Legal Question in Family Law in Louisiana

It not where you live but where the Judgment of support was rendered. YOU DID NOT HAVE THE RIGHT TO MODIFY WHAT YOUR CHILDREN WERE ENTITLED TO! Now that I have yelled at you, you should have understood that it is the Children who have the right to support NOT you. Anyway, if you did not get the court's permission for him to pay $1,100 when he owed $1,600, then you can collect the extra $700 he did not pay. HOWEVER, if you let the Judgment be for $1,100, then that is all he had to pay and owes you $200 a month for every month he paid you less than he was ordered to pay. So back to my first sentence. Was the Judgment in Louisiana and does he live in Louisiana? If both yes, then 10 years, times 12 months is 120 months times 200 per month, so I see that he probably owes you $24,000. That is based on the 10 year limit on back child support. Since both your children are still under 18 then the $30,000 is what you should shoot for. The $24,000 is for sure and you should get a judgment for that amount at least.
