A lease having two or more joint lessees who share a common liability with a lessor. Under a joint and several liable lease the lessor may demand the full terms of the lease from one or all of the lessees and not a prorated share of the lease. For example. Brian and Jack sign a joint and several liable lease to lease a building at the rate of $1,000 per month. Brian defaults on the lease, and Jack is responsible to make the $1,000 monthly payment on the lease.
