Do cheque books expire

In India, cheque books themselves do not have a fixed expiry date as long as the bank account remains active and the cheques comply with current standards. However, individual cheque leaves are valid for only three months from the date of issue. Once this period passes, the cheque becomes "stale" and will be rejected by banks. Additionally, cheque books can become invalid if:

• The bank undergoes a merger, requiring a transition to new IFSC and MICR codes.
• The cheques are non-CTS (Cheque Truncation System) compliant, as these are being phased out for security.
