What is acknowledgment?

Also called: notarial acknowledgment, notarization

Definition

An acknowledgment is the signer's formal declaration, before a notary or other authorized officer, that they signed the document voluntarily; most states require one before a deed can be recorded.

The officer completes a certificate of acknowledgment on the document. A defective or missing acknowledgment can leave a deed valid between the parties but not entitled to recording, or not notice to later buyers, depending on state law.

How it shows up in a title search

Recorders reject most instruments without it. A recorded deed with a defective acknowledgment is a classic cloud on title, usually cured by re-execution or a curative statute.
