SBA loan basics
Short answer
It depends. A non-owner spouse may be required to sign a personal guarantee if their personal assets are jointly held with the borrower and are required as collateral for the loan.
While the SBA requires all owners of 20% or more to guarantee the loan, a non-owner spouse may be required to pledge their interest in jointly owned assets that are taken as collateral. This is to ensure the lender has an enforceable lien on all necessary collateral.
A business owner applies for an SBA loan, and the lender requires a lien on their jointly owned primary residence as collateral. Even if the spouse has no ownership in the business, they would need to sign the personal guarantee to make the lien on the home enforceable.
