Civil procedure in Oklahoma
Civil cases in Oklahoma state courts follow the Oklahoma Pleading Code (Title 12, Oklahoma Statutes). Federal courts located in Oklahoma follow the Federal Rules of Civil Procedure and their own local rules. Individual Oklahoma courts also publish local rules, and judges may issue standing orders — read all of them before filing.
Our procedure library explains each federal motion and filing; look up the Oklahoma equivalent in the state rules, because names, deadlines and forms can differ.
Foreclosure in Oklahoma
The most common foreclosure process in Oklahoma is judicial: the foreclosing party files a lawsuit and needs a court judgment before a sale. The main statute: 12 O.S. § 686 (judicial); 46 O.S. § 43 (power of sale).
Federal mortgage servicing rules also apply to most residential loans — see federal pre-foreclosure protections. Read the current statute for notice periods, redemption rights and deficiency rules.
The Uniform Commercial Code in Oklahoma
Oklahoma enacted the Uniform Commercial Code and codified it in Oklahoma Statutes Title 12A (Commercial Code). When a page on Lawtopolis cites a UCC section such as § 3-301 or § 9-406, read the matching section of Oklahoma’s enacted code, which may contain state-specific changes.

How to research a case in this state
First, find the statute or rule that governs your issue where you live. State law controls most of these questions, so the answer can change from one state to the next. Next, read recent decisions from the appellate courts in your state. They show how judges apply the law today. Also, check the local rules of the court that would hear your case. Our state procedures guide links to each state’s official rules. In addition, the Research Center explains how to confirm a source is still good law.
