(b) Attorney of record. Within ten years after the entry of a judgment the attorney of record or the attorney named on the docket for the judgment creditor may execute a satisfaction-piece or a partial satisfaction-piece, but if his authority was revoked before it was executed, the judgment may nevertheless be enforced against a person who had actual notice of the revocation before a payment on the judgment was made or a purchase of property bound by it was effected.

(c) When the judgment is fully satisfied, if the person required to execute and file with the proper clerk pursuant to subdivisions (a) and (d) hereof fails or refuses to do so within twenty days after receiving full satisfaction, then the judgment creditor shall be subject to a penalty of one hundred dollars recoverable by the judgment debtor pursuant to Section 7202 of the civil practice law and rules or article eighteen of either the New York City civil court act, uniform district court act or uniform city court act; provided, however, that such penalty shall not be recoverable when a city with a population greater than one million persons is the judgment creditor, unless such judgment creditor shall fail to execute and file a satisfaction-piece with the proper clerk pursuant to subdivisions (a) and (d) hereof within twenty days after having been served by the judgment debtor with a written demand therefor by certified mail, return receipt requested.

(d) Where a transcript of the docket of a judgment has been docketed in any other county of the state pursuant to subdivision (a) of section 5018, the person required to execute and file with the proper clerk pursuant to subdivision (a) hereof shall, upon receiving full satisfaction, file a certificate of the clerk of the county in which the judgment was entered, in accordance with subdivision (c) of section 5021, with the clerks of all other counties in which such judgment has been docketed.
