Who is most likely to utilize the legal remedy known as "Unlawful Detainer"?

The legal remedy known as "Unlawful Detainer" is primarily utilized by the lessor, or landlord, in situations where a tenant has failed to uphold the terms of the lease agreement, such as not paying rent or violating lease conditions. This legal action allows the lessor to regain possession of the rental property by formally evicting the tenant through the court system.

When a landlord initiates an unlawful detainer action, they are seeking a legal pathway to recover their property because the tenant, despite the agreement, has not vacated the premises. It is a crucial process in landlord-tenant law that ensures the lessor's rights to reclaim the property are upheld in a legal manner, rather than through self-help or illegal eviction methods.

In this context, the other roles mentioned—the tenant (often the one being evicted), the lessee (which typically refers to the same party as the tenant), and the property manager (who may act on behalf of the lessor but is not the ultimate party seeking the eviction)—are not the ones initiating this legal remedy. Therefore, the lessor is indeed the party most likely to utilize an unlawful detainer action.
