Domestic Violence

Respected Lawyers,My mother has been subjected to domestic violence especially emotional and verbal along with physical for 23 years at the hands of my father and his sisters.She has no Stridhan since the dowry was given in cash form and it was used by my father to build our residential home which is in his name.We are 2 daughters of age above 18.My father is now threatening to marry us off without our consent and if we refused we would be expelled from the house.He says our residential home and all other properties are in his name and bought with his earned money and hence we don't get a thing.And he frequently asks and wishes the three of us to die or commit suicide so that he could get married to a beautiful woman this time.So how should we proceed in this case??We heard at first the couple will be counseled.Is it true??He's a retired serviceman and now works in the intelligent bereau in ARC(Aviation Research Centre) under Defence ministry.His friend once told us that ex-servicemen are given leniency in cases such as these.Is it true?? Thank you in advance for your answers gentlemen...
