Unity of Time Law and Legal Definition
The unity of time means that the joint tenants held title to the property at the same moment. It is a characteristic because each joint tenant receives his/ her interest at the same time.
In Hill v. Hill, 1983 OK 81 (Okla. 1983), the court held that, a joint tenancy is created only when unities of time, title, interest, and possession are present; unity of time requires interests of joint tenants to vest at the same time.
