I guess there might be some states or counties that REQUIRE counseling before granting a divorce, and suppose in all but some extreme cases (such as those involving abuse/domestic violence) I can't see the harm in a trial separation and counseling prior to the divorce regardless of their being children involved or not.
Counseling might help both sides keep a calmer, cooler demeanor, and allow mediation to be successful, thereby removing the necessity of a messy court battle (especially where children are involved.)

Check to make sure all the boiler valves are open. Yes and also check that the circulator pump is working.
