There are two ways you can proceed, one of which is through the criminal process. Under Ark. Code Ann. § 18-16-101, it is a violation of Arkansas law for a tenant to fail to pay rent as agreed, and then fail to vacate ten days after receiving written notice to do so. The City Attorney's Office has a packet for landlords, which contains a copy of Arkansas law, as well as a sample copy of an notice to vacate pursuant to Ark. Code Ann. § 18-16-101. Violations of this law are punishable only by a fine of $25 (each day can constitute a separate violation).
The second way to proceed is to file a civil ejectment action. It is recommended you contact a private attorney to discuss this process. It is also recommended you contact a private attorney to discuss any other questions in regard to your rights against your tenant, except the criminal procedure set out specifically herein, in which the City Attorney's Office can be of assistance to you.
