Injunction or Writ petition to freeze Dad's bank account for sometime

Hi, We are looking to get some advise and quote for the work to freeze bank account of my father from the court (ideally High court as normal courts are not working) on the basis of below 2 reasons - Dad taken gold of my mother, sister and wife's without our consent - Dad has bipolar mental health condition (doctor issued a certificate). With coronavirus, my sister wedding scheduled this month is postponed. We are currently away from my father hometown Kavali, Nellore district. We have given all documents and evidences to the bank manager and they have temporarily frozen the account. He suggested that they need something from the court to freeze account until our sister wedding where we all come to the town. Can it be: - a writ petition - an injunction order or - a civil case (could be withdrawn when things get back to normal) Whichever is possible and cheaper price. I hope you can understand our concerns and risk of financial losses with our sister's wedding ahead.
