Overview

Delaware guaranties should be reviewed for unlimited liability, future advances, waiver of defenses, collateral pledges, venue clauses, and release mechanics.

Delaware is not a community-property state. ECOA still limits spouse-signature requirements, and Delaware deficiency and exemption issues should be reviewed with the exact borrower, guarantor, and collateral documents.

Enforceability topics to check

Delaware commercial guaranty treatment of confession-of-judgment, cognovit, or warrant-of-attorney wording should be verified by Delaware counsel before relying on the clause.

Frequently asked questions

Can a Delaware guaranty include confession-of-judgment language?

This guide does not make a broad enforceability claim. Any cognovit, confession, or warrant-of-attorney clause should be reviewed by Delaware counsel.

Does Delaware require my spouse to guarantee?

Not simply because you are married. Delaware is not a community-property state, and ECOA limits spouse-guaranty requirements.

What should Delaware borrowers negotiate first?

Start with confession-clause removal, a guaranty cap, future-advance limits, collateral-sale defenses, and written release mechanics.
