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 Connecticut, a temporary restraining order (TRO) is a legal measure used to provide immediate protection to individuals who are at risk of being harmed. It is often used in cases of domestic violence, stalking, or harassment. The TRO is designed to prevent the respondent from engaging in certain activities or behaviors that pose a threat to the petitioner. To obtain a TRO, the petitioner must file an application with the court, and a judge will review the evidence presented. If the judge believes that the petitioner is in immediate danger, they may issue the TRO without the respondent being present, which is known as an ex parte order. The TRO is typically in effect for a short period, usually up to 14 days, until a formal hearing can be held where both parties have the opportunity to present their case. At the hearing, the court may decide to extend the protection by granting a longer-term injunction. It's important to note that violating a TRO in Connecticut is a criminal offense and can lead to arrest and prosecution.
