Common Examples

Board Members Attest Printed Will
Dana printed a photograph of whiteboard notes that set out her estate plan and signed the printout at the bottom. She then asked two board members to sign in the margin while she remained present. The two signatures supplied the attestation needed for the document to qualify as a validly executed will under governing procedures.
Self-Proved Will Execution Ceremony
Carlos signed his handwritten will at the kitchen table in front of two neighbors. The neighbors then signed affidavits before a notary acknowledging that they had witnessed Carlos sign or acknowledge the document. Their combined signatures and affidavits allowed the will to be simultaneously attested and made self-proved.

Common questions
Frequently Asked
4
Must attesting witnesses read or understand the will's contents?+
No. The governing rules require only that the witnesses sign after observing the testator sign or acknowledge the will. Their signatures confirm the execution ceremony occurred. They need not review the substantive provisions.
Supporting sources
Can witnesses sign on different days?+
Yes, provided each properly attests under the procedures supplied by applicable law. The core requirement is the presence of the required number of signatures on the written instrument. Same-day signing is not mandated by the Restatement or UPC provisions.
Supporting sources
Does an interested witness invalidate the will?+
No. Modern statutes provide that an interested witness's signature does not invalidate the will or any provision of it. The presence of a second, disinterested witness further supports validity.
Supporting sources
What role do attesting witnesses play when a will is offered for probate?+
Their testimony or affidavit establishes due execution. When the will is self-proved, the acknowledgment and affidavits satisfy the execution requirements without live testimony from any attesting witness.
