At common law, ne exeat (Latin "that he not depart") is an equitable writ restraining a person from leaving the jurisdiction of the court or the state.
[1] The full phrase in the United States is ne exeat republica (Latin "let him not leave the republic").
[1][2] In 1969 Mr Justice Meggary affirmed that the order still exists under English law, and was not repealed by the passing of the Debtors Act 1869.
[3] It is used in family law to prohibit a person from leaving or removing a child or property from the jurisdiction.
Mr Justice Mostyn said in 2012, "The writ ne exeat regno is a charming historical relic but must be regarded as an anachronism given the availability of the modern form of order".
