Legal Question in Family Law in Connecticut

When a document must be served on a party (a divorce summons, a contempt motion, a motion for modification, etc.) the paper is given to a judicial marshal who serves the paper and then signs a document called a "return of service" stating that he/she served the paper on the party on such-and-such a date in such-and-such a manner. That Marshal's Return is then (usually) sent to the attorney or person who initiated the service. Sometimes it is sent directly to the court, but the bottom line is that the court can't proceed with the case (motion, or whatever) unless that Marshal's Return is in the court file.
