Final answer:
The four unities required for joint tenancy are Unity of Time, Unity of Title, Unity of Interest, and Unity of Possession, which must all be present for this co-ownership arrangement to exist.
Step-by-step explanation:
The four utilities required for joint tenancy are commonly known as the "four unities": Unity of Time, Unity of Title, Unity of Interest, and Unity of Possession. These four unities are essential in creating and maintaining a joint tenancy, a form of property co-ownership.
- Unity of Time indicates that the co-owners must acquire their interests at the same time.
- Unity of Title means that the co-owners must acquire their interests through the same deed or document.
- Unity of Interest requires that the co-owners have equal interest shares in the property.
- Unity of Possession ensures that each co-owner has an equal right to possess the whole property.
If any of these unities are broken, the joint tenancy can be converted into a tenancy in common, where owners hold individual, divisible shares of the property.
