4.2 Contract Performance, Breach, and Enforceability

How Contracts End

A contract terminates by performance (the normal path), by mutual agreement, by operation of law, or by breach. The exam tests how each route works and what remedies follow a breach. Expect 4 to 8 questions blending termination, assignment, and remedies.

Performance and Time

Most real estate contracts close when both parties perform. A "time is of the essence" clause makes the stated deadlines strictly binding — a party who is even one day late is in breach. Without that clause, courts allow a reasonable time to perform. Watch for this on the exam: if the clause is present and a buyer misses the closing date, the seller may treat the contract as breached.

Substantial performance is a related idea: when a party performs the essential obligations but leaves minor items undone, the other party must still perform but may deduct the cost to cure the small defects. Distinguish this from a material breach, which goes to the heart of the bargain and excuses the non-breaching party from performing at all. The exam often asks whether a defect is minor (deduct and close) or material (cancel).

Assignment vs. Novation

These two terms are frequently confused, and the exam exploits that.

• Assignment transfers a party's rights (and usually duties) to a third party. The original party generally remains secondarily liable unless released. Most real estate contracts are assignable unless they prohibit it or involve personal services.
• Novation substitutes a new party (or a new contract) and releases the original party from liability. A novation requires the consent of all parties.

Methods of Discharge by Agreement or Law

Beyond performance, a contract can end by:

1. Mutual rescission — both parties agree to unwind and return to their pre-contract positions.
2. Accord and satisfaction — parties agree to accept different performance to settle.
3. Operation of law — bankruptcy, illegality arising later, or the running of the statute of limitations.
4. Impossibility — performance becomes objectively impossible (e.g., the property is destroyed before closing in some states).

Breach and Remedies

When one party fails to perform without legal excuse, the other has remedies. Memorize this remedies table — it is heavily tested.

Worked Numeric: Liquidated Damages

A purchase contract sets the price at $320,000 with a $16,000 earnest-money deposit and a liquidated-damages clause naming the deposit as the seller's sole remedy. The buyer defaults. The seller's actual loss when reselling is later shown to be $25,000.

Under the clause, the seller keeps the $16,000 and cannot sue for the extra $9,000. A valid liquidated-damages clause caps the recovery at the agreed figure. This is why sellers and buyers negotiate the deposit carefully — it can become the ceiling on recovery.

Specific Performance — The Buyer's Power Tool

Because every parcel of land is legally unique, money damages may be inadequate for a buyer. Courts will order specific performance, compelling the seller to convey title. Note the asymmetry: a seller rarely gets specific performance against a buyer (money will make the seller whole), so the seller typically takes liquidated damages or sues for the price difference instead.

A non-breaching party also has a duty to mitigate — to take reasonable steps to limit losses. A seller whose buyer defaults must make a genuine effort to resell rather than let the property sit and then claim a large loss. Damages are reduced by losses that reasonable mitigation could have avoided. Liquidated-damages clauses sidestep this proof problem, which is one reason they are popular: the parties agree in advance what the loss is worth.

Statute of Limitations and Laches

Even a valid claim can die with time. Each state sets a statute of limitations — a deadline to file suit — typically longer for written contracts than oral ones. A separate equitable doctrine, laches, bars relief when a party waits so long that the delay unfairly prejudices the other side, even if the statutory clock has not run. For real estate, written purchase contracts generally enjoy the longer written-contract limitation period, which is why oral side promises are so risky.

Mutual Rescission, Accord and Satisfaction, and Release

Parties can voluntarily unwind or modify obligations:

• Mutual rescission — both agree to cancel and return to their pre-contract positions.
• Accord and satisfaction — the parties agree to accept a different performance (the accord) and then complete it (the satisfaction), discharging the original duty.
• Release — one party gives up a claim, usually for consideration.
• Novation — substituting a new party or contract, extinguishing the old.

Distinguish these from breach (failure to perform) and from impossibility/impracticability (an unforeseen event, such as destruction of the property, that makes performance objectively impossible).

Time Is of the Essence, Waiver, and Substantial Performance

A "time is of the essence" clause makes every stated deadline strictly enforceable — missing a closing date by even one day can be a breach. Without that clause, courts often allow a reasonable extension. A party can also waive a deadline or condition by words or conduct (for example, continuing to proceed after a missed inspection date), and once waived, that protection may be lost.

Not every shortfall is a material breach. Under substantial performance, a party who performs the essential purpose with only minor, non-material defects may still enforce the contract, subject to a credit or offset for the deficiency. A material breach, by contrast, goes to the heart of the bargain and excuses the non-breaching party from further performance while opening the door to remedies such as damages, rescission, or specific performance.
