Know exactly what you're personally on the hook for — before you guarantee it.

Whether you are guaranteeing everything, or liability is capped by dollar amount, percentage, time, or a specific obligation — and exactly where that line is drawn.

Whether each guarantor can be pursued for 100% of the debt, so the creditor can collect the whole balance from you regardless of the other signers.

Whether the guaranty silently extends to later renewals, modifications, and new debts you never specifically agreed to.

Waivers letting the creditor come straight at you without first pursuing the borrower, the collateral, or other guarantors.

Spousal signatures and community-property reach — including cases where a spouse appears to be required only because of marital status (an ECOA-sensitive area).

All-asset UCC liens, after-acquired property, home equity, deposit accounts, securities, or a life-insurance collateral assignment.

Clauses that let a creditor obtain a judgment without notice or a hearing — validity varies sharply by state, so the document is flagged for review.

Language that revives the guaranty if a borrower payment is later avoided or clawed back in bankruptcy — long after you thought you were done.

The absence of any mechanism to reduce or end your liability over time, plus acceleration, cross-default, governing law, venue, and jury-trial waivers.
