comproprietário

comproprietário (co-owner, joint owner)
One of several owners of the same thing: each has their own share, while the thing itself is shared. In renting, this comes up in two situations. First, the tenants of an undivided building that the owner wants to sell are entitled to buy it together, each taking their own share, and they all become co-owners (paragraph 9 of Article 1091.º of the Civil Code). Second, when a flat belongs to several people, all of them sign the tenancy agreement.
Where you come across it. A caderneta predial and land registry certificate showing several owners; an inheritance split between relatives; tenants buying a building together.
A co-owner has their own right of first refusal over another co-owner's share (Article 1409.º), and it takes precedence over other such rights. The shared thing cannot be sold as a whole without the other owners.
