A codicil is a supplement to a previous will that adds to, modifies, amends, or revokes one or more provisions of the earlier will. Laws regarding codicils vary from state to state and in some states a codicil may not replace an earlier will—but in some states it may.
In Rhode Island, a codicil is recognized as a legal instrument that can be used to make changes to an existing will. It must be executed with the same formalities as a will, which means it needs to be in writing, signed by the testator (the person making the will), and witnessed by at least two individuals who are present at the same time and understand that the document is a codicil to a will. A codicil can add to, subtract from, or otherwise modify the terms of the will it supplements. However, it is important to note that a codicil does not replace the entire will; it only changes the specific provisions mentioned in the codicil. If a testator wishes to make extensive changes, it may be more appropriate to create a new will. It's also worth noting that the use of codicils has become less common with the advent of digital document storage and word processing, as it is often just as easy to create a new will as it is to draft a codicil.
