Plain-English Summary
Instead of an ordinary petition, an eviction case -- whether it stands alone or comes joined with a claim for rent or damages -- starts with an affidavit filed with the court clerk. The Oklahoma Bar Association writes that affidavit form, and the statute specifically requires plain, understandable language rather than legal jargon. The Administrative Office of the Courts then has to make the form publicly accessible, by linking to it on the Oklahoma State Courts Network website.
