A life interest (or life rent in Scotland) is a form of right, usually under a trust, that lasts only for the lifetime of the person benefiting from that right. A person with a life interest is known as a life tenant. A life interest ends when the life tenant dies. An interest in possession trust is the most common example of a life interest trust. In a typical interest in possession trust, the life tenant receives all the income from the trust for the rest of his or her life.
