4.2 Contract Performance, Breach, and Enforceability

Key Takeaways

  • Contracts discharge by performance, mutual rescission, novation, assignment, or operation of law.
  • A material breach lets the injured party choose among remedies: specific performance, damages, rescission, or liquidated damages.
  • Liquidated damages (often the earnest money) cap recovery to a pre-agreed sum and bar suing for more.
  • Specific performance is available because every parcel of real estate is legally unique.
  • Time-is-of-the-essence language makes missed deadlines a material breach.

Contract Performance, Breach, and Enforceability

Most contracts end quietly by full performance. The exam, however, focuses on the contracts that do not — the ones discharged early, transferred to a third party, or broken. Knowing exactly how a contract ends tells you who remains liable and what the injured party can collect.

Ways a contract is discharged

MethodWhat happensLiability point
PerformanceBoth parties fully performContract is now executed; duties end
Mutual rescissionBoth agree to cancel and restore the prior positionEarnest money typically returned
AssignmentOne party transfers rights to a third partyOriginal party usually stays liable
NovationA new party (or new contract) substitutes, releasing the originalOriginal party is released
Operation of lawBankruptcy, statute of limitations, illegalityCourt-driven discharge

The assignment vs novation distinction is heavily tested. In an assignment, the assignor transfers rights but generally remains secondarily liable if the assignee defaults. In a novation, all parties agree to release the original party and substitute a new one — the original obligor walks away clean.

Breach and remedies

A breach is a failure to perform without legal excuse. A material breach (going to the heart of the bargain) lets the non-breaching party choose a remedy:

  1. Specific performance — a court order compelling the breaching party to complete the deal. Available in real estate because each parcel is considered legally unique, so money damages may be inadequate. Buyers commonly seek this against a refusing seller.
  2. Compensatory (actual) damages — money to cover the actual loss caused by the breach.
  3. Rescission — cancel the contract and restore both parties to their pre-contract position.
  4. Liquidated damages — a pre-agreed, reasonable sum (often the earnest money) the parties set in advance as the exclusive recovery.

A partial/minor breach does not justify cancelling the whole contract; the injured party may recover only for the specific shortfall.

Worked numeric: liquidated damages

A buyer signs a purchase agreement for $360,000 and deposits $18,000 in earnest money. The contract states earnest money is liquidated damages if the buyer defaults. The buyer then walks away with no legal excuse, and the seller later resells for $345,000 (a $15,000 lower price).

Because the liquidated-damages clause is the exclusive remedy, the seller keeps the $18,000 earnest money and cannot separately sue for the $15,000 resale loss plus carrying costs. The pre-agreed figure caps recovery. Had the contract contained no liquidated-damages clause, the seller could instead pursue actual damages — but would then have to prove the $15,000 loss and any other documented costs. The trap answer lets the seller both keep the deposit and sue for more; a valid liquidated-damages clause forecloses that.

Time is of the essence

When a contract says "time is of the essence," deadlines become material. Missing a closing date by even one day can constitute a material breach and forfeit the deal. Without that language, courts often allow a reasonable extension and treat minor delays as immaterial. On the exam, watch for the phrase — it converts an ordinary deadline into a make-or-break term.

Defenses that excuse performance

Performance may be excused by impossibility (the subject property is destroyed), mutual mistake, fraud, duress, or a failed contingency. A failed financing or inspection contingency is the most common: the buyer's duty to close never matures because a condition precedent was not met, so walking away is not a breach.

Assignment vs. novation, mechanically

The distinction governs who stays liable:

  • Assignment: rights are transferred to a new party (the assignee), but the original obligor remains secondarily liable if the assignee defaults — unless the contract bars assignment.
  • Novation: a new contract or new party is substituted with the consent of all parties, and the original obligor is fully released.

So a buyer who assigns a purchase contract is still on the hook if the assignee walks; a buyer released by novation is not. The exam embeds the word "released" to point to novation and "assigned" to point to continuing liability.

Statute of limitations and the equitable remedies

A breach claim must be filed within the state's statute of limitations; once it runs, the contract becomes unenforceable even though it was valid. Beyond money damages, courts grant equitable remedies when money is inadequate: specific performance (compelling conveyance, available because each parcel is unique) and rescission with restitution (unwinding the deal and restoring deposits).

Worked numeric: A seller breaches a $500,000 contract; the buyer had a locked-in below-market rate and cannot replicate the deal. Because the parcel is unique and money damages are inadequate, the buyer is well positioned to seek specific performance rather than settle for the return of a deposit. Contrast a seller facing a defaulting buyer, who usually prefers the certainty of keeping liquidated-damages earnest money over a forced-sale suit.

Liquidated damages vs. actual damages, and partial breach

A liquidated-damages clause fixes, in advance, a reasonable, exclusive sum the injured party will recover — most often the buyer's earnest money. Its power is that it forecloses a separate suit for additional actual losses: if the clause is valid, the seller keeps the deposit and cannot also sue for a larger proven loss.

The trade-off is symmetrical — if the loss turns out larger than the deposit, the seller is still capped at the deposit. Without such a clause, the seller may instead pursue actual (compensatory) damages, but must then prove every dollar of loss (the resale shortfall, carrying costs, additional marketing), which is harder and slower.

A material breach goes to the heart of the bargain and lets the injured party cancel and pursue a remedy. A partial (minor) breach does not justify cancelling the whole contract; the injured party recovers only for the specific shortfall and must still perform. Distinguishing the two is a recurring exam task: a one-day delay on a deal without "time is of the essence" is usually minor, while the same delay with that phrase becomes material and can forfeit the deal.

Exam shortcut: "exclusive remedy / pre-agreed sum" points to liquidated damages (no extra suit); "prove the loss" points to actual damages; "goes to the essence" points to a material breach that allows cancellation.
