Addendum or amendment?
An addendum supplements the agreement and can be incorporated later by agreement. An Amendment, Form 39-11, records changes or additions to an executed contract. Ask what the document does, not just when it is signed.

Which TREC form applies?
Learn to spot the fact that changes the form.
New loan or existing mortgage? A changed closing date or a termination notice? Try a short scenario, check your reasoning, and see the official form behind the answer.
Reviewed September 7, 2026 by the Pass Texas editorial team. Original teaching examples, not official exam questions or advice for a live transaction.
How do you choose the right TREC form?
Start with the property and the job the document must do. The base contract covers the sale. Addenda supply additional terms, such as financing or a sale contingency. An amendment records agreed changes to an executed contract. A notice communicates an action under an existing right. A temporary lease addresses occupancy before or after closing.
One transaction may need several documents. This trainer isolates one decision at a time. For an actual transaction, consult your broker and, where legal advice is needed, an attorney.

1. An existing home is being resold
A buyer is purchasing a previously owned duplex. It is not a condominium, a builder's new home, or farm and ranch property. Which base TREC contract fits?
One to Four Family Residential Contract (Resale)
The resale contract covers existing one- to four-family homes, including a duplex. Select the base contract for the property first, then consider financing and other terms that need separate forms.
Common trap: A condominium unit is not covered by this resale form simply because one family will live there.
Check official TREC Form 20-192. A lender will provide a new loan
The buyer plans to obtain a new conventional mortgage from a lender. Which addendum addresses that financing?
Third Party Financing Addendum
The Third Party Financing Addendum addresses financing from a third party for all or part of the purchase price. Here, the buyer is obtaining a new loan, not taking over an existing one.
Common trap: The word mortgage does not mean loan assumption. Ask whether the loan is new or already exists.
Check official TREC Form 40-113. The buyer takes over an existing loan
The parties propose that the buyer assume the seller's existing mortgage instead of obtaining a new loan. Which addendum addresses this arrangement?
Loan Assumption Addendum
Use the Loan Assumption Addendum for the proposed assumption of an existing loan. Check the lender's consent requirements and the addendum's terms. An agreement between buyer and seller does not itself release the seller from liability to the lender.
Common trap: Assuming a loan and releasing the seller from that loan are different issues.
Check official TREC Form 41-34. The seller finances all or part of the price
The seller agrees to finance part of the purchase price and receive payments from the buyer over time. Which addendum addresses the seller-financed portion?
Seller Financing Addendum
The Seller Financing Addendum addresses financing provided by the seller for all or part of the price. A transaction may also include other financing, so identify the arrangement the question asks about.
Common trap: Seller financing does not necessarily mean the seller is the only lender. Actual seller-financing arrangements can require legal and financial advice.
Check official TREC Form 26-85. The purchase depends on selling another property
Buyer and seller agree that the purchase will be contingent on the buyer selling and closing on another property. Which addendum records this contingency?
Addendum for Sale of Other Property by Buyer
The Addendum for Sale of Other Property by Buyer addresses this agreed sale-and-closing contingency. The specified dates and the parties' other rights are governed by its completed terms.
Common trap: Needing money from another sale does not automatically make the purchase contingent on that sale. The parties must agree to the protection.
Check official TREC Form 10-66. A second contract sits behind an existing contract
The seller already has a contract with another buyer. A second buyer and the seller want a back-up contract contingent on termination of the first. Which addendum fits?
Addendum for Back-Up Contract
The Addendum for Back-Up Contract makes the back-up arrangement contingent on termination of the existing contract. Follow the addendum's notice and timing provisions if that happens.
Common trap: A better second offer does not itself cancel the seller's first contract.
Check official TREC Form 11-97. The seller stays briefly after closing
The seller will remain in the home for five days after closing, with the buyer's agreement. Which form addresses that temporary occupancy?
Seller's Temporary Residential Lease
The Seller's Temporary Residential Lease is for seller occupancy of no more than 90 days after closing. It is a lease governing possession, not a financing addendum.
Common trap: Choose by who occupies and when. Buyer occupancy before closing uses the Buyer's Temporary Residential Lease, also limited to no more than 90 days.
Check official TREC Form 15-78. Non-condominium property has mandatory POA membership
An existing single-family home, not a condominium, requires POA membership. Which addendum addresses association information and the resale certificate?
Addendum for Property Subject to Mandatory Membership in a Property Owners Association
The mandatory-membership POA addendum addresses association information and the buyer's elections about obtaining it. It is not for condominiums.
Common trap: Do not substitute this addendum for the condominium contract and its association-related provisions.
Check official TREC Form 36-119. Both parties agree to change an executed contract
Buyer and seller have an executed contract. Both now agree to move the closing date back one week. Which form records their change?
Amendment
An Amendment records agreed changes or additions to an already-executed contract. Both parties sign to agree to the revised closing date. One party's request alone does not change the contract.
Common trap: Do not rely only on timing: an addendum can also be incorporated later by agreement. Here, changing the existing closing date is the job of the Amendment.
Check official TREC Form 39-1110. The buyer exercises an existing termination right
The buyer has a valid, unexpired termination option under the resale contract and has met its option-fee requirements. Which form communicates the buyer's decision to terminate under that right?
Notice of Buyer's Termination of Contract
The Notice of Buyer's Termination of Contract communicates the buyer's election. For this scenario, notice must be delivered within the option period using the contract's notice requirements. The seller does not have to agree to the buyer exercising a valid option.
Common trap: A notice form does not create a termination right, extend an expired deadline, or by itself settle an earnest-money dispute.
Check official TREC Form 38-8Three distinctions worth remembering.
A notice is not a new right.
The buyer must already have a valid basis to terminate and comply with its conditions and notice deadline. Notice Form 38-8 communicates termination; it does not supply a missing contingency.
Form selection is not legal drafting.
TREC Rule 537.11 generally requires the applicable mandatory-use form, with stated exceptions. It allows informational entries but prohibits drafting clauses that define legal rights or giving legal advice. Refer unusual legal issues to an attorney.
Know the name? Now apply the terms.
Recognizing a form is the first step. Next, practice what happens when a deadline, notice, or financing condition changes.
Before you rely on a score or a form.
Does a perfect score mean I am ready for the exam?
No. It means you matched these 10 scenarios correctly. This fixed set does not measure readiness, cover the full Contracts area, or predict a passing score. Retrying uses the same questions, so a higher score can reflect memory.
Are these questions from the licensing exam?
No. Pass Texas wrote these hypothetical examples to teach form recognition. Promulgated contracts, forms, and addenda appear in the Texas sales agent Contracts area of the Pearson VUE content outline. These questions are not official, recalled, or calibrated to the exam's difficulty.
Should I study form numbers or form purposes?
Understand the purpose, conditions, and limits of each form, and study the current version. Form numbers here identify the sources used in this review. We cannot promise what an individual exam question will or will not ask.
Can I use this tool to prepare an actual contract?
No. This is a study aid, not a transaction-specific form selector or legal service. Real transactions may require additional forms, disclosures, lender approval, or attorney-prepared documents. Ask your broker about form selection and consult an attorney for legal advice.
