“Can my ex sue me for monetary help to provide a car or collage education for my child, in addition to my regular monthly support payments? Would costs of a car be covered in the regular monthly support or could a court grant her money for this? My divorce was granted in Texas.”

In California where I am licensed, the answer is probably not. However if parents agree to certain add-on expenses for the child (i.e. college, piano lessons or a car) that expense is usually split evenly. Consult a Texas attorney about add-on items.
