Demisi

Lat. [from demittere, q. v.] I have demised or leased. Demisi, concessi, et ad firmam tradidi; have demised, granted and to farm let. The usual operative words in ancient leases, as the corresponding English words are in the modern forms.

2 Bl. Com. 317, 318.

From the word demisi in a lease the law implies a covenant upon the part of the lessor that, at the time of the delivery of the lease, he had full power and authority to demise to the lessee for the time and on the terms expressed in the lease.
