FIR Quashing Petition Expenses

Good Afternoon, I have to clear my doubt, kindly help...Doubt is...I filed a case against my husband u/s 12 (DV) and a Criminal case (U/s 498a, 406 and 34) The court case went on for 3-4 years, but finally, the settlement was done in MEDIATION and the respondent decided to pay the amount of our marriage. Mediation prepared AGREEMENT PAPERS and we both signed the same, and now there will be 3 motions, in which he has to pay the amount on respective dates and divorce will be done along with this. I have major doubts about the 3rd Motion, it states that...after granting divorce by the court, the petition u/s 482 cr.p.c shall be filed by the respondent for quashing FIR before the High Court and the complainant shall cooperate with the respondent for quashing the FIR. The expenses for filing and drafting of quashing petition shall be borne by the respondent. So, my question is, what is my role in quashing his FIR in the High Court?, How will it be done - will I receive any summons from the High Court? And, Most Importantly, will I have to pay my lawyer separately to appear before the High Court for the quashing proceedings and any documentation work (as the lawyer is already representing my case in the lower court till mediation).
