To be proper, the court must have subject matter jurisdiction and personal jurisdiction.
In Nevada, the justice court has subject matter jurisdiction over matters where the damages are less than $10,000. So it seems that the justice court has subject matter jurisdiction over this matter.
Next is personal jurisdiction. This is a bit trickier, but essentially it means that you have availed your self to the laws of the jurisdiction where the justice court is located. If you live in Nevada, then more likely than not, the justice court has personal jurisdiction as well.
That being said, however, you could ask the court for a change of venue. If there is another court closer to both parties, that could also have jurisdiction, then you might be able to change venue to the closer location I suggest retaining an attorney, at least for the change of venue issue.
I hope this helps. Good luck.
