Does a new Texas family mediation agreement mean the old custody and support order is null/vacated?

The new agreement takes the place of the old agreement as long as it covers all the provisions required in an order. A final order modifying the old order needs to be drafted based on the Mediated Settlement Agreement. Sometimes, the provisions of a previous order are still in affect if they are not modified by the new order. However, in this case, the provisions for no child support would replace the previous child support order. (Be aware that in some counties, the attorney general will contest this type of order if the child is on Medicaid.)
