A more thorough explanation:

A life tenant is a person who has a limited interest in an estate or property that lasts only for their lifetime or the lifetime of another person. This means that they have the right to use and enjoy the property during their lifetime, but they cannot sell or transfer the property to someone else in a way that would extend beyond their lifetime.

For example, if John owns a house and grants a life estate to his son, Tom, then Tom has the right to live in the house and use it during his lifetime. However, he cannot sell the house to someone else or leave it to his heirs when he dies. When Tom dies, the property will pass to the remainderman, who is the person designated by John to inherit the property after Tom's death.

It's important to note that a life tenant can sell or rent their interest in the property, but only for the duration of their lifetime. For example, Tom could rent out the house to someone else, but the lease would end when Tom dies and the property passes to the remainderman.

Overall, a life tenant has a limited interest in a property that lasts only for their lifetime or the lifetime of another person. They have the right to use and enjoy the property during their lifetime, but they cannot sell or transfer the property to someone else in a way that would extend beyond their lifetime.
