A temporary restraining order (TRO) is a court order requiring the parties to whom it is addressed not to engage in certain activity, or to continue to engage in certain activity, and is usually designed to maintain the current state of things (the status quo) until the court has the opportunity to hear a more complete presentation of the evidence—usually during an application for a temporary injunction that will remain in place while the lawsuit is pending.

In Massachusetts, a Temporary Restraining Order (TRO) is a legal order issued by a court that requires one or more parties to refrain from certain actions or to continue certain actions temporarily, usually until a hearing can be held. The purpose of a TRO is to preserve the status quo and prevent irreparable harm before a more comprehensive hearing can take place. TROs are often used in situations involving domestic violence, harassment, or where immediate harm is threatened. To obtain a TRO, an individual must file a request with the court, often including a sworn affidavit detailing the need for immediate protection. The court may issue a TRO without the presence of the other party (ex parte) if it deems that there is a substantial likelihood of immediate danger or harm. A hearing for a longer-term order, such as a preliminary or permanent injunction, is typically scheduled shortly after the TRO is granted. The specific procedures and requirements for TROs can be found in the Massachusetts General Laws and the rules of the local court where the order is sought.
