What Should You Check Before Signing A Codicil In The UK?
A codicil should be treated with the same care as a will. The key practical checks are that the codicil clearly identifies the existing will, states exactly what is being changed, and leaves the rest of the will in force. In England and Wales, the safest signing process is to follow the formalities in section 9 of the Wills Act 1837: the testator signs, or acknowledges their signature, in the presence of two witnesses present at the same time, and each witness signs or acknowledges their signature in the testator’s presence.
Why Are Witness Checks So Important?
Witness arrangements are high risk because a codicil can fail if signing formalities are not followed. Also, a witness or the spouse or civil partner of a witness may lose any gift made to them under the will or codicil, so beneficiaries should not act as witnesses. Use two independent adult witnesses who can see the signing and who are not beneficiaries or closely connected to beneficiaries.
When Is A Codicil Not The Best Option?
A codicil is usually best for a limited, clear amendment. If there are several changes, inconsistent clauses, changes to executors, major changes to gifts, marriage, divorce or uncertainty about the original will, a new will is often safer than adding another codicil.
How Should The Signed Codicil Be Stored?
After signing, keep the original codicil with the original will and tell executors where both documents are stored. Do not attach pages with staples or clips if that may later create questions about missing pages or alteration. Keep copies clearly marked as copies.
