Final answer:
Reversionary interest and remainderman interest are legal terms associated with property ownership and transfers. Reversionary interest refers to the interest that reverts back to the original owner upon the happening of a certain event, while remainderman interest is the interest that takes effect after the termination of another person's ownership interest.
Step-by-step explanation:
Reversionary interest and remainderman interest are both legal terms associated with property ownership and transfers. Reversionary interest refers to the interest or right that a person has in a property that will revert back to them upon the happening of a certain event, such as the end of a lease or the death of a life tenant. On the other hand, remainderman interest is the interest or right that a person has in a property that will take effect after the termination of another person's ownership interest, such as a life estate.
It is important to note that reversionary interests typically arise in situations where there is a possibility of the property returning to the original owner, while remainderman interests arise in relation to a transfer of property to someone else.
