Legal Question in Criminal Law in Texas

Re: How do I file a bond reduction.

The form you are seeking is called a Motion to Reduce Bond. You can probably find a form of the Motion at your local County Law Library. You could also file a Writ of Habeas Corpus, but I would probably not use the Writ until I exhaust all my other options first. However, since I don't know any of the facts of your husband's case, I would recommend that you seek the assistance of a criminal defense attorney in your area.
