Payment on account of debt restarts the limitation period when made, subject to prescribed acknowledgement requirements. Payment on account of a debt or interest on a legacy made by the debtor or an authorised agent before the prescribed limitation period expires restarts the limitation period, computed from the time of payment, provided an acknowledgment of the payment appears in the debtor's handwriting or a writing signed by the payer; receipt of rent or produce by a mortgagee in possession is deemed payment, and 'debt' excludes money payable under a court decree or order.
