My statute of 3yrs will expire on 8-22-14. If I file a claim within the next couple of days, will the claim be valid if the court date is past the dat

The Court date doesn't matter for limitations purposes, just the date the claim is interposed which (depending on the jurisdiction; I don't know about NC) can be either the date the action is started in the Court or the date the defendant is served.  You will need to prove ownership, and while your testimony may be sufficient, having an objective witness couldn't hurt.  Documentation (receipts, invoices, etc.) would be even better.
