What does unlawful detainer imply for a tenant?

Unlawful detainer refers to a situation where a tenant remains in possession of a rental property without the legal right to do so. This typically occurs when the tenant has failed to pay rent or has violated terms of the lease agreement, thereby losing the right to occupy the property. In this context, the term specifically highlights that the tenant is in the property without permission from the landlord, leading to potential legal action to remove them.

The other concepts presented do not accurately define unlawful detainer. For instance, having a legal right to the property contradicts the notion of unlawful detainer. Similarly, while an eviction might occur as a result of unlawful detainer, it does not automatically mean the eviction occurs without notice, as legal procedures typically require notification. Lastly, an expired lease agreement does not inherently mean unlawful detainer exists unless the tenant remains without the landlord's consent. Thus, the focus of the term is clearly centered on the tenant's lack of permission to remain in the property, which is accurately captured in the correct choice.
