Contract Performance, Contingencies, and Assignment

Once a contract forms, the next questions are how it gets carried out and how it can end or change hands. This spoke picks up after the offer, counteroffer, and acceptance spoke and the earnest money and option period spoke, and it is part of the Contracts and Agency area.

Two ideas carry the topic: the conditions a deal depends on, and the ways contractual rights and duties can move. Learn contingencies, time is of the essence, and the assignment-delegation-novation distinction, and the questions fall into place.

How a contract is performed and discharged

A contract is discharged, or ended, most commonly by full performance, when both parties complete their obligations and the contract becomes executed. Contracts can also end by agreement, such as mutual rescission or novation, or by operation of law. A material breach can give the nonbreaching party remedies and may excuse further performance. An assignment or delegation, however, transfers rights or duties; it does not itself discharge the contract or release the original obligor.

Discharge simply means a contract has ended and the obligations are over. The normal way is performance: each side does what they promised, the sale closes, and the contract is fully performed, or executed.

Other ways a contract ends

Other endings exist and the exam names them. Parties can end a contract by agreement, such as mutually rescinding it or entering a novation. A material breach can permit termination or excuse the other party's remaining performance, depending on the contract and law; a minor breach does not automatically erase the agreement. A duty can also be discharged by operation of law, for example when a recognized impossibility doctrine applies.

Impossibility and the Texas casualty-loss rule

Impossibility is worth one caution, because the textbook example is a house burning down and the TREC contract does not treat that as automatic discharge. Paragraph 14 says the seller shall restore the property to its previous condition by the Closing Date. Only if the seller cannot do so for reasons beyond their control does the buyer get a choice, and it is a choice among three options: terminate with the earnest money refunded, extend the time for performance up to 15 days, or accept the property as damaged with an assignment of the insurance proceeds plus a credit for the deductible.

So casualty in Texas is a set of contract rights, not the common-law doctrine ending the deal by itself. If a question describes a fire and offers "the contract is automatically discharged," that answer is reading general contract law onto a form that says otherwise.

Contingencies and conditions

A contingency is a condition tied to a contractual consequence. If it is not satisfied, the form may terminate automatically or give the protected party a time-limited right to terminate, often with an earnest-money refund. Common real estate contingencies involve financing, property approval or appraisal, sale of the buyer's current home, and title. Always read the condition, deadline, required notice or documents, and stated consequence together.

A contingency is an if-then built into the contract. But the “then” is not universal: one form may terminate automatically, another may give a party a right that expires unless exercised correctly, and another may deem the condition satisfied after a deadline. Contingencies protect only on the terms actually written.

The common ones show up on almost every deal.

In Texas, these are handled through named addenda and specific contract paragraphs rather than free-text clauses, covered in the addenda and statute of frauds guide. The option period from the earnest money and option period spoke also functions as the buyer's inspection window.

Failing a contingency does not always work the same way

"If the condition fails, the buyer terminates and gets the earnest money back" is the right instinct and the wrong level of detail. The Texas forms handle failure in two different ways, and the difference is whether anyone has to do anything.

Automatic termination

Some contingencies terminate the contract by themselves. The Addendum for Sale of Other Property by Buyer, TREC No. 10-6, is the clearest example. Paragraph A says that if the contingency is not satisfied or waived by the stated date, the contract "will terminate automatically and the earnest money will be refunded to Buyer." No notice, no election, nothing to file.

When the buyer must act

Others require the buyer to act, and expire if the buyer does not. The Third Party Financing Addendum is the one to know. Under Paragraph 2A the buyer who cannot obtain Buyer Approval may terminate within a stated number of days after the effective date, but only by giving the seller both a notice of termination and a copy of the lender's written statement of the reasons. Miss it and the addendum says the contract "shall no longer be subject to the Buyer obtaining Buyer Approval." Paragraph 2B works the same way for Property Approval, on a different clock: the buyer must act on or before the third day before the Closing Date, and if they do not, Property Approval "is deemed to have been obtained."

So the trap is not knowing what a contingency is. It is assuming every contingency protects a buyer who sits still. If the buyer misses the Third Party Financing Addendum's Buyer Approval deadline and requirements, the contract is no longer subject to Buyer Approval. That does not erase any other contractual termination right, condition, or defense that may exist; it means this particular protection was lost.

Other form-specific termination rights

Two more termination rights work like contingencies without being called that. Under Paragraph 6D, if the seller does not cure timely title objections within the 15-day Cure Period, the buyer has 5 days after the end of that period to terminate or waive, and failing to act is a waiver. Under Paragraph 7E, if lender-required repairs exceed 5% of the sales price, the buyer may terminate and the earnest money is refunded.

Time is of the essence

Time is of the essence means deadlines are strict and must be met exactly, so performing late is not performing. Where the clause applies, missing a date can put a party in breach rather than merely late. The point most study guides get wrong is scope: in the TREC forms this is not a blanket clause covering the whole contract. It is switched on paragraph by paragraph.

Where the clause actually appears in TREC 20-19

Read the form and the clause appears in specific places, each time scoped to the paragraph it sits in.

Why the closing date is strict for a different reason

Notice what is missing from that list: the closing date. Paragraph 9 contains no time-is-of-the-essence language.

That does not make the closing date soft. It makes it strict for a different reason. Paragraph 9A says that if either party fails to close by the Closing Date, the non-defaulting party may exercise the remedies in Paragraph 15. The consequence is written directly into the closing paragraph, so it does not need the clause.

The distinction matters when a question asks which deadlines carry the strictest treatment, or asks you to justify why a missed date is a default. The right answer for the option fee is Paragraph 5E. The right answer for closing is Paragraph 9A. Saying "the TREC contract is time is of the essence" is a generalization the form does not support.

For the exam, hold two ideas together. Time is of the essence turns a missed date into a serious problem rather than a technicality. And in the TREC forms it is applied deliberately, to the paragraphs where the parties most need certainty, rather than across the board.

Assignment transfers rights; delegation transfers duties

An assignment transfers a party's contractual rights to an assignee. A delegation transfers contractual duties to a delegatee. A transaction can do both, which is why exam summaries sometimes call the whole transfer an “assignment,” but the legal functions are distinct. The original contract remains in place, and delegating a duty does not release the original obligor unless the obligee agrees to a release or novation.

The party transferring a right is the assignor, and the recipient is the assignee. For example, a buyer might assign the right to acquire the property. If the buyer also transfers the duty to pay and close, that second act is a delegation, and the recipient of the duty is the delegatee.

Why assigning a right does not release the duty

The catch that the exam tests is release. Assigning a right does not by itself transfer a duty, and delegating a duty does not by itself discharge the original obligor. If the delegatee fails to perform, the other party may still pursue the original obligor unless that party agreed to a release or novation. Rights are often assignable without the obligor's consent, but contract language, statute, a material change in burden or risk, or the personal nature of the performance can limit assignment or delegation.

One thing to notice about the Texas form: TREC No. 20-19 names the buyer in Paragraph 1 but contains no clause expressly authorizing or prohibiting assignment. That silence does not prove either that every assignment is allowed or that seller consent is always required. Assignment depends on the contract and applicable law. Changing the named buyer on the contract or releasing the original buyer is different from merely assigning a right and generally requires the parties' written agreement or a novation. A license holder should not draft custom transfer language or promise that an “assignment” releases anyone; use broker-approved procedures and qualified legal counsel.

Novation: substituting a party

A novation replaces the original contract or party with a new one, and it requires the consent of all parties. Unlike an assignment, a novation fully releases the original party from liability, because the old contract is extinguished and a new one takes its place. In real estate, a buyer may be replaced by a new buyer through novation, releasing the original buyer, with the seller's consent.

Novation goes a step further than assignment. Instead of just handing off the contract, a novation substitutes a new party or a new contract for the old one, and everyone must agree to it. The old obligation is extinguished and replaced.

The defining feature is release. Because the original contract is replaced, the original party is fully released from future liability. If a buyer is swapped out for a new buyer by novation, the original buyer is off the hook going forward, provided the seller consents. That consent requirement is essential: without the agreement of all parties, there is no novation. Note that novation releases future obligations but does not erase liability for a breach that already happened before the novation.

Assignment, delegation, and novation

The key difference is what moves and whether anyone is released. Assignment transfers rights. Delegation transfers duties, but the original obligor generally remains liable unless released. Novation substitutes a new obligation or party, requires the necessary consent, and releases the original party. In exam shorthand: rights = assignment, duties = delegation, release = novation.

Put the two side by side, because the exam tests the contrast directly.

The one-line memory hook: assignment moves rights, delegation moves duties but ordinarily keeps the original obligor on the hook, and novation supplies the release. When a question describes the original party being released through the parties' agreement, it is novation.

How to study performance and transfer for the exam

Study this topic in two halves. For performance, learn that contracts end mainly by performance, agreement, material breach with the applicable remedy, or operation of law, and that contingencies work only according to their text. For transfer, nail the assignment-delegation-novation distinction: assignment transfers rights, delegation transfers duties without automatic release, and novation releases the original party with the required consent. Apply “time is of the essence” only where the controlling contract or addendum says it applies.

Split your studying. On the performance side, learn how contracts end and read each contingency's deadline, procedure, and consequence. On the transfer side, drill assignment, delegation, and novation until the rights-duties-release distinction is automatic.

Keep this spoke tied to its neighbors. The contract law fundamentals spoke covers what makes a contract valid, the breach and remedies spoke covers what happens when a party fails to perform, and the Contracts and Agency hub ties the area together.

Frequently asked questions

What is a contingency in a real estate contract? A contingency is a condition tied to a consequence in the contract. Common examples involve financing, property approval or appraisal, sale of the buyer's current home, and title. Some forms terminate automatically; others require timely notice, supporting documents, or an election. The party receives only the protection and earnest-money treatment the controlling language provides.

What does time is of the essence mean? It means the deadlines are strict and must be met exactly, so late performance is not performance. In the TREC forms the clause is not blanket. It appears at Paragraph 5E of TREC No. 20-19, scoped to that paragraph, at Paragraph 2 of the Third Party Financing Addendum, and at Paragraph E of the Addendum for Sale of Other Property by Buyer. Paragraph 9, closing, does not contain it.

Is the closing date time is of the essence in a TREC contract? Not by that clause. Paragraph 9 has no time-is-of-the-essence language. The closing date is still strict, because Paragraph 9A provides that if either party fails to close by the Closing Date, the non-defaulting party may exercise the remedies in Paragraph 15. The consequence is built into the paragraph instead.

Does a failed contingency always let the buyer walk with the earnest money? No. Under the Addendum for Sale of Other Property by Buyer, Paragraph A, failure terminates the contract automatically and the earnest money is refunded. Under the Third Party Financing Addendum the buyer must act: Paragraph 2A requires a notice of termination plus the lender's written statement within the stated days, and Paragraph 2B sets the Property Approval deadline at the third day before closing. Missing the applicable deadline removes or deems satisfied that approval protection; it does not eliminate a separate right or defense the contract may provide.

Does a fire before closing end a TREC contract? Not by itself. Paragraph 14 requires the seller to restore the property by the Closing Date. Only if the seller cannot do so for reasons beyond their control does the buyer choose among terminating with the earnest money refunded, extending performance up to 15 days, or accepting the property damaged with an assignment of insurance proceeds and a credit for the deductible.

What is the difference among assignment, delegation, and novation? An assignment transfers contractual rights; a delegation transfers contractual duties. They can occur together, but neither automatically releases the original obligor. A novation substitutes a new party or obligation with the required consent and releases the original party. The exam shortcut is rights = assignment, duties = delegation, release = novation.

Does an assignment release the original party from liability? No automatic release occurs. Assignment of a right does not itself transfer a duty. If the assignor also delegates performance, the original obligor generally remains liable unless the obligee agrees to a release or novation. A novation substitutes the obligation or party and requires the necessary agreement.

Practice questions

1. A financing addendum lets a buyer terminate if the buyer cannot obtain a specified loan and timely delivers the required notice and lender statement. The buyer cannot qualify and complies before the deadline. This is an example of a: A. Novation B. Failed contingency that lets the buyer terminate C. Breach of contract by the buyer D. Time-is-of-the-essence violation

Answer: B. A financing contingency is a condition, and these facts state that the protected buyer exercised the termination right exactly as required. Failure alone would not be enough under every form. It is not a novation (A), a buyer breach (C), or a missed deadline (D).

2. A party transfers their rights under a contract to a third party, but the original contract stays in place and the other side does not release the original party. This is: A. A novation B. An assignment C. A contingency D. A rescission

Answer: B. Transferring rights while the original contract remains and the original party is not released is an assignment. A novation replaces the contract and releases the original party (A), a contingency is a condition (C), and rescission cancels the contract (D).

3. What is required for a valid novation? A. Only the assignor's signature B. The consent of all parties, with the original party released C. A failed contingency D. Nothing, it happens automatically

Answer: B. A novation requires the consent of all parties and replaces the old contract with a new one, fully releasing the original party. One party's signature is not enough (A), a contingency is unrelated (C), and novation is never automatic (D).

4. A party misses the closing date on a TREC One to Four Family contract by several days, with no agreed extension. This is best treated as: A. A minor technicality with no effect B. A default, because Paragraph 9A hands the non-defaulting party the Paragraph 15 remedies C. Automatically excused, since Paragraph 9 is not time is of the essence D. A contingency

Answer: B. Paragraph 9A provides that if either party fails to close by the Closing Date, the non-defaulting party may exercise the remedies in Paragraph 15. It is not a technicality (A). Option C states a true fact and draws the wrong conclusion from it: Paragraph 9 really does lack time-is-of-the-essence language, but the consequence is written into Paragraph 9A instead, so nothing is excused. A missed deadline is not a contingency (D).

5. Which of these does a TREC contract or addendum expressly make time is of the essence? A. The closing date in Paragraph 9 B. Delivery of the earnest money and option fee under Paragraph 5 C. The seller's obligation to complete agreed repairs under Paragraph 7F D. Every deadline in the contract

Answer: B. Paragraph 5E states that time is of the essence "for this paragraph," covering delivery of the earnest money, the option fee, and the option period. Paragraph 9 has no such clause (A), and neither does Paragraph 7F (C). The clause is applied paragraph by paragraph rather than across the contract (D). It also appears at Paragraph 2 of the Third Party Financing Addendum and Paragraph E of the Addendum for Sale of Other Property by Buyer.

6. A buyer's financing contingency is in place, the buyer cannot qualify, and the buyer says nothing until after the deadline in Paragraph 2A of the Third Party Financing Addendum. The buyer is: A. Protected, because the contingency failed B. Entitled to terminate at any time before closing C. No longer protected by the Buyer Approval contingency, though other contract rights may still apply D. Automatically released, with the earnest money refunded

Answer: C. Paragraph 2A lets the buyer terminate for Buyer Approval only by giving the seller a notice of termination and a copy of the lender's written statement within the stated days. If the buyer does not, the addendum provides that the contract “shall no longer be subject to the Buyer obtaining Buyer Approval.” That removes this protection; it does not decide whether some separate contractual right or defense applies. Contrast the Addendum for Sale of Other Property by Buyer, where Paragraph A terminates the contract automatically with no notice.

Sources and methodology

This guide teaches exam-level concepts, not legal advice. It was reverified on August 12, 2026, against the TREC forms then in effect. Discharge, conditions, assignment, delegation, and novation are principally common-law doctrines here, and every claim about a Texas form is cited to the paragraph it comes from.

• The ways a contract is discharged, including performance, agreement, material breach with the applicable remedy, and operation of law, and the nature of a contingency as a condition, come from general contract law as applied to real estate.
• The assignment-delegation-novation distinction comes from general contract law: assignment transfers rights, delegation transfers duties without automatically releasing the original obligor, and novation substitutes an obligation or party and releases the original with the required consent.
• Time is of the essence appears in the Texas forms at Paragraph 5E of the One to Four Family Residential Contract (Resale), TREC No. 20-19, at Paragraph 2 of the Third Party Financing Addendum, TREC No. 40-11, and at Paragraph E of the Addendum for Sale of Other Property by Buyer, TREC No. 10-6. Paragraph 9 of the contract contains no such clause. The forms are adopted by reference at 22 TAC Sections 537.28, 537.47 and 537.21.
• The consequence of failing to close by the Closing Date is Paragraph 9A, which routes to the remedies in Paragraph 15.
• The automatic termination of the sale-of-other-property contingency is Paragraph A of TREC No. 10-6. The notice-plus-lender-statement requirement, the deemed-obtained consequence, and the third-day-before-closing deadline are Paragraphs 2A and 2B of TREC No. 40-11.
• The title-objection Cure Period of 15 days and the buyer's 5 days to terminate or waive are Paragraph 6D. The lender-required-repairs termination right at 5% of the sales price is Paragraph 7E.
• The casualty-loss provisions, including the seller's duty to restore and the buyer's three options, are Paragraph 14.
• The current TREC No. 20-19 contains no express assignment clause. This article does not infer from that silence that assignment is always permitted or always requires seller consent, and it distinguishes assignment from changing the named party or obtaining a release.

Verify all contract rules against the current Texas sources and qualified counsel before you rely on them in practice.
