A codicil is a supplementary document that makes changes to an existing will. It allows a testator to alter specific provisions, add new beneficiaries, update executors or amend gifts without the need to draft an entirely new will.
Under English law, a codicil must comply with the same formalities as a will. Section 9 of the Wills Act 1837 requires that it is in writing, signed by the testator and witnessed by two independent witnesses who are present at the same time.
UK codicils are best suited for minor or straightforward amendments. For substantial changes, such as altering the majority of the British will or dealing with complex estate planning, it is generally advisable in England and Wales to prepare a new will to avoid confusion or disputes.
Our codicil template ensures your amendments are clear, properly structured and legally compliant.
Full name, address and identification of the testator making the amendment.
Date and identification of the original will being amended by this codicil.
Clear statement of which clauses are being changed, added or revoked.
Full names and identifying details of any new beneficiaries being added.
Revised monetary gifts, specific bequests or changes to the residuary estate.
Appointment of new executors or removal and replacement of existing ones.
Changes to the appointed guardians for minor children if applicable.
A statement confirming that all other provisions of the original will remain unchanged and in full force.
Proper execution block compliant with Section 9 of the Wills Act 1837.
Space for two independent witnesses to sign and provide their details as required by law.
Follow these steps to make valid amendments to your existing will.

Clearly describe each amendment, referencing the specific clause numbers being changed, added or revoked.
Include a confirmation that all other terms of the original will remain in full force and effect.

Keep the codicil with your original will. Consider lodging both with your solicitor or the Probate Registry for safekeeping.

Reviewed for England & Wales law
Under Section 9 of the UK Wills Act 1837, a codicil must be in writing, signed by the testator (or by someone in the testator’s presence and at their direction), and the signature must be made or acknowledged in the presence of two witnesses who each sign the document in England and Wales.
Witnesses in the United Kingdom must be over 18 and must not be beneficiaries under the UK will or codicil, nor the spouse or civil partner of a beneficiary. If a witness is a beneficiary, Section 15 of the British Wills Act 1837 renders their gift void under English law.
The testator must have testamentary capacity at the time of executing the UK codicil. The British test established in Banks v Goodfellow (1870) requires the testator to understand the nature of the act, the extent of their estate, and the claims to which they ought to give effect under English law.
While there is no legal limit on the number of UK codicils, multiple codicils can create confusion and increase the risk of disputes in British probate. If you need to make more than one or two amendments, it is generally better to prepare a new will in England and Wales that revokes the original and all codicils.
