Leaving a bequest is simple and easy to do. To make a bequest, you will need to have a Will. If you already have a Will, all you need to do is add a Codicil, which is an additional document used to make a minor change, amendment or alteration to an existing Will. If you don’t have a Will, we highly recommend you go to your solicitor or see the NSW State Trustee, who will be able to prepare one for you.
