I agree with TrainTrac,
Do a check on marriages and see if you can find if he was actually married on the day before the court date. Remember that he may have gotten married in a different city, county or state...so not finding the marriage recorded may not be such a cut and dry proof that he did not get married. It might be good to ask for proof in court, since it did cost you a day of work, and it might show this guy is just trying to try your patience...and the court's. You might even be able to ask the court to verify his excuse for missing the original court date?
As for suing for wasting your time taking off work to go to court, unfortunately you cannot normally sue for that, but I would now add it to my countersuit to make sure the judge knows that he failed to show up on the previous court date, and it is costing you more money.
This may be a game this guy is playing by not showing up in court and later coming up with an excuse to reschedule, knowing that you are taking off work and that is costing you money. If the Judge knows this, perhaps there are some exceptions if the Judge feels that the Plaintif is just trying to drag it out to cost you money, hoping you will give in and just pay him. If the guy does not show up this time, I would definitely ask the court to dismiss the case and award you payment for your lost wages...be sure to bring pay stubs to prove your wages, and if possible, your pay stubs for the time period where he fail to show up for the previous court date.
PS: Be sure to check the dates on any documents he submits, ie: repair estimates, etc. If they occurred after the previous court date, he may have wanted to reschedule the court date because he did not have his case ready, and you might get the documents thrown out. It could also indicate that he has added things after the lawsuit was filed, or that he was intending to defraud you from the begining. That might also show he lied about the reason he used for missing the previous court date??
Good luck,
