Yes. Many debts based on a simple contract have a usual limitation period of six years from when the cause of action accrued.

In many debt cases, this may be linked to when payment became due. However, the position can depend on the type of debt, the agreement, whether any payment has been made, whether the debt has been acknowledged, and whether the debt arises under a deed or judgment.

Because limitation can be technical, it is sensible to take advice if the debt is old or the deadline may be close.
