The only thing which is enforceable is a court order. A mediator's recommendation is not an order. If the judicial officer adopts the recommendations, or part of the recommendations, only those parts adopted and signed off by the judicial officer will become enforceable.
Generally speaking, mediator's reccomendations (in "reccomending" counties) are just that: reccomendations, and not orders. You should review the orders with a competent family law attorney, to make sure you are clear on what has and hasn't been ordered.
