Legal Question in Real Estate Law in California

Was the meditation reduced to an order by a judge? If not you should file an OSC and show the mediation to the judge and ask for an order.

Further to what Hong said, if it was made part of an order or a final divorce judgment, then file an OSC re: contempt of court and have him hauled in to explain why he is ignoring the court's order/judgement.

In mediation, there is a fine line between what is private, confidential and inadmissible in court, on the one hand, and what can be enforced, on the other. If the parties have mediated and reached a resolution of some or all the issues between them, it can be put "on the record" and becomes an enforceable settlement as to the things decided. Otherwise, the things said during mediation "never happened" as far as use in a legal proceeding goes.
