An action to foreclose a mortgage is subject to a six-year statute of limitations. Where the mortgage is payable in installments, a separate cause of action accrues for each unpaid installment, and the limitations period begins to run on the due-date of each installment. However, once a mortgage debt is accelerated, the entire amount is due, and the statute of limitations begins to run on the entire debt. Acceleration of a mortgage debt requires an unequivocal overt act, such as the commencement of a foreclosure action which specifically invokes that relief. However, where the acceleration occurred by virtue of the filing of a complaint, the noteholder's voluntary discontinuance of that action constitutes, as a matter of law, an affirmative act of revocation of the acceleration, absent an express, contemporaneous statement to the contrary by the noteholder.
