This document only needs to be used if you need to amend your will in any way. A Codicil is a legal document which amends a will by adding a section or changing a current section, whilst leaving the rest intact. The main benefit of using a Codicil is avoiding having to write a new will which can be costly and is unnecessary for smaller amendments. The other benefit to having a Codicil is that it can be used to keep your will up to date and accurate for when you pass away.
How to write a Codicil:

A Codicil can be handwritten or typed but should include the date, state that it is a Codicil and refer to the document and sections it is altering (e.g.the most recent will of John Smith, sections 1, 2 and 3). You can write this document yourself, use online templates or have a solicitor write one on behalf of you.

A Codicil is made legally binding when the signature of the document is witnessed by two valid witnesses.

  • Valid witnesses have the following characteristics:
  • Are over the age of 18
  • Are competent
  • Do not benefit from the will
  • Are not connected to anyone who benefits the will

Once a Codicil is witnessed in the correct way it is essential that it is stored properly to ensure it is carried out. A Codicil must be stored with the will but not attached to it. Storing the Codicil in this way ensures that it can be used in conjunction with your will and that your will (without the amendments) is not just followed alone.

Circumstances where you should consider writing a Codicil:

There are many circumstances in which you may wish to edit your will especially as relationships can shift over the years.

  • Here are some circumstances in which you may need use a Codicil:
  • You have experienced a major change in your life or lifestyle
  • You have had a child
  • You have moved house
  • Your named executor has died
  • You get married
  • You get divorced or separate from your partner
  • You become estranged with someone named in your will
Important considerations:

You should only consider writing a Codicil if you wish to amend or add a small section to your will as when used to amend large portions it can be considered to do more harm than good.

When writing a Codicil, you should ensure that you follow the set-out formalities otherwise the codicil will be invalid and consequently cause doubt regarding your wills own validity.
