Do I have free range to use my veteran’s affairs compensation money however I see fit without upsetting the courts?

Whether you are referring to an automatic temporary injunction or agreed/contested temporary orders, income is still income. If you have counsel, this, and all questions pertaining to your divorce, should be directed to your counsel. You do yourself and counsel and your case a disservice by trying to bring in information from multiple directions, especially if some of those directions have no knowledge of the specifics of your case.
