Washington Model Stipulated Protective Order (MSO) is a court-approved agreement between parties in a civil case. It is designed to protect the confidentiality of sensitive information that may be disclosed in the course of a litigation. The order is used to ensure that confidential information is not disclosed to any person outside the parties involved in the case, and that it is only used for the specific purposes of the litigation. The MSO is usually negotiated between the parties and approved by the court. It sets out conditions for the use of confidential information, such as who can access the information and how it can be used. It also applies to the attorneys of the parties, and may require them to take extra steps to protect the confidential information. There are two types of MSO: Standard MSO and Limited MSO. The Standard MSO is the more comprehensive of the two and applies to all confidential information disclosed in the course of the litigation. The Limited MSO applies to specific categories of confidential information or parties, and is usually tailored to the particular case.
