TREC Forms File-Review Checklists 2026 Changes Free Checklist

TREC Forms

The three forms most Texas resale transactions run through, with current TREC-published effective dates -- straight from trec.texas.gov, not a mirror.

TREC 20-19

One to Four Family Residential Contract (Resale)

The main contract for a residential resale -- single-family homes, duplexes, triplexes, and four-plexes. Not for condos, new construction, or commercial.

Effective July 1, 2026
Official TREC source →
TREC 39-11

Amendment to Contract

Changes or adds terms to a contract that's already been executed -- most often a price change or a closing-date extension.

Effective July 1, 2026
Official TREC source →
TREC 40-11

Third Party Financing Addendum

Required whenever any part of the purchase price is financed by a third party (not seller or buyer). Not attached at all on all-cash deals.

Effective January 3, 2025
Official TREC source →
Also referenced on this site: IABS 1-2 (Information About Brokerage Services), TREC 61-0 (Seller's Disclosure re: Groundwater/Surface Water Rights), and TREC 36-10 (HOA Addendum) -- see what changed → for the full rundown of when each applies.

File-Review Checklists

Organized by the point in the transaction where each check actually matters -- built from the exact fields TC Check verifies on a real file, not a generic industry list.

Run the sample to see what TC Check flags →

Before Sending an Offer

  • Property address, city, and county are complete
  • Buyer and Seller legal names are filled in
  • Sales Price: cash portion (3A) + financing (3B) = total (3C)
  • Earnest money and option fee amounts are filled in
  • Escrow Agent name and Title Company are filled in
  • Financing-type checkbox matches whether a 40-11 is attached
  • Closing date reflects what was actually agreed
  • HOA addendum attached if the property has mandatory membership

After Execution

  • Effective Date is filled in -- the single most commonly missed field
  • Buyer initials present on every page that requires them
  • Seller initials present on every page that requires them
  • All required signatures are present
  • Any executed amendments are attached to the file

Amendment Review (39-11)

  • Exactly one item box is checked -- not more, not zero
  • If price changed, the new Sales Price still reconciles (A + B = C)
  • Amendment correctly references the original contract's address
  • Both parties initialed or signed the amendment itself

Closing-File Review

  • Every field from the "Before Sending" list above is still filled
  • 40-11 loan amount matches Section 3B of the main contract
  • Third Party Financing checkbox agrees between Section 3B and Section 22
  • Initials present on every page, including the addendum
  • No conflicting terms between the contract and any amendment

2026 Changes

What's currently required on the TREC 20-19 -- Paragraph 12B compensation language, the mandatory Water Disclosure, the HOA addendum -- and how it's tracked.
