Section 2(b) of the Indian Succession Act defines a codicil as:

‘Codicil’ means an instrument made in relation to a Will, and explaining, altering or adding to its disposition, and shall be deemed to form part of the Will”.

A codicil must be executed similar to Will, being written and attested by two witnesses. Further, as a codicil is a part of the Will, reference must be made to the Will in interpreting the provisions of the Will and vice-versa. Like a Will, a codicil can be altered, added to and further explained by another codicil by proper execution and attestation by witnesses. In most cases, it is easier to create a new Will rather than add a codicil to an existing Will. Creating a new Will by adding clauses like “I revoke all former testamentary dispositions” is more advisable than creating a codicil, which could result in confusion.

In case a codicil is created as an addendum to an existing Will, it should be stored along with the Will with proper attestation. It is recommended that any codicil be reviewed by a professional to avoid any discrepancies or conflicts with the Will.
