Overview

Massachusetts guaranties often depend on whether liability is unlimited, unconditional, continuing, and supported by personal collateral beyond the business assets.

Massachusetts law has a borrower-friendly statute addressing contract clauses that authorize confession of judgment, and a separate homestead chapter. Both should be reviewed with the exact guaranty and collateral documents.

Enforceability topics to check

Confession of judgment / cognovitHigh confidence

Massachusetts General Laws c. 231, § 13A voids contract provisions where a party agrees to confess judgment or authorizes another person to confess judgment in an action on the instrument.

Mass. Gen. Laws c. 231, § 13A
Deficiency judgments after collateral saleNeeds lawyer verification

Massachusetts deficiency, foreclosure, and UCC-sale issues are fact-sensitive. A guarantor should verify notices, sale process, collateral value, waivers, and any separate guaranty action with Massachusetts counsel.

Borrower protections to negotiate

  • Strike any confession-of-judgment or warrant-of-attorney language and cite Mass. Gen. Laws c. 231, § 13A.
  • Cap guaranty exposure and exclude future advances, amendments, and affiliate obligations without written consent.
  • Preserve sale-notice, valuation, and commercially reasonable disposition defenses for collateral.
  • Keep spouse signatures limited to legitimate collateral or credit-support needs under ECOA.
  • Review homestead, mortgage, and collateral documents together before pledging a residence.

Frequently asked questions

Are confession-of-judgment clauses valid in Massachusetts guaranties?

Massachusetts General Laws c. 231, § 13A voids contract provisions authorizing confession of judgment in an action on the instrument, so this wording should be removed or reviewed immediately.

Does a Massachusetts homestead declaration make a guaranty safe?

No. Homestead protection has limits and exceptions, and it does not neutralize consensual liens, mortgages, or all collateral documents.

What should Massachusetts borrowers negotiate first?

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