Personal Guarantee

A personal guarantee is a signed promise by an individual to repay a business's debt if the business does not. The person who signs is the guarantor. If the business defaults, the lender can pursue the guarantor's personal assets, such as savings, investments or a home, as well as the business and its collateral.

Guarantees vary in scope:

• Unlimited. The guarantor is liable for the whole debt, plus interest and collection costs.
• Limited. Liability is capped at a dollar amount or a share of the loan. For example, two partners might each guarantee 50%.
• Payment or collection. A guarantee of payment lets the lender go straight to the guarantor after a default. A guarantee of collection requires the lender to try collecting from the borrower first.
• Carve-out ("bad boy"). Common on commercial real estate loans that are otherwise non-recourse. The guarantor becomes liable only if certain bad acts occur, such as fraud or an unapproved transfer of the property.

Why it matters for lenders

A guarantee gives the lender a second way to be repaid and keeps owners committed when the business struggles. For small and young businesses, the owner's credit and finances are often as important as the company's.

Program rules can require it. As of 2026, the Small Business Administration (SBA) requires anyone who owns 20% or more of a small business applying for an SBA 7(a) loan to give an unlimited personal guarantee, and lenders may ask for more.

A guarantee is only as good as the guarantor's ability to pay. US bank examiners expect lenders to assess and monitor a guarantor's financial capacity, not just collect a signature. Many lenders analyze global cash flow, which combines the business's and the guarantors' income and debts.

There are compliance limits too. In the US, Regulation B under the Equal Credit Opportunity Act bars lenders from requiring a guarantor's spouse to sign, and from asking for guarantees only from married owners. Guarantors are also screened against sanctions lists along with borrowers.

How it works in practice

A community development financial institution (CDFI) approves a $150,000 loan to a restaurant owned by two partners, 60% and 40%. Both sign unlimited guarantees. During underwriting, the analyst collects each partner's personal financial statement, tax returns and credit report, and runs Office of Foreign Assets Control (OFAC) screening on both.

The loan record lists each guarantor, the guarantee type and the documents on file. Each year, the system asks both partners for updated statements and flags the loan if one stops responding.

When guarantor details sit in a shared drive, they go stale. A lender may find, years later, that a guarantor sold their stake or moved assets, and that nobody noticed.
