SBA loan basics
Short answer
It depends. If your spouse owns 20% or more of the business, they must personally guarantee the loan. Even if they own less, their personal guaranty might be required if their assets are needed to secure the loan or if you reside in a community property state.
All owners with a 20% or greater equity stake in the business are required to provide a full personal guaranty. In community property states, spouses of business owners are generally required to sign the guaranty, regardless of ownership, to ensure that any jointly owned assets are available as collateral.
If you own 100% of the business and live in California (a community property state), your spouse would likely be required to sign a personal guaranty even without business ownership to pledge community assets. If you live in a non-community property state and your spouse owns 10%, their guaranty might only be needed if there is a collateral shortfall that requires their personal assets.
Insider move
Lenders ensure all necessary guaranties are obtained to protect the loan. They confirm spousal requirements based on state laws and the need for collateral, as missing a required guaranty can jeopardize the SBA's reimbursement if the loan defaults.
