7.1 Suretyship, Guarantors, and Debtor-Creditor Rights

Key Takeaways

  • REG treats sureties and guarantors together as persons who answer for another's debt; distinguish them when primary versus secondary liability, or the statute of frauds suretyship writing and the main-purpose exception, is in issue.
  • A gratuitous surety must promise before or when credit is extended; a compensated surety's premium supports a later promise. A writing does not replace missing consideration.
  • The surety is discharged by creditor fraud, duress, illegality, payment, material modification without consent (fully if gratuitous; to the extent of loss if compensated), and release of collateral to the extent of its value — but not by the debtor's bankruptcy or minority.
  • After paying, the surety has subrogation, reimbursement against the principal, and pro rata contribution from cosureties; before paying, the surety may seek exoneration.
  • Composition binds only assenting creditors; an assignment for the benefit of creditors is a state-law transfer to an assignee. Neither is a Bankruptcy Code case.

7.1 Suretyship, Guarantors, and Debtor-Creditor Rights

REG Blueprint Area II, Group C tests the rights, duties, and liabilities of debtors, creditors, and guarantors. Bankruptcy types and discharge live in 9.1 Bankruptcy Types and Discharge. This section is the state-law relationship: who promised to pay, what defenses that person has, and what a creditor can do without filing a bankruptcy petition.

Surety versus guarantor

A surety promises the creditor that the principal debtor's obligation will be performed. Traditionally a surety is primarily liable — the creditor may proceed against the surety as soon as the debt is due, without first suing the debtor. A guarantor is secondarily liable — the creditor must look to the debtor first. A guarantor of collection is the strictest form: the creditor must exhaust remedies against the principal (and often show the debt is uncollectible) before charging the guarantor.

REG usually treats sureties and guarantors together as persons who answer for the debt of another. Draw the distinction when it changes the answer: (1) whether the creditor had to pursue the debtor first, and (2) whether the statute of frauds suretyship provision applies. A promise to answer for the debt of another generally must be in a writing signed by the party to be charged — the S in MYLEGS, covered with formation in 6.1 Contract Formation. An original promise (the promisor is buying for themselves) is not a suretyship promise. The main-purpose (leading-object) exception takes the promise out of the statute when the promisor's primary object is to secure a personal economic benefit, not merely to accommodate the debtor. "I'll pay Supplier if you keep shipping steel to my subsidiary, because I need that steel in my own plant" can be an original, enforceable oral promise. "I'll cover my nephew's loan if he defaults" is suretyship and needs a writing.

Formation and consideration

The surety's contract is with the creditor. The principal's contract is the underlying debt.

  • Compensated surety. A bonding company or other surety paid a premium. The fee is consideration. A compensated surety can bind itself after the principal debt already exists, because the premium (or the creditor's forbearance bargained for the bond) is new value.
  • Gratuitous surety. No fee. The promise must be made before or at the same time the creditor extends credit. If the loan is already outstanding and an unpaid friend later says "I'll guarantee it," there is no consideration unless the creditor gives something new: additional funds, an extension of time, or a binding forbearance.

A writing that satisfies the statute of frauds does not supply missing consideration. Signature plus contemporaneous credit, or signature plus a premium, is the exam pattern.

Defenses of the surety

The surety may use real defenses that go to the existence of the debt or to the surety's own assent, and suretyship defenses created by the creditor's later conduct. The surety generally may not use the principal's personal defenses.

DefenseAvailable to the surety?
Fraud or misrepresentation by the creditor inducing the suretyYes. The surety's assent was obtained by the creditor.
Fraud by the principal on the surety, creditor unawareGenerally no. The creditor is not at fault; the surety still owes. If the creditor knew of the fraud and stayed silent, the surety can avoid.
Duress on the suretyYes.
Illegality of the underlying obligationYes. There is no lawful debt to guarantee.
Principal paid, tendered payment, or the debt was otherwise satisfiedYes. Nothing remains to collect.
Material modification of the principal contract without the surety's consent (including an extension of time)Yes. A gratuitous surety is fully discharged. A compensated surety is discharged only to the extent of loss (the prejudice caused by the change). An immaterial change does not discharge.
Creditor's release of collateralYes, to the extent of the value of the collateral released. The surety's expected subrogation cushion was impaired.
Creditor's release of the principalGenerally discharges the surety, unless the creditor expressly reserves rights against the surety.
Release of a cosuretyRemaining surety discharged to the extent of the released surety's contribution share.
Principal's bankruptcyNo. The surety exists so the creditor still has someone to collect from.
Principal's minority (or other lack of capacity)No. Same logic. The surety does not inherit the debtor's personal disability.

That last pair is the highest-yield trap on REG. Bankruptcy and infancy are why the creditor insisted on a surety.

Rights of the surety

Four labels, two timelines:

Before the surety pays — exoneration. The surety may obtain a decree compelling the principal to perform (pay the creditor) so the surety is not called. Exoneration is not a suit for money the surety has already laid out.

After the surety pays:

  1. Subrogation. The surety steps into the creditor's shoes and takes the creditor's rights: the claim, any security interest, any priority, any judgment. Subrogation is how a paying surety gets the bank's Article 9 collateral — the next section, 7.2 UCC Article 9.
  2. Reimbursement (indemnification). The surety has a personal claim against the principal for the amount properly paid.
  3. Contribution. Among cosureties, each is liable for a pro rata share based on their maximum potential liability (unless they agreed otherwise). A surety who pays more than that share recovers the excess from the others. If a cosurety is insolvent, the remaining sureties absorb that share in the same proportions.

Exoneration, subrogation, reimbursement, and contribution are rights against the principal and cosureties, not defenses against the creditor. The creditor who has a solvent surety may collect the full debt from that surety and leave the sureties to sort contribution among themselves.

Worked scenario: two cosureties, one pays the full debt

Facts. Lender is owed $90,000 by Builder. Aunt and BondCo are cosureties on the same debt. Aunt's instrument caps her liability at $90,000; BondCo's bond caps at $90,000. They did not agree to unequal shares. Builder defaults. Aunt pays Lender $90,000. BondCo pays nothing. Builder still holds $20,000 of unencumbered equipment.

Analysis.

  1. Aunt, having paid, is subrogated to Lender's rights, including any security and the claim against Builder, and has reimbursement against Builder for $90,000.
  2. Contribution: equal maximums, so each owes half. Aunt recovers $45,000 from BondCo. BondCo then has reimbursement against Builder for that $45,000. Aunt does not keep both a full $90,000 from Builder and $45,000 from BondCo; contribution and reimbursement are accounted so there is no double recovery.
  3. If BondCo's cap had been $30,000 and Aunt's $90,000, the denominator is $120,000. BondCo's share of the $90,000 paid would be (30/120) times $90,000, or $22,500, not $45,000. Always use maximum liability, not "they both signed."
  4. If Lender had released BondCo without Aunt's consent, Aunt would be discharged to the extent of BondCo's contribution share ($45,000 on the equal-cap facts) and would remain liable for $45,000.
  5. Builder's later bankruptcy would not have been Aunt's defense had she not paid. Discharge of the principal in a federal case is a chapter 9 issue, not a suretyship defense against the creditor.

Creditor remedies (teaching level)

An unsecured creditor has a personal claim and, without a judgment or a consensual lien, no interest in particular property. State-law collection tools:

  • Attachment. A court-ordered seizure of the debtor's property to secure a claim. Prejudgment attachment is extraordinary: the creditor typically must show a risk of concealment or flight and often post a bond. Postjudgment levy and execution are the ordinary way a winning creditor reaches assets.
  • Garnishment. Reaches property of the debtor in a third party's hands — wages, a bank account, an account receivable. Prejudgment garnishment is similarly constrained; postjudgment garnishment is routine after judgment.
  • Execution / levy. Postjudgment seizure and sale of the debtor's nonexempt property.

REG will not ask you to plead a state attachment statute. It will ask whether the creditor already has a judgment, whether the target is in a third party's hands (garnishment) or the debtor's (attachment/execution), and whether a secured creditor is instead using Article 9 repossession (7.2) rather than a judicial writ.

Composition versus assignment for the benefit of creditors

These are state-law alternatives to bankruptcy. Do not import the Bankruptcy Code's chapter structure, trustee avoiding powers, or priority waterfall here.

DeviceWhat happensWho is bound
CompositionDebtor and participating creditors agree that a stated payment (or percentage) satisfies the debts of those who joinOnly assenting creditors. A holdout keeps the full claim.
Assignment for the benefit of creditors (ABC)Debtor transfers assets to an assignee/trustee, who liquidates and pays creditors under state lawThe assignment transfers the debtor's title to the assignee. It is not a federal discharge. Non-assenting creditors may still pursue remaining rights under state law.

A composition is a contract (each participating creditor's agreement to take less is consideration for the others). An ABC is a transfer of property. Neither one is a Chapter 7, 11, or 13 case. If the item names a petition, an automatic stay, or a discharge in a federal court, go to 9.1.
