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 harm. It is often used in cases of domestic violence or harassment, where the petitioner needs urgent protection from the respondent. The TRO is designed to prevent the respondent from engaging in certain activities or behaviors that pose a threat to the petitioner, such as contacting, harassing, or coming near them. The order is typically granted without the respondent being present (ex parte) and is intended to last only until a formal hearing can be held—usually within 14 days—where both parties can present their evidence and arguments. At the hearing, the court may decide to issue a longer-term injunction, such as a protective order, which can last for a specified period or until modified by the court. Connecticut law outlines specific procedures for obtaining a TRO, including the requirement for the petitioner to demonstrate immediate and irreparable harm, loss, or damage that would occur before the adverse party can be heard in opposition.
