If you are a sub-contractor and have not been paid for the work done on a construction project, you can take the following legal steps to recover your dues: Send a legal notice: Send a legal notice to the contractor demanding payment of the outstanding dues. The notice should clearly state the amount due, the work done, and the period for which the payment has been pending. The notice should be sent through registered post with acknowledgment due. File a case in the court: If the contractor fails to respond to the legal notice, you can file a case in the appropriate court. The court can order the contractor to pay the dues along with interest and penalty. Provide proof of work done: Provide proof of the work done and the amount due. This can include contracts, work orders, bills, invoices, and receipts. Engage a lawyer: Engage a lawyer who specializes in construction laws to represent you in the court. The lawyer can guide you through the legal process and represent you in the court. Attend court hearings: Attend all court hearings and provide all necessary information to support your case. Obtain a court order: If the court finds in your favor, it can issue an order directing the contractor to pay the dues within a specified period. Enforce the court order: If the contractor fails to pay the dues even after the court order, you can take legal steps to enforce the order. This can include seizing the contractor's assets, bank accounts, or filing a contempt of court petition. It's important to note that the legal process can be time-consuming and expensive. However, it's important to protect your rights as a sub-contractor and recover the dues that you are rightfully owed.
