A last will and testament is a legal document that must be filed with a probate court after your death. California law normally requires a will must be signed by the maker (testator) and at least two other persons as witnesses. The witnesses need not read or understand the contents of the will, but they must witness the testator’s signature and his declaration that the document is, in fact, intended to serve as a last will and testament.
In most cases, the witnesses play no further role once they have signed the testator’s will. But if a dispute emerges after the testator’s death, a probate judge may require one or all of the witnesses to testify as to the authenticity of the will. Since it may be difficult to locate witnesses what may be years after the fact, California and most states permit what are known as “self-proving” wills. A self-proving will includes an affidavit-that is, a declaration witnessed by a Notary Public-attesting to the authenticity of the document. In other words, the affidavit “proves” the will is authentic without the need to locate and produce the witnesses.
