If there is a warrant out for your husband's arrest, there is nothing you can do. You should either go to a bail bondsman right away, post the bond and then have your husband turn himself in at the jail. This will avoid being caught by surprise. If it is a domestic violence case, he may want to see the Judge at initial appearance so you can be present. The Judge will probably order no contact between the 2 of you so you should be there to tell the Judge that you want contact with your husband. Finally you can file a motion to reduce the bond or withdraw the warrant. If you can get a court hearing before your husband gets arrested this may be helpful.
