Divorce, DV and Dowry charges

Hi. My brother got married in Dec 2022 and in July 2024 he filed the divorce case and one FIR. But in September his wife's family have filed DV and Dowry case which is false. My brother lawyer is suggesting that he shouldn't do anything to claim his innocence. Even we have all the proff to decline all the charges. Instead he is saying to pay the police some money so that they can remove my family members name. Now he is suggesting to make compromise and take back that girl. Thar girl called his BF in my home when my brother was not there and she always harras my parents saying she will file FIR for DV if they ask to do any house chores. She is not working girl nor a student. She spend all her time on phone chatting and VC with her BFs. And send her not appropriate photo to his bfs. Now my brother is thinking that he should do the compromise because between July to Dec he spends so much on lawyer (who is not doing anything) and his mental stress is going on. Can you suggest anything good?
