an amendment to my will?
You must sign the codicil or new will voluntarily, have two independent witnesses over 18 present who also sign in your presence, and ensure the document is clear and unambiguous to be legally valid under UK law.
Where should I store my updated will for safekeeping?
Store the original signed will and any amendments securely at home in a fireproof safe, with a solicitor, bank safe custody, or the Probate Service, and inform your executors how to access the latest version to avoid delays or loss.ext to edit it.
