Statute of limitations on a debt

Hi,

There is no statute of limitations on a debt; even if many years have passed without an attempt at collection, so long as the bill of debt is valid and so long as a shemitah [Sabbatical] year has not passed since the debt came due [which would have automatically nullified it], the debt may be claimed when the creditor produces his legal document in a Jewish court.

(Shulchan Aruch Choshen Mishpat 98:1)

Have a great day,
Mordechai
