Yes, some residential lease agreements need to be notarized in Nevada. While most residential lease agreements between the tenant and landlord do not need to be notarized, there is an exception.
If the landlord themselves is not signing the lease, it may need to be notarized. If the signing party is an agent acting on behalf of the landlord, there is precedent for notarization being required in order for the lease to be valid (NV Rev Stat § 118A.200 (4) (2019).
In the case of a standard residential lease between a landlord and a tenant, notarization is not necessary. The lease can be notarized if both parties wish, but it is enforceable as long as it meets the criteria to be legally binding.
