In order to recover your money, you can issue legal notice and also proceed by filing a Summary suit under Order 37 CPC(which is the fastest way in indian legal system to recover your money without wasting months/years in courts.
Order 37 CPC is one of the best provisions in the hands of a proposed Plaintiff, wanting to institute a Civil Suit. Broadly it states as under:
Rule 1, Sub-Rule 2 makes it applicable to all suits upon bills of exchange, hundies and promissory notes or the ones in which a Plaintiff seeks only to recover a debt or liquidated demand in money payable on a written contract, an enactment, where the sum to be recovered is a fixed sum of money or in nature of any debt except penalty, a guarantee - in respect of a debt or liquidated demand.
Rule 2 requires an Order 37 Suit to contain among others, a specific averment that the Suit is filed under this Order and no relief which does not fall within the ambit of this Rule is claimed.
The real benefit of an Order 37 Suit is that unless the Defendant is able to demonstrate that he has a substantial defence in his case, the Plaintiff is entitled to a judgment immediately. This in layman’s language means that the stages of filing a WS within 30 days and not later than 90 days, a rejoinder thereafter, admission/denial of documents, framing of issues by Court, leading evidence, cross-examination by parties, final arguments and then finally the judgment/decree, in an ordinary Civil Suit gets eliminated. So all that a Plaintiff has to show is that it is a case which falls within the ambit of Order 37. Once summons is issued, the ball is in the Court of the Defendant to show that he is entitled to a leave to defend, on grant of which the Order 37 Suit becomes an ordinary Civil Suit and the Defendant is then directed to file his WS within 30 days
Hope this helps.
