INTERESSE TERMINI (Lat. for " interest in a term "), in law, an executory interest, being the right of entry which the grant of a lease confers upon a lessee. Actual entry on the lands by the lessor converts the right into an estate. If the lease, however, has been created by a bargain and sale or by any other conveyance under the Statute of Uses, which does not require an entry, the term vests in the lessee at once. An interesse termini gives a cause of action against any person through whose action entry by the lessee or delivery of possession to him may have been prevented. An interesse termini is a right in rem, alienable at common law, and transmissible to the executors of the lessee.
