# Does my spouse have to guarantee my SBA loan?

**Short answer:** SBA requires it if your spouse owns part of the business and both spouses and minor children together hold 20% or more. A spouse who owns nothing signs collateral documents instead. Source: SOP 50 10 8.1, Sec. A, Ch. 5, Para. A.2.

SBA requires it if your spouse owns part of the business and the family's combined stake reaches the threshold. Under SOP 50 10 8.1, Sec. A, Ch. 5, Para. A.2.a, a spouse with a smaller stake must still guarantee in full when both spouses and minor children together hold 20% or more.

## Examples

- You own 15% and your spouse owns 10%. Combined ownership is 25%, so each of you guarantees in full.
- You own 12% and your spouse owns 8%. Combined ownership is 20%, so each of you guarantees in full.
- You own 12% and your spouse owns 5%. Combined ownership is 17%, so this rule does not require either guaranty.

Ownership of married spouses and minor children must be combined when owners are entered in SBA's system (Sec. A, Ch. 1, Para. F). A minor child cannot own 20% or more, because minors cannot legally give a guaranty.

## If your spouse owns nothing

The spousal ownership rule does not make a non-owner spouse a full guarantor. The lender must still require the spouse's signature on the appropriate collateral documents. Any guaranty secured by jointly held collateral is limited to the spouse's interest (Para. A.2.b).

## The lender can still ask

SBA or a delegated lender may require other guaranties for credit or other reasons, regardless of ownership (Para. A.1.c). Spouses who guarantee must also meet the citizenship rules in Sec. A, Ch. 1, Para. F.
