5.3 Interpretation, Conditions & Third Parties

Once a contract exists, disputes turn on what its language means, when duties become due, and who may enforce or be made to perform them. Interpretation rules, the parol evidence rule, conditions, and the doctrines of assignment, delegation, and third-party beneficiaries supply the answers, and each is a recurring topic on the NALA CP Knowledge Exam.

Rules of Contract Interpretation

Courts interpret contracts objectively, seeking the intent the parties manifested in their words and conduct. The plain meaning rule directs that unambiguous language be given its ordinary meaning from within the four corners of the document. When terms conflict, settled canons resolve the tension:

• The contract is read as a whole, so that every clause is given effect if reasonably possible.
• Specific terms control over general terms.
• Handwritten terms control over typed terms, and typed terms control over preprinted terms — the more negotiated the term, the more weight it carries.
• Ambiguities are construed against the drafter (the doctrine of contra proferentem), especially in adhesion contracts prepared by the stronger party.
• Under the UCC, meaning is layered: express terms control over course of performance, which controls over course of dealing, which controls over usage of trade.

Paralegals apply these rules daily when reviewing agreements: defined terms must be used consistently, and any ambiguity flagged in review will usually be resolved against the party whose attorney drafted the document.

The Parol Evidence Rule

The parol evidence rule provides that when the parties adopt a fully integrated writing — one intended as the final and complete expression of their agreement — evidence of prior or contemporaneous oral or written agreements may not be used to contradict or vary its terms. A merger clause (a clause stating that the writing is the entire agreement) creates a presumption of total integration. If the writing is only partially integrated, consistent additional terms may still be proved, and under UCC Section 2-202 consistent additional terms are admissible unless the court finds the writing was intended as complete and exclusive.

The rule carries exam-worthy exceptions. Parol evidence is always admissible to show:

• Fraud, duress, undue influence, mistake, or illegality
• An ambiguity in the writing (evidence may explain, but not contradict)
• A condition precedent to the agreement's effectiveness
• Subsequent modifications made after the writing was signed
• A separate agreement supported by separate consideration
• Course of dealing, course of performance, or usage of trade under the UCC
• Grounds for reformation of a writing that fails to reflect the parties' true agreement

The most common trap: the parol evidence rule never bars evidence of events occurring after the writing was signed. A later oral modification is admissible, although it may independently require a writing under the Statute of Frauds, and no-oral-modification clauses are enforced under the UCC.

Conditions

A condition is an event, not certain to occur, that must occur or be excused before a performance obligation matures. Failure of a condition is not a breach; it simply means the conditioned duty never arises (or is discharged). Courts prefer to construe doubtful language as a promise rather than a condition in order to avoid forfeitures.

Conditions may be express (stated with words like 'provided that,' 'on condition that,' or 'if') or implied (constructive conditions, such as the rule that substantial performance by one party must precede the other's duty to pay). Conditions of personal satisfaction are judged subjectively for matters of taste, such as a portrait, but objectively — by the reasonable person standard — for mechanical fitness or utility. A condition may be excused by waiver, by the protected party's hindrance or bad faith, or by anticipatory repudiation.

Assignment and Delegation

Assignment transfers contractual rights; delegation transfers contractual duties; a transfer of 'the contract' generally does both. An assignee steps into the assignor's shoes and takes the rights subject to the same defenses the obligor had against the assignor. Rights are generally assignable unless the assignment would materially vary the obligor's duty or risk, the right is highly personal, a statute or public policy forbids it (many wage assignments are regulated), or the contract validly prohibits it — modern courts read a bare anti-assignment clause narrowly, often as barring only delegation or as giving rise to damages rather than voiding the transfer. Assignments for consideration are irrevocable; gratuitous assignments are generally revocable, and a later assignment for consideration usually revokes an earlier gratuitous one. An obligor who pays the assignor before receiving notice of the assignment is discharged, so prudent assignees give prompt notice.

Duties are delegable unless they involve personal skill, judgment, or trust (a lawyer's or an artist's services), or the contract forbids delegation. The critical rule: delegation does not discharge the delegator, who remains liable if the delegatee fails to perform. Only a novation — an agreement among the obligor, the delegator, and the delegatee substituting the new party and releasing the old one — extinguishes the original duty.

Third-Party Beneficiaries

Only an intended beneficiary may sue on a contract made for his or her benefit; an incidental beneficiary — one who profits only as an unintended byproduct — acquires no rights. Intended beneficiaries come in two classic forms: a creditor beneficiary, whom the promisee intends to benefit in satisfaction of a debt the promisee owes (a buyer of mortgaged property promises the seller to pay the mortgage; the lender is a creditor beneficiary), and a donee beneficiary, whom the promisee intends to benefit by gift (the named beneficiary of a life insurance policy). The modern Restatement folds both into the single category of intended beneficiary, asking whether recognition of enforcement rights is appropriate to effectuate the parties' intent. The beneficiary's rights vest — and the original parties lose the power to modify or rescind them — when the beneficiary materially relies on the promise, assents to it, or brings suit; until vesting, the contracting parties remain free to change the deal.

Paralegal Practice Notes

Paralegals flag merger clauses and integration questions in document review, track financing and inspection conditions on closing checklists so condition deadlines are met, confirm that anti-assignment clauses are honored before transferring contract rights, and verify whether novation language — not mere delegation — is present when a client seeks to exit a contract.
