One of the most common questions borrowers ask during a mortgage or refinance closing is whether both spouses — or all co-borrowers — must be physically present together to sign. The answer depends on several factors: whether both parties are on the loan, whether both are on the title, the property’s state, and whether the property is in a community property jurisdiction. Remote online notarization has simplified this process considerably, allowing joint signers to complete their signatures from different locations and at different times when the transaction structure permits it.
This guide breaks down when both spouses must sign, how the process works for joint mortgage notarizations online, and what to prepare to avoid delays at closing.
When Does a Non-Borrowing Spouse Need to Sign?
Even if only one spouse is listed as a borrower on the loan, the other spouse may still be required to sign certain mortgage documents depending on state law and the property’s title status. The most common scenarios include:
Community Property States
In community property states — Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin — property acquired during marriage is generally owned equally by both spouses. In these states, a non-borrowing spouse may be required to sign the deed of trust or mortgage, and sometimes the right of rescission notice, even if they are not on the loan. This protects the lender’s lien priority against any community property claim the non-borrowing spouse might assert.
Homestead Protection States
Many states have homestead exemption laws that restrict a property owner’s ability to encumber or sell their primary residence without spousal consent. In these jurisdictions, both spouses must sign the mortgage or deed of trust regardless of who holds title or whose name is on the loan.
Both Spouses on Title
If the property is owned jointly — both names appear on the deed — both owners must sign any mortgage, deed of trust, or refinance documents affecting the property. This applies regardless of whose name appears on the note (the actual loan obligation).
Both Spouses on the Loan
When both parties are co-borrowers on the mortgage, both must sign all loan documents: the promissory note, the deed of trust, the right of rescission (for refinances), and any lender-required addenda.
How Online Notarization Works for Joint Mortgage Signers
Remote online notarization handles joint signings in one of two ways:
Simultaneous Session
Both signers join the same video call with the licensed notary. Each person verifies their identity independently, signs their respective documents electronically in the notary’s presence, and receives a copy of the completed notarized documents. This mirrors the traditional in-person joint closing and is the most common approach for co-borrowers who are available at the same time.
Sequential Sessions
When co-signers cannot coordinate schedules, some platforms allow sequential signing — each party completes their own identity verification and signing session separately. The notary completes the notarial certificate after all required signatures have been applied. This flexibility is particularly valuable when one borrower is traveling, in a different time zone, or has scheduling constraints that make a simultaneous session impractical.
For any mortgage or refinance, confirm with your lender and title company which approach they accept before scheduling. Our notary for loan documents service supports both simultaneous and sequential signing workflows for joint mortgage closings.
What Each Signer Needs to Prepare
Every individual who must sign mortgage documents and appear before a notary will need:
- A valid, unexpired government-issued photo ID (driver’s license, state ID, or passport)
- Access to the signing platform from a device with a working camera and microphone
- A stable internet connection at their signing location
- Willingness to complete knowledge-based authentication (KBA) questions, if required by the platform
For the non-borrowing spouse who is signing title-related documents but not the loan note, the identity verification requirements are the same. Both parties must be individually verified regardless of which documents they are signing.
Can One Spouse Sign on Behalf of the Other?
In limited circumstances, a properly executed power of attorney (POA) can allow one spouse to sign mortgage documents on behalf of the other. This is known as an attorney-in-fact or POA closing. However, lenders are generally conservative about POA closings — most require pre-approval of the specific POA document before the closing date, and some lenders prohibit them entirely or restrict them to specific circumstances such as military deployment or documented medical incapacity.
If you anticipate needing a POA closing — because one spouse will be traveling, deployed, or otherwise unavailable — notify your lender and title company as early as possible. The POA document itself must also be notarized before it can be used at closing, which means this notarization step must occur in advance of the loan closing date. You can learn more about the preparation involved in our guide on notarizing a power of attorney online.
The Right of Rescission: Both Spouses Must Usually Sign
On refinance transactions secured by a primary residence, the Truth in Lending Act (TILA) gives borrowers a three-business-day right of rescission — the right to cancel the transaction after signing. All persons with an ownership interest in the property (not just the borrowers) must receive the right of rescission notice and sign the acknowledgment. This includes non-borrowing spouses who hold title.
Failure to properly execute the right of rescission notice can extend the rescission period and delay funding. Ensure that every required party — including non-borrowing spouses with title interest — is accounted for in the signing package. The Consumer Financial Protection Bureau has detailed guidance on how the right of rescission works and who must receive and sign the notice.
What Happens If One Spouse Is Unavailable on the Closing Date?
Closing date flexibility is one of the most valuable features of remote online notarization for joint signers. With 24/7 on-demand notary availability, individual signers are not bound to a single closing appointment time. A spouse who is traveling for work can complete their portion of the signing from a hotel room. A spouse in another state can sign from their own home office. The platform coordinates the sessions and assembles the completed package for lender review.
That said, always inform your lender and title company about the signing arrangement in advance. Most lenders need to confirm that all required signatures have been collected before they will authorize funding — and they typically have a maximum window between the last signature and the funding date. Coordinate with your closing team to ensure sequential signing, if used, falls within that window.
Community Property Disclosure and Notarization
In community property states, the non-borrowing spouse may be asked to sign not just the deed of trust but also a community property disclosure or a quitclaim deed. These additional instruments ensure the lender’s lien is protected against any future community property claim. All of these documents can be notarized remotely through the same session or as part of the same closing package.
If you are refinancing a property in a community property state and your spouse is not a co-borrower, discuss the required spouse-signature documents with your title company before closing. Our online notary for real estate documents can handle the full range of instruments involved in these transactions.

Tips for a Smooth Joint Mortgage Notarization
- Identify all required signers early — including non-borrowing spouses and title co-owners — and confirm their availability and ID status before the closing date.
- If community property or homestead laws apply, ask your title company for a complete list of which documents each party must sign.
- For sequential signings, build in a buffer — complete all individual sessions at least one business day before the lender’s funding deadline.
- Confirm with your lender that RON is accepted for your specific loan type and state before scheduling.
- Review documents before the session — do not use the notary session as your first opportunity to read the closing documents.
