Sir, I have to take my payment from my customer party & he is not paying

Sir, you must issue a formal Demand Notice to the other party, calling upon them to clear the outstanding dues within a specified period. If the other party still fails to clear the outstanding dues, you must then file an application for mandatory Pre-Institution Mediation and Settlement under Section 12A of the Commercial Courts Act, 2015, before the court or the designated authority. If the mandatory mediation process fails to result in a settlement, you may then proceed to file a formal Recovery Suit before the appropriate Commercial Court under the provisions of the Commercial Courts Act.
