If both of you attained the age of marriage then you are free to choose your life partners. No legal consequences ensue for an individual if he marries a person of his own choice. Offensive action at the behest of parents who are obsessed with dogmatic and loathsome social practices which curtail and make subservient to parental choice the right of an individual to choose his/her life partner, is a big menace plaguing the Indian society.
If you apprehend any kind of threat from the parents of girl then move to High Court and seek protection from any kind of harassment which might ensue at the behest of her parents.
