When a divorce or legal separation case is filed and served in Colorado, an automatic temporary injunction immediately restrains both spouses from moving children out of state, hiding or transferring assets, canceling insurance, or harassing the other party. Because it activates at filing, plan ahead by finishing any legitimate, ordinary-course transactions and gathering documents so you are not accused of violating the injunction. Build your timeline so important changes like switching insurance or closing joint cards happen either well before filing or with written consent. Keep proof of routine expenditures and maintain the status quo on big financial moves unless you get a court order. If safety is a concern, document it and talk with counsel about coordinated filings and protection options. You can read the injunction notice on the state summons form and the statute that authorizes it.
