It is clear that the court has passed Ex-Parte judgement in your absence after satisfying from the other party that the summon has already served on the correct address. Now you can move an application before the court which had passed this judgment in your absence.
-- As per law the Limitation period for filing an application for setting aside an ex parte decree is 30 days from the date of knowledge of the decree. So, mentioned in that application that just a few days back you came to know regarding the judgment . But you will have to proof the cause of delay in moving the application .
-- After an ex parte order is set aside the suit is restored to file and parties are relegated to the position they occupied before the non-appearance of the defendant, and the court will proceed with the suit de novo and decide on merits.
-- If an application for setting aside is rejected an appeal lies against such order as well under section 96 CPC.
Hence no need worry take help of any local lawyer and moved an application for setting aside/rejecting the ex-parte order sure the case will start once again , where you will have the option to prove your case.
There is a judgment from the Supreme Court Of India in the case namely Bhanu Kumar Jain v. Archana Kumar that there is no statutory bar to avail the remedies of setting aside the ex-parte because the defendant’s right of appeal under a statute cannot be taken away unless it is not contrary to any other statutory provision
Therefore , dont delay and moved the application .
Good Luck and dont forget to positive Rating.
