Many people create their wills but realize years later they would like to make a change. This may be to accommodate new family members, distribute newly gained assets, or for some other reason. In this case, the will maker can choose to either write a completely new will and revoke any previous version, or the maker can choose to amend portions of the will using what’s known as a codicil. A codicil is basically a document, usually attached to a will that amends a portion of the text. The legal requirements for a codicil are generally very strict and usually require the will maker’s signature as well as signatures from witnesses. Requirements for a codicil vary greatly by state, so be sure to understand your state’s laws before amending your will.
