Jewellery

If it is not given to you then don't claim it as yours.

You may approach the Court

If they gifted you in the time of marriage that right will come to you. If they made on your name and your under undivided hind family that right will not come to you.

This seems to be a complete family matter and I would not suggest you looking at it legally. however, to answer your query the legal owner is person whose name appears on receipt/ who has made payment

plz tell me English
