I don't even think the above is possible - at least in my county in MO.
When you file something at the courthouse, you fill out the request for service while you're standing there, and it gets attached to the copy of the filing that is for the other party. That is then turned over to the Sheriff's department.
If I were OP - and what I've done in the past - I would call the Sheriff and ask if they have any pending documents to be served to me. If they do, offer to go pick them up, or let the office know when you will be home to accept service. OR, go to the courthouse, explain to the clerk that you know something was filed, but you haven't been served, and you'd like to accept service of the documents there.
It's a heck of a lot easier to be proactive about it than it is to hope that because you weren't served, the case won't be heard. I've been served literally HOURS before a hearing and it still took place.
