It depends on ownership. If your spouse owns 20% or more of the business, they must give a full personal guarantee, just like any other 20%+ owner. If your spouse owns nothing, they generally don't guarantee the loan, but lenders often ask a non-owner spouse to sign a limited guarantee or consent when jointly owned collateral (like your home) secures the loan. Spouses' stakes can also be combined to reach the 20% threshold, so confirm the exact treatment with your lender.
The 20% rule
SBA requires a personal guarantee from everyone owning 20% or more of the borrower. A spouse is not exempt, if they hold 20%+, they sign a full guarantee. See the deeper personal guarantee guide.
| Spouse's ownership | What's typically required |
|---|---|
| 20% or more | Full unlimited personal guarantee |
| Under 20% (but some) | May be required to guarantee depending on lender and aggregation |
| 0% + shared collateral | Often a limited guarantee or consent to a lien on jointly owned property |
| 0% + no shared collateral | Usually no guarantee required |
Why stakes get combined
Under SBA guarantee and affiliation practice, spouses' interests are frequently aggregated. If a husband and wife together own 20%+, both may need to guarantee even if neither individually hits 20%. This is designed to prevent structuring around the threshold.
The guarantee follows ownership, and to the SBA, a married couple's shares often count as one.
The collateral consent for a non-owner spouse
Even a 0%-owner spouse may be asked to sign when the loan is secured by property you own together. That signature is typically a consent to the lien on the shared asset, not a guarantee of the whole loan. It matters because SBA loans can take a lien on available collateral, including a personal residence when needed. Have an attorney explain exactly what your spouse is signing before anyone signs.
This is a legal document with real consequences
A guarantee makes the signer personally liable; a collateral consent can put a shared asset at risk on default. Review every signature page with a qualified attorney, see do you need a lawyer to buy a business.
Frequently asked questions
If your spouse owns 20%+ of the business, yes, a full personal guarantee. If they own nothing, generally no, though lenders often ask a non-owner spouse to sign a limited guarantee or consent when jointly owned collateral secures the loan.
They can. Spouses' interests are often aggregated, so if a couple together holds 20%+, both may need to guarantee even if neither individually reaches 20%. Confirm with your lender.
A guarantee makes you personally liable, and if the loan is secured by a lien on your home, the lender can pursue it on default. A non-owner spouse consenting to a lien is agreeing to that collateral, not guaranteeing the full loan. Review with an attorney.
