Deeds, mortgages, and other important papers often require a notary's signature.
Background
A notary creates a “certificate of acknowledgment” confirming that the signer personally appeared and stated they voluntarily signed the document.
Purpose
For real property matters, many states require proper acknowledgment before a document provides public notice. Documents affecting real property should receive proper acknowledgment and recording.
Conclusion
All recorded documents should receive notarization to maximize their legal standing and enforceability.
