Witnesses And Self-Proving Affidavits
A will is proved as much by how it was signed as by what it says, and the witnessing formalities exist to answer questions long after everyone involved is unavailable.

A will has to be proved before a court will act on it, and that proof rests on how the document was executed. The formalities exist because the signer cannot be asked anything later.
Why witnesses are required at all
The signing ceremony creates evidence that the document is the one the testator meant to sign, that they signed it voluntarily, and that they appeared capable of understanding what they were doing.
Witnesses supply the only account of that moment from people other than the person who benefits. Their presence is what allows a court to accept the will when no other proof exists.
Most American states require two witnesses for a typed will, though the details of who qualifies and what they must observe vary and change over time.
Interested witnesses create a problem
A witness who also inherits under the will raises the concern the requirement was designed to address, since that person is not an independent observer of the signing.
States handle this differently. Some void the gift to that witness while leaving the rest of the will intact, others treat it as a factor rather than a disqualification.
Because the outcome depends entirely on the jurisdiction, using witnesses with nothing to gain is the practice that avoids the question altogether.
What a self-proving affidavit does
A self-proving affidavit is a sworn statement, usually signed before a notary at the same time as the will, in which the testator and witnesses confirm the ceremony took place properly.
Its purpose is to spare the estate from having to locate those witnesses years later and bring them to court to testify about a signing they barely remember.
Where the affidavit is recognized, the will can generally be admitted without live testimony, which shortens the opening stage of probate considerably.
What happens without one
A will lacking the affidavit is not invalid, but proving it may require locating a witness, obtaining a sworn statement, or in some cases proving handwriting through other means.
Witnesses move, change names and die. A will signed decades earlier can leave an executor searching for two people whose only connection was being in an office that afternoon.
The delay is rarely fatal to the estate, but it is avoidable, and it arrives at the moment a family least wants an obstacle.
Where the requirements sit
Execution requirements, the treatment of interested witnesses, notarization and whether electronic signing is recognized are set by state law and have been revised in recent years.
A will valid where it was signed is often honored elsewhere, but that is a general tendency rather than a guarantee, and it matters for anyone who has moved.
An estate planning attorney supervising the signing is the ordinary way people ensure the ceremony matches whatever their state currently requires.
