Codicil to a Will Template

A codicil lets you amend an existing will — for example changing an executor or a gift — without making a whole new will. It must be signed and witnessed with the same formalities as a will.

When you need a codicil to a will

The legal framework

Understanding the law behind a codicil to a will helps you use it well. Here is the key UK legislation that applies:

Wills Act 1837
Still the governing legislation for wills in England and Wales. Section 9 sets the execution requirements (signed by the testator in the presence of two witnesses who also sign); Section 15 means a witness, or their spouse, who is also a beneficiary forfeits the gift.
Mental Capacity Act 2005
Governs lasting powers of attorney and the capacity required to make a valid will.
Inheritance (Provision for Family and Dependants) Act 1975
Allows certain people to claim from an estate if reasonable financial provision wasn't made for them.
On the horizon. In May 2025 the Law Commission published 'Modernising Wills Law' with a draft Bill proposing significant changes — including enabling electronic wills, ending the rule that marriage revokes a will, and letting courts infer undue influence. These are recommendations only and are not yet law; the Wills Act 1837 continues to apply.

Frequently asked questions

When should I use a codicil instead of a new will?

Codicils suit small, simple changes. For anything substantial, a new will is usually clearer and safer.

Does a codicil need witnesses?

Yes. A codicil must be signed and witnessed with the same formalities as the original will.
