Unlawful Detainer

n. 1) keeping possession of real property without a right, such as after a lease has expired, after being served with a notice to quit (vacate, leave) for non-payment of rent or other breach of lease, or being a "squatter" on the property. Such possession entitles the owner to file a lawsuit for "unlawful detainer," asking for possession by Court Order, unpaid rent and damages. 2) a legal Action to evict a tenant or other occupier of real property in possession, without a legal right, to declare a breach of lease, and/or a judgment for repossession, as well as unpaid rent and other damages. Such lawsuits have priority over most legal cases and therefore will be calendared for trial promptly.
