Colorado · Real Estate Commission formsColorado closing rules: a checklist for transaction coordinators

In Colorado most of the closing rules a TC tracks come from the Real Estate Commission's forms, mandatory from January 1, 2026. The CBS1 residential contract puts every date in one table in §3.1; a day ends at 11:59 p.m. Mountain Time unless a time of day is written, the first day is excluded, and a weekend or holiday deadline moves only if the box says so; a blank or N/A deadline deletes that provision. The seller – not the broker – completes the SPD19 Seller's Property Disclosure and delivers it by the deadline in the contract, and a new adverse material fact after the contract lets the buyer terminate by the earlier of closing or five days after receiving it (CBS1 §§10.1–10.2). A party ends the contract with a written Notice to Terminate the other side receives by the deadline – a late notice is ineffective – and on termination the earnest money is returned to the buyer, subject to the dispute rules (CBS1 §§23–24).

The forms and their deadlines

    Completed by the seller, by the contract deadline.

  3. 3. Notice to Terminate (CBS1 §24)

    Must be received by the deadline; late is ineffective.

Questions about Colorado closings

When does a Colorado contract deadline end?

At 11:59 p.m. Mountain Time on the day, unless a time of day is written (CBS1 §3.3).

Who fills in Colorado's seller's property disclosure?

The seller, to its current actual knowledge – not the broker (SPD19; CBS1 §10.1).

What if a Colorado Notice to Terminate arrives late?

It's ineffective: the party accepts the matter and waives that right (CBS1 §24.1).
