My daughter turns 18 on September 7. My ex just paid for this month a child support of $233.33 instead of the full $1000. Can he do this?

Dear Anonymous:   It would really depend on what your Final Judgment and/or Marital Settlement Agreement says.  It likely states that the child support terminates on the child's 18th birthday (Sept. 7th).  It appears that he pro rated it for the month.  However, check your agreement because the law typically says"...18th birthday or graduation from high school, whichever comes later...provided there is areasonable expectation that the child graduate before her 19th birthday."  If this applies in your situation (daughter in 12th grade and will graduate in June next year) then he would still owe full support until that time. If you believe that your agreement provided for the support to be paid for the full month of his birthday you would have to file a motion with the court  for contempt to get the remaining amount. I hope this helps. Best of luck, Cindy S. Vova Law Offices of Cindy S. Vova, P.A.
