What it checks.
Each check reads a specific field of TREC’s published 20-19, its position confirmed by rendering the form.
Property address, county — and the address header on every page
Buyer & Seller legal name
Earnest money, option fee, option period days
Escrow agent, title company
Effective Date, and a closing date that’s real and after it
Initials on pages 1–9: one per buyer and seller, from the right person
Sales price math: 3A + 3B = 3C
“Check one box only” conflicts (survey, Seller’s Disclosure, As Is, possession, owners association)
Seller’s Disclosure delivery days and 12B broker contributions filled in
Page 12 receipts match the option fee and earnest money
40-11 addendum loan amount, and Third Party Financing listed and attached
Business terms written into Special Provisions (Paragraph 11)
Notice email addresses that would bounce
Not checked: signatures · TREC forms not listed here · scanned or flattened PDFs
The 40-11 can be its own separate PDF — it doesn’t need to be merged into the contract file.
Checked against the Colorado Real Estate Commission’s published CBS1 (mandatory since January 1, 2026), field by field.
Property street, city, county — and that the state is Colorado
Buyer & Seller names, contract date
§4.1 price table: Earnest Money + loan + Cash at Closing = Purchase Price, and both TOTAL lines
Earnest Money amount and Earnest Money Holder
Loan amount vs. loan type checked (§4.5.3), and Available Funds (§4.4.3)
Blank or N/A deadlines that delete a contingency under §3.2: loan, appraisal, inspection, title objection
§3.1 deadlines out of order (delivery → objection → resolution) or after the Closing Date
Closing Date blank, on a weekend, or on a federal or Colorado holiday
Possession before closing, Acceptance Deadline after closing
Both boxes checked where only one applies, and two payers on one §15 fee
§29 compensation lines checked with no % or $
Lead-based paint deadlines left blank
Amend/Extend and Counterproposal: the contract re-checked as amended — a new date that lands after closing, a deleted loan or inspection deadline, conflicting boxes, a price change
Inspection Objection Notice dated after the Inspection Objection Deadline, or with no description
Attached forms that name a different property or contract date; a Source of Water Addendum listed in §31 but not attached
HB26-1426: the CBS1 marks a buyer’s agent or transaction-broker but no Exclusive Right-to-Buy is attached (signatures aren’t checked); an attached one whose Listing Period doesn’t cover the contract date, names a different buyer, or states no compensation
Not checked: signatures · Foreclosure CBS (CBSF1) and Colorado forms not listed here · scanned or flattened PDFs
