Section 255D:21 - Default; enforcement; notice; accelerated payment; curing of default(a) An agreement of the parties in a retail installment contract defining default is enforceable only to the extent that the default is material and consists of the buyer's failure to make one or more installments as required by the agreement; or occurrence of an event which substantially impairs the value of the collateral.(b) After a default by a buyer under a consumer credit transaction, the secured creditor may not bring an action against the buyer or proceed against the collateral until he gives the buyer the notice described in this section. The notice so required shall be deemed to be delivered when delivered to the debtor or when mailed to the debtor at the debtor's address last known to the creditor. If a buyer cures a default after receiving notice and again defaults, the creditor shall give another notice before bringing an action or proceeding against the collateral with respect to the subsequent default, but no notice is required in connection with a subsequent default, if within the period commencing on the date of the consumer credit transaction subject to this section and the date of the subsequent default, the debtor has cured a default after notice three or more times.(c) The notice shall be in writing and shall be given to the buyer ten days or more after the default. The notice shall conspicuously state the rights of the buyer upon default in substantially the following form: The heading shall read: "Rights of Defaulting Buyer Under the Massachusetts Retail Installment Sales Act." The body of the notice shall read: "You may cure your default in (describe transaction in a manner enabling buyer to identify it) by paying to (name and address of creditor) (amount due) before (date which is at least twenty-one days after notice is mailed). If you pay this amount within the time allowed, you are no longer in default and may continue on with the transaction as though no default had occurred.
If you do not cure your default by the date stated above, the said creditor may sue you to obtain a judgment for the amount of the debt or, if applicable, may take possession of the collateral.
If the said creditor takes possession of the collateral, if any, you may get it back by paying the full amount of your debt plus any reasonable expenses incurred by the said creditor if you make the required payment within twenty days after he takes possession."
(d) During the twenty-one day period after a delivery of the notice required by this section the holder may not because of that default accelerate the unpaid balance of the obligation, bring action against the buyer, or proceed against the collateral.(e) Unless the secured creditor has first notified the buyer that he has elected to accelerate the unpaid balance of the obligation because of default, brought action against the buyer, or proceeded against the collateral, the buyer may cure a default consisting of a failure to pay money by tendering the amount of all unpaid sums due at the time of tender, without acceleration, plus any unpaid delinquency of deferral charges. Cure shall restore the buyer to his rights under the agreement as though the defaults cured had not occurred subject to the provisions of subsection (b).Mass. Gen. Laws ch. 255D, § 21
