The 3-Business-Day Right of Rescission, Counted Correctly
The three-business-day right of rescission is one of the shortest deadlines in US consumer finance and one of the easiest to count wrongly, because it uses a definition of "business day" that appears almost nowhere else.
Saturday counts
Start here, because it is the part that catches people. Under the Truth in Lending Act and Regulation Z § 1026.23, the rescission period counts all calendar days except Sundays and the federal legal public holidays listed in 5 U.S.C. § 6103(a). Saturday is a business day for this purpose.
That is a deliberately broader definition than the general one used elsewhere in Regulation Z, and it exists to stop the rescission window stretching across a weekend. The practical consequence is that a period that would run five calendar days on an ordinary Monday-to-Friday count runs only four here.
Close on a Thursday and the three business days are Friday, Saturday and Monday — the right expires at midnight on Monday. Someone counting normal working days would have said Tuesday, and would have advised a client to send a rescission notice a day after the right had gone.
Day zero is the latest of three events
The clock does not start at signing. It starts on the later of:
- consummation of the transaction;
- delivery of the material Truth in Lending disclosures; and
- delivery of two copies of the notice of the right to rescind, to each consumer entitled to rescind.
The counting itself begins the day after that latest event. This ordering matters more than it first appears, because it is what happens when the paperwork is defective. If the notice of the right to rescind was never delivered, or the disclosures were materially wrong, the three-day period never started — and the right can extend for up to three years from consummation, or until the property is sold, whichever comes first.
That extended right is not a technicality. It is the main reason lenders are careful about delivery evidence, and the main reason a borrower with a genuinely defective closing package may have far more time than they assume.
Which transactions carry the right
The right of rescission under 15 U.S.C. § 1635 attaches to consumer credit transactions secured by the borrower's principal dwelling. The significant exclusions are:
- Purchase-money mortgages. A loan used to acquire or construct the home is not rescindable. This surprises people, because it is the transaction most consumers think of first.
- Refinancings with the same creditor, to the extent no new money is advanced beyond the existing balance and costs.
- Loans on a second home or investment property, which are not a principal dwelling.
- Business-purpose credit, which sits outside TILA's consumer scope entirely.
Home-equity loans, HELOCs and cash-out refinances with a new lender generally do carry the right. Calculating the window is the easy part; establishing that the right exists at all is the part worth getting advice on.
What rescinding actually does
A valid rescission voids the security interest and obliges the creditor to return within 20 days everything paid in connection with the transaction — fees, points, closing costs. The borrower in turn tenders back the loan proceeds. It unwinds the transaction rather than merely cancelling a pending one.
Notice must be given in writing and must be sent by midnight of the third business day, not received by then. Sending is the operative act, which is why the method and date of dispatch are worth documenting carefully.
The three-day rule it gets confused with
There is a second three-business-day rule at a mortgage closing and it is a different thing entirely. Under the TRID rules, the lender must deliver the Closing Disclosure at least three business days before consummation. That one uses the general Regulation Z business-day definition in some applications and the broader one in others, and it constrains when you may close rather than how long you may unwind afterwards.
One rule runs before closing and delays it; the other runs after closing and undoes it. Conflating them produces confident, wrong advice in both directions.
Count it deliberately
Three days is short enough that a one-day error is fatal to the right, and the Saturday rule means intuition is actively misleading. Establish the latest of the three triggering events, start counting the following day, include Saturdays, exclude Sundays and federal holidays, and send the notice with a day in hand if you possibly can.
The Right of Rescission calculator applies the Regulation Z definition rather than an ordinary business-day count, so Saturdays are included and the federal holiday calendar is used. It shows the window; whether the right exists on your facts is a question for counsel.
General information about how the rescission deadline is counted, not legal advice. Whether a right of rescission exists, when it was triggered, and how to exercise it all depend on the specific transaction and its documents — confirm with qualified counsel before acting.
