I'm in CA. I took my ex to small claims for $1200 he owed me. We talked to a mediator and settled on $150/month payments because he said he couldn't afford anymore than that (I even asked for $200, and he said he couldn't pay that much). I just found out he is on vacation in Germany right now, obviously not broke enough to only pay $150/month to me. Can I take him back to court to overturn the mediation and get the whole payment, or am I stuck with the mediation agreement?
