A wet signature is a handwritten ink signature on a paper mortgage document, often used when electronic signing is not enough.
A wet signature is a handwritten ink signature placed on a physical paper document. In a mortgage closing, some documents may still require wet signatures even when the rest of the package is signed electronically.
The accepted signing method depends on the document, lender, investor, title insurer, settlement provider, recording office, state law, and notarization rules. A digital portal does not by itself make every mortgage document eligible for electronic execution.
Wet-signature requirements affect logistics. The borrower may need an in-person Signing, original documents may need overnight delivery, and the closing team may be unable to fund until it receives and reviews the signed package.
A wet signature and notarization are separate concepts. The signature describes how the borrower signs; notarization is the notary’s identity, willingness, and acknowledgment or oath process. A wet-signed document may or may not require notarization.
Borrowers learn the closing format after final documents are prepared. A fully paper closing uses wet signatures throughout. A Hybrid Closing allows some documents to be e-signed before or during the appointment while a smaller paper set is signed in ink.
The signer should use the exact legal name shown on each document, follow instructions about initials and dates, and avoid corrections that the settlement agent has not approved. Missing signatures or improper corrections can delay Funding.
| Format | How documents are generally executed |
|---|---|
| Paper closing | Documents are printed and signed in ink; notarized documents use an in-person notary |
| Hybrid Closing | Eligible documents are e-signed; remaining documents receive wet signatures |
| Electronic closing | Eligible documents are signed electronically within an approved system |
| Remote Online Notarization | Notarial acts occur through an approved audio-video and identity-verification process |
Actual packages can combine these methods. Borrowers should ask what equipment, identification, witnesses, and physical delivery will be required before the appointment.
| Term | Main idea | Borrower-facing difference |
|---|---|---|
| Wet signature | Ink signature on paper | The borrower signs a physical document |
| Electronic Signature | Digital signing method | The borrower signs through an approved electronic process |
| Hybrid Closing | Mixed closing format | Some documents are electronic and others remain paper or notarized |
| Remote Online Notarization | Online notarization process | Notarization happens through a digital workflow when allowed |
| Signing | Final document execution step | Signing may involve wet signatures, electronic signatures, or both |
A borrower e-signs 70 pages the evening before closing. At the appointment, the borrower signs the promissory note and security instrument in ink, and the notary handles the required acknowledgments. The original paper set is returned to the settlement team before funding.
Wet signature differs from Electronic Signature because it is handwritten on a physical original rather than applied through an electronic system.
It differs from Remote Online Notarization because remote notarization describes how a notarial act occurs. It does not simply mean emailing a scanned wet-signed page to a notary.
It also differs from Hybrid Closing. Hybrid closing is the overall format, while wet signature is one possible requirement inside that format.
