Hi sir/madam, no compulsion of marriage eventhough had engagement, it is the wishes of couples. If your father had taken the amount and same it would be deposited in your father bank account, it will be proof of dowry for the girl side. You don't worry. You should express your opinion for not to marry before girl and her parents. They will not compulsion or force the marriage, but they will definitely ask the return of money, if not ask the money or not given the bank account, you should return the money in the name of girl's father Demand Draft along with covering letter by Registered Post and same it could be attached and send through Email to girl or her parents, it is the very helpful to you because of the girl and her parents in case of file the criminal case against yours at that time you have to show it for your side as proof. .... this is one side. another query is that your amount which he had given, that amount was expensed. If yes expensed that amount you should prove that amount was utilised for engagement of yours. But it is very difficut thing. Finally you have to return the money taken some time. It is the best way.
