A co-signer does not have to be present at closing, but the lender has to approve the alternative in advance. The three workable options are a power of attorney, remote online notarization, or a mail-away closing handled with a mobile notary. Each one takes lead time, often two to three weeks, and some lenders won’t accept certain methods at all, so the conversation with the lender needs to happen early.
Why Remote Signing Works for a Co-Signer
A co-signer’s signing package is narrower than a primary borrower’s. Under Fannie Mae’s guidelines, a co-signer with no ownership interest in the property signs the promissory note but is not named in or required to sign the security instrument.{1Fannie Mae. Signature Requirements for Notes} The note is what creates personal liability for the debt; the deed of trust or mortgage, which ties the loan to the property, is signed by the people who hold title.{2Fannie Mae. Guarantors, Co-Signers, or Non-Occupant Borrowers on the Subject Transaction} Because the co-signer’s documents are fewer and don’t need to be recorded against the property, remote arrangements are easier to coordinate than they would be for a co-borrower on title.
Still, the signature on the note has to be notarized. A notary verifies the co-signer’s identity against a government-issued photo ID and witnesses the signature. That requirement is what shapes every alternative below: whatever method you use, a commissioned notary has to be involved.
Signing Through a Power of Attorney
A power of attorney authorizes someone the co-signer trusts, called the agent or attorney-in-fact, to sign closing documents on the co-signer’s behalf. For mortgage closings, lenders usually want a specific or limited power of attorney that names the exact property, the loan, and the transaction, so the agent’s authority is confined to that single closing.{3Pennymac.

Some programs are more flexible. Pennymac’s guidelines accept a general POA on conventional loans underwritten through Loan Product Advisor, as well as USDA, FHA, and VA loans.{3Pennymac.

A few practical points. The lender has to approve the POA before closing, not at the closing table. Many lenders use their own forms and will reject a document pulled off a template site or drafted independently. Send the proposed POA to the lender at least two to three weeks before the closing date, confirm the named agent is acceptable, and get the approval in writing. Last-minute POA requests are one of the most common reasons closings slip.
Remote Online Notarization
Remote online notarization, or RON, lets a co-signer sign documents electronically while connected to a commissioned notary over a live audio-video session. The notary verifies identity and witnesses the electronic signature in real time, with no one leaving home.{5Mortgage Bankers Association. Remote Online Notarization}
As of 2025, 44 states and the District of Columbia have enacted permanent laws allowing RON for real estate transactions.{5Mortgage Bankers Association.

HR 1059 – 118th Congress (2023-2024) SECURE Notarization Act} So the availability of RON depends on your state. It also depends on your lender and title company; both have to support the specific RON platform used for the closing. Confirm with the lender early whether RON is an option for your transaction.
Mail-Away and Mobile Notary Closings
If RON isn’t available and a power of attorney isn’t practical, a mail-away or split closing is the usual fallback. The closing agent ships the co-signer’s document package by overnight courier. The co-signer meets a local notary, signs the documents in person, has them notarized, and overnights the completed package back to the closing agent.{7Home Closing 101. Closing Options} Build in a day or two on each side of the closing date for shipping.
A variation is hiring a mobile notary or loan signing agent who travels to the co-signer. Fees generally run from about $85 to $400 depending on location and what the service includes, such as printing, scanning, and returning originals. The title company usually has to approve the signing agent in advance. In many cases the co-signer will need to sign a day before the main closing so the originals get back in time for funding.
Some title companies pick the notary themselves and won’t let you choose one, largely as a fraud prevention measure. Check with the closing agent before booking anything on your own.
Plan Early and Confirm in Writing
Whichever option fits, the throughline is lead time. Tell the lender and the closing agent as soon as you know the co-signer can’t attend in person. Ask which methods they accept for this loan program, what form of POA they require if that’s the route, and whether their title partner is set up for RON in the co-signer’s state. Get the approval in writing before the final week.
One point worth keeping in view: signing remotely changes the logistics, not the liability. The promissory note creates the same personal obligation whether it’s signed at the closing table or in front of a notary a thousand miles away. The co-signer’s credit, debt-to-income ratio, and future borrowing capacity are affected the same way either way.{8Chase.
