Sections Contest Property disposition Common types Other types Governing doctrines In the statutory law of wills and trusts, an attestation clause is a clause that is typically appended to a will, often just below the place of the testator's signature.
It is often of the form signed, sealed, published, and declared,[1] a legal quadruplet.
In the United States, attestation clauses were formally introduced into probate law with the promulgation of the first version of the Model Probate Code in the 1940s.
Many states allow attestation clauses to be added as codicils to wills that were originally drafted without them.
[4] Often synonymical with witness, an attestation "testifies to the accuracy or authenticity of something".
