Amendment History
Laws 1968, SB 537, c. 172, § 1, eff. 1/13/1969; Amended by Laws 1978, HB 1279, c. 257, § 36, eff. 10/1/1978.
Plain-English Summary
This section anchors the forcible entry and detainer act by giving the district court jurisdiction over actions for forcible entry and detention, or detention alone, of real property. It allows one kind of claim to ride along with the eviction claim -- collection of rent, damages to the premises, or a claim under the Oklahoma Residential Landlord and Tenant Act -- but nothing else can be joined in the same action.
The judgment that comes out of this kind of case is conclusive only on the issues adjudicated. It doesn't operate as a bar to either party bringing some other action later -- so, for example, losing on possession doesn't necessarily foreclose a separate suit over other disputes between the parties.
