Which type of lease typically does not require a written agreement if it is for a term of one year or less?

A lease for a term of one year or less is often recognized as a verbal lease under various legal frameworks. Many jurisdictions, including Oregon, allow oral agreements for leases that do not exceed a year in duration. This means that both parties can verbally agree on terms such as rent and duration without needing to put the agreement into writing.

While written leases provide a clearer framework and legal protection for both landlords and tenants, a verbal lease suffices for short-term agreements. Consequently, in real estate practice, it's common for landlords and tenants to engage in verbal leases for shorter durations, as the requirements for documentation are less stringent compared to longer leases, which typically necessitate written contracts to ensure clarity and enforceability.

The other types of leases listed, such as written leases, gross leases, and net leases, can be used in various contexts but often involve more formal structure or longer terms, where written contracts become essential to establish the rights and responsibilities of both parties involved.
