1. You can file a Police FIR, requesting investigation and charge-sheet, for offences like Restraining, Intimidation, Breach of Trust, Mischief etc.... against the Father, supported with all relevant supporting Documents, Evidences & Witnesses.
2. IF the Police does not take action, THEN you can file private criminal case u/s 156(3) Cr.P.C., in the local Magistrates court, seeking directions to the Police to investigate and file charge sheet. Father may come down for settlement.
