Judgment & order u/sec. 138 of n. i. act

on 22 Feb 22, on the Criminal Complaint filed by me, I am expecting the Judgment & Order to be pronounced by the Magistrate whereby the Accused is likely to be directed to make payment to me double the amount of Cheque issued to me by him, as well as jail term. I am NOT a Lawyer but since I have experience in lega issues, I had filed the Criminal Complaint myself, conducted entire trial myself and also argued my case on my own, without engaging any Lawyer. Now I want to know as to what happens when the Accused is directed by the trial court to pay the amount to me, but he does not pay? What precautions I must take in advance and on the day of judgment and order, to safeguard the recovery of amounts due to me as to be ordered by the trial courtt? Thanks in advance for kind guidance.
