My sons dad has been fighting for custody of my son we now have joint legal custody but I have physical custody of my son... I will be getting married this year but my fiancé is in the military and is stationed in killeen tx what can I do to make sure I can take my son with me?

Hire a good attorney, be willing to work out a very good visitation agreement with the father.

If the sons dad visits often, pays his child support, you are now saying you are taking the child away from his other parent, the judge may allow it, or they may say you can't also.

Hiring a very good attorney is a start.
