N.Y. Personal Property Law § 427: Buyer's or other obligor's right to cancel

§ 427. Buyer's or other obligor's right to cancel. 1. In addition to

any right otherwise to revoke an offer, the buyer or other person

obligated for any part of the purchase price may cancel a door-to-door

sale until midnight of the third business day, or until midnight of the

seventh business day in the case of a door-to-door sale of a personal

emergency response service, after the day on which the buyer has signed

an agreement or offer to purchase relating to such sale.

2. Cancellation occurs when written notice of cancellation is given to

the seller.

3. Notice of cancellation, if given by mail, shall be deemed given

when deposited in a mailbox properly addressed and postage prepaid.

4. Notice of cancellation need not take the form prescribed and shall

be sufficient if it indicates the intention of the buyer not to be

bound.
