People are taught to hang onto important documents. Every person is instructed to hold onto deeds, mortgages, bank records and tax returns in a safe place where no one else can access them lest important information fall into the wrong hands. But wills, which might be the most important document a person can have, should not be held onto after a new one has been executed, and while it may be a good idea to keep it in a safe place, hiding it like the other documents may have unintended consequences.
Written Revocation
There are many ways to revoke an old will and it is always a good idea to do so if you have drafted a new one. The easiest and most common way to revoke a will is to draft a new one and have an explicit clause that revokes any previous wills and codicils that you have executed. Because your new will is dated later than the previous wills, the revocation will be effective.
