Which of these leases is enforceable in Texas?

The lease that is enforceable in Texas is the verbal 30-day month-to-month lease. In Texas, a lease for a duration of less than one year can be established verbally and is considered valid. A month-to-month lease allows either party to terminate the agreement with proper notice, typically 30 days, which aligns with the oral nature of the lease in this case. The agreement's flexibility and short duration make it suitable for verbal formation.

Other options present issues that invalidate them within Texas law. A verbal two-year lease agreement lacks the necessary written form required for leases longer than one year under the Statute of Frauds. A written lease signed by an unauthorized representative cannot be enforced because it lacks the proper authority to bind the parties involved. An oral property conveyance between two individuals is subject to the same statutory requirements for real estate transactions, requiring written documentation to be enforceable. Hence, the verbal 30-day month-to-month lease stands as the only enforceable option in this scenario.
