Ways to help us Legacy FAQs How do I include a gift in an existing Will? It is important to review an existing Will regularly to ensure it continues to reflect your circumstances and wishes.

If the only amend you wish to make is the addition of a gift to the BTA, you can use a codicil form which your solicitor will be able to help you complete.
