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 Texas, a Temporary Restraining Order (TRO) is a legal measure used to preserve the status quo by temporarily preventing a party from taking a particular action. It is often used in situations where immediate harm might occur without court intervention. The TRO is granted without notice to the opposing party and is typically in effect for 14 days, as per Texas Rule of Civil Procedure 680. However, it can be extended for an additional 14 days if necessary. To obtain a TRO, the applicant must file a verified complaint or an affidavit that clearly shows the immediate and irreparable injury, loss, or damage that would result without the TRO. Following the issuance of a TRO, a hearing for a temporary injunction is usually scheduled, where the court will decide whether to replace the TRO with a longer-lasting injunction that remains in effect for the duration of the lawsuit. It's important to note that TROs are not final determinations on the merits of the case but are meant to prevent harm until the court can make a more informed decision.
