29 To Whom an Offer Is Addressed See also Formation
2. An offer may create a power of acceptance in a specified person or in one or more of a specified group or class of persons, acting separately or together, or in anyone or everyone who makes a specified promise or renders a specified performance.
CHAPTER 13 - JOINT AND SEVERAL PROMISORS AND PROMISEES
Topic 1 - Joint and Several Promisors
288 Promises of the Same Performance
1. Where two or more parties to a contract make a promise or promises to the same promisee, the manifested intention of the parties determines whether they promise that the same performance or separate performances shall be given.
2. Unless a contrary intention is manifested, a promise by two or more promisors is a promise that the same performance shall be given.
289 Joint, Several, and Joint and Several Promisors of the Same Performance
1. Where two or more parties to a contract promise the same performance to the same promisee, each is bound for the whole performance thereof, whether his duty is joint, several, or joint and several.
2. Where two or more parties to a contract promise the same performance to the same promisee, they incur only a joint duty unless an intention is manifested to create several duties or joint and several duties.
3. By statute in most states some or all promises which would otherwise create only joint duties create joint and several duties.
290 Compulsory Joinder of Joint Promisors
1. By statute in most states where the distinction between joint duties and joint and several duties retains significance, an action can be maintained against one or more promisors who incur only a joint duty, even though other promisors subject to the same duty are not served with process.
2. In the absence of statute, an action can be maintained against promisors who incur only a joint duty without joinder of those beyond the jurisdiction of the court, the representatives of deceased promisors, or those against whom the duty is not enforceable at the time of suit.
291 Judgment in an Action Against Co-Promisors
In an action against promisors of the same performance, whether their duties are joint, several, or joint and several, judgment can properly be entered for or against one even though no judgment or a different judgment is entered with respect to another, except that judgment for one and against another is improper where there has been a determination on the merits and the liability of one cannot exist without the liability of the other.
292 Effect of Judgment for or Against Co-Promisors
1. A judgment against one or more promisors does not discharge other promisors of the same performance unless joinder of the other promisors is required by the rule stated in § 290. By statute in most states judgment against one promisor does not discharge co-promisors even where such joinder is required.
The effect of judgment for one or more promisors of the same performance is determined by the rules of res judicata relating to suretyship or vicarious liability.
293 Effect of Performance or Satisfaction on Co-Promisors
Full or partial performance or other satisfaction of the contractual duty of a promisor discharges the duty to the obligee of each other promisor of the same performance to the extent of the amount or value applied to the discharge of the duty of the promisor who renders it.
294 Effect of Discharge on Co-Promisors
1. Except as stated in § 295, where the obligee of promises of the same performance discharges one promisor by release, rescission or accord and satisfaction,
- co-promisors who are bound only by a joint duty are discharged unless the discharged promisor is a surety for the co-promisor;
- co-promisors who are bound by joint and several duties or by several duties are not discharged except to the extent required by the law of suretyship.
2. By statute in many states a discharge of one promisor does not discharge other promisors of the same performance except to the extent required by the law of suretyship.
3. Any consideration received by the obligee for discharge of one promisor discharges the duty of each other promisor of the same performance to the extent of the amount or value received. An agreement to the contrary is not effective unless it is made with a surety and expressly preserves the duty of his principal.
295 Effect of Contract Not to Sue; Reservation of Rights
1. Where the obligee of promises of the same performance contracts not to sue one promisor, the other promisors are not discharged except to the extent required by the law of suretyship.
2. Words which purport to release or discharge a promisor and also to reserve rights against other promisors of the same performance have the effect of a contract not to sue rather than a release or discharge.
3. Any consideration received by the obligee for a contract not to sue one promisor discharges the duty of each other promisor of the same performance to the extent of the amount or value received. An agreement to the contrary is not effective unless it is made with a surety and expressly preserves the duty of his principal.
296 Survivorship of Joint Duties
On the death of one of two or more promisors of the same performance in a contract, the estate of the deceased promisor is bound by the contract, whether the duty was joint, several, or joint and several.
Topic 2 - Joint and Several Promisees
297 Obligees of the Same Promised Peformance
1. Where a party to a contract makes a promise to two or more promisees or for the benefit of two or more beneficiaries, the manifested intention of the parties determines whether he promises the same performance to all, a separate performance to each, or some combination.
2. Except to the extent that a different intention is manifested or that the interests of the obligees in the performance or in the remedies for breach are distinct, the rights of obligees of the same performance are joint.
298 Compulsory Joinder of Joint Obligees
1. In an action based on a joint right created by a promise, the promisor by making appropriate objection can prevent recovery of judgment against him unless there are joined either as plaintiffs or as defendants all the surviving joint obligees.
2. Except in actions on negotiable instruments and except as stated in § 300, any joint obligee unless limited by agreement may sue in the name of all the joint obligees for the enforcement of the promise by a money judgment.
299 Discharge by or Tender to One Joint Obligee
Except where the promise is made in a negotiable instrument and except as stated in § 300, any joint obligee, unless limited by agreement, has power to discharge the promisor by receipt of the promised performance or by release or otherwise, and tender to one joint obligee is equivalent to a tender to all.
300 Effect of Violation of Duty to a Co-Obligee
1. If an obligee attempts or threatens to discharge the promisor in violation of his duty to a co-obligee of the same performance, the co-obligee may obtain an injunction forbidding the discharge.
2. A discharge of the promisor by an obligee in violation of his duty to a co-obligee of the same performance is voidable to the extent necessary to protect the co-obligee's interest in the performance, except to the extent that the promisor has given value or otherwise changed his position in good faith and without knowledge or reason to know of the violation.
301 Survivorship of Joint Rights
On the death of a joint obligee, unless a contrary intention was manifested, the surviving obligees are solely entitled as against the promisor to receive performance, to discharge the promisor, or to sue for the enforcement of the promise by a money judgment. On the death of the last surviving obligee, only his estate is so entitled.
