Under Sections 18 and 19 of the Limitation Act, 1963, a fresh period of limitation is computed where:

Under Section 19 of the Limitation Act, 1963, where payment on account of a debt is made before the expiration of the prescribed period by the person liable to pay the debt, and an acknowledgment of the payment appears in the handwriting of, or in a writing signed by, the person making the payment, a fresh period of limitation is computed from the time when the payment was made. Under Section 18, an oral acknowledgment, an unsigned acknowledgment, or one made after the expiration of the prescribed period does not start a fresh period of limitation.
