In my divorce agreement it clearly states, "The parties agree that if at anytime they are unable to resolve their conflicts with respect to financial or visitation issues they will mediate such issues prior to any litigation." It has been over 10 years and my ex husband has never said a word to me about there being a problem with either of these issues. A few days ago however, I was served with papers stating that he is bringing a lawsuit against me regarding child support & visitation issues. He has hired a lawyer (which he is wanting me to pay for-I certainly cannot afford) and it says I have 20 days to respond. -Is there a way to enforce the fact that we agreed that we would first go the route of mediation? How do I do that if he has already filed papers to the court through a lawyer?
