1.) A few things here - first, they can't just mail you notice for a motion and have it set on the docket and heard that fast unless a local rule allows it. Most local rules for motions require that is be filed pursuant to KSA 60-206, which requires 7 days, but if served by mail, add 3 days. So if he mailed the motion, did not include the supporting affadavit (DRA), and did not allow the correct amount of time, you can have his motion continued based on that fact alone. But, since you'd like to request continuance to seek counsel, they should allow that as well. You should send a certified letter (return receipt) to the attorney to request continuance to some date citing only that you'd like to seek counsel. Keep the technicality in your back pocket for the hearing. You probably won't receive correspondence, so you make sure that you have the return receipt with you at the hearing. Prepare to have your motion on reimbursement ready for hearing, and be ready to argue very hard to have his motion continued so you can confer with counsel (ask for 2 weeks).
2.) Attorneys are bound by the same laws as Pro Se. Attorneys just get away with breaking the law because they have a rapport with the judge. Many Pro Se's are either not savvy enough or knowledgeable enough to confront an attorney in front of a judge on a technicality such as this one. If you say on the record that persuant to KSA 60-206 subsection (c), the attorney is required to serve the DRA with the motion, and it was not, you can request it dismissed or you can request it continued.
It sounds as though this attorney is trying to take advantage of a Pro Se, which is pretty common. Keep in mind that all district court hearings are recorded, so make sure you mention statutes and local and supreme court rules which have been violated. By doing this, the judge knows that if he doesn't play by the rules, his judgement can easily be overturned on appeal. Your gut is correct that this attorney is not sending motions pursuant to statute. So, you should look for counsel if you want it, but also you can ask for continuance or dismissal of his motions.
You should also look for a notary stamp and a file stamp on the DRA. If he says that he filed it, he should have a file stamped copy dated the same as the motion. BUT, sometimes attorneys don't really file the DRA until the day before the hearing. That's fine, but they still have to serve it on you with the motion. As you know, the DRA must be notarized. That's just another way you can have it thrown out on technicality.
