If you wish to cancel your will (without preparing a new one), you could simply destroy the original will, with the intention of cancelling it. However, it’s better to make a written declaration revoking your will. This document must be signed in a similar way to how you signed your will — by you with two witnesses looking on and signing it themselves.
You can also cancel your will by preparing a new one. To make it clear you’re cancelling your old will, include a revocation clause at the beginning of a will:
“I hereby revoke all my prior wills and codicils.”
There are several ways you can cancel an electronic will.
You can delete an electronic version of the will, with the intention of revoking it. (Accidentally deleting a version of an e-will shouldn’t indicate an intention to revoke it.)
In the presence of a witness, you can burn, tear or destroy all or part of a paper copy of the will, with the intention of revoking all or part of it.
Ideally though, you should make some kind of written declaration revoking your will. This declaration may be in electronic form and signed with an electronic signature.
Lastly, it is open to you to make a new will, which will cancel your old will. To make it clear you’re cancelling your old will, include a revocation clause at the beginning of the will:
“I hereby revoke all my prior wills and codicils.”
