Not all personal guarantees impose the same level of liability. The two primary structures are unlimited and limited personal guarantees.
Unlimited personal guarantee is the most common and most demanding form. It makes the guarantor personally liable for the entire outstanding loan balance plus all accrued interest, fees, penalties, legal costs, collection expenses, and any other amounts arising from the default. There is no cap. If a $500,000 loan defaults with $75,000 in accrued interest, $25,000 in attorney fees, and $10,000 in collection costs, the guarantor is liable for $610,000 personally. Unlimited guarantees are the standard for most small business loans, SBA loans, and most alternative financing products.
Limited personal guarantee caps the guarantor's liability at a specified maximum — either a fixed dollar amount or a percentage of the outstanding balance. For example, a limited guarantee might provide that the guarantor is liable for no more than $100,000 on a $500,000 loan, or for no more than 25% of the outstanding balance at the time of default. Limited guarantees are more favorable to borrowers but are far less common — typically available only to businesses with strong collateral coverage, larger deal sizes, or multiple guarantors among whom liability is divided.
Several-but-not-joint guarantees are a variation seen in multi-owner businesses. Rather than joint-and-several liability (where any one guarantor can be pursued for the full amount), several guarantees allocate liability proportionally — each guarantor is liable only for their percentage of ownership. A business with two equal partners might each sign a guarantee limited to 50% of the outstanding balance.
Joint-and-several guarantees are the most lender-favorable: each of multiple guarantors is individually liable for the full outstanding amount, and the lender can pursue whichever guarantor has the most assets, without needing to divide collection efforts among all guarantors. For multi-owner businesses, the partner with the greatest personal net worth bears the practical burden of joint-and-several liability.
