The ABC's of Estate Planning: W is for Witnesses
W is for WITNESSES. Most estate planning documents require signatures to be witnessed by two unrelated individuals over the age of eighteen. For some documents, this is to make it valid. In others, it is merely a way to prevent challenges to a document’s authenticity, since a witness indicates to a Notary Public (or in some states an Officer of the Court) that they saw the person sign the document in their presence, and that the signer knew what they were doing.
