A co-owner of immovable property under the Transfer of Property Act:

Section 44 permits a legally competent co-owner to transfer his own share or interest. The transferee ordinarily acquires the corresponding rights of joint possession or enjoyment and partition, subject to existing liabilities. This does not empower the co-owner to convey the other owners’ shares. The special restriction concerning an outsider’s joint possession of an undivided family dwelling house also remains relevant.
