Well, the site says it's also for couples that are separated OR divorced already. Why not take a shot at it??

On their site it says that "Many lawyers and judges send couples to Retrouvaille as a prerequisite to filing for a divorce or rendering final decisions." so I asked my paralegal about this (in the context of a couple unable to settle their differences after mediation and before the judge made a final ruling) and this is his response: "As for Retrouvaille, I have never heard of that being ordered. There are all sorts of orders that can be made as part of a custody proceeding: Co-parenting classes, therapy, custody evaluations (which are expensive), outside mediation, just to name a few. Retrouvaille appears to be more akin to marriage counseling, though I recognize they don't call themselves that. However, I do not think a court would order it as part of the custody matter, though the parties could agree to it if they wanted."
