Your father is the co-owner in the property and registration also done under their name first you have to understand what is the right of Ownership and what it contains, basically ownership imports three essential rights, namely right to possession, right to enjoy and right to dispose of if an owner is wrongly deprived of possession of his property, he has a right to be put in possession thereof. All the three essentials are satisfied in the case of co-owner of a land. All co-owners have equal rights and co-ordinate interest in the property, though their shares may be either fixed or indeterminate. Every co-owner has a right to enjoyment and possession equal to that.[See Abhey Singh v. Gian Singh and Ors. 1971 JKLR 326]

wherein a Single Bench of this Court held that a co-sharer has no right to built on a joint property without the consent of other co-sharer.

[See:Harendra Nath Ghosh & Ors. vs Subodh Kumar Ghosh & Ors. on 17 February, 2000] in this case also Court discussed the rights of Co-owner and said that a co-owner without taking consent of other co-owner cannot make any construction over any portion of the property in excess of his share or with the object to embarrass any other co-owner or to hinder any effective partition or to diminish the value of the joint property, even if such construction is within his share. If a co-owner makes any construction with the above motive, the other co-sharer is entitled to get an order of injunction restraining such a wrong doer from doing such wrongful act.
