Legal Question in Criminal Law in Colorado

I would seek permission from the court. It will depend on the jurisdiction, judge, bond conditions, etc. The best bet is to file a motion and get the court's permission. If you are on bond, you will likely need the bond person's permission to file with the motion, "consent to travel." If somebody signed as a guarantor (family member, friend) you may also need there consent to provide to the bonds person. Also, some courts will require an "extradition waiver" basically indicating that you will not fight extradition if you fail to return and a warrant is issued.
