Based upon your description of the facts, I suspect what happened is that the landlord filed a new
"unlimited jurisdiction" superior court lawsuit against you. In order to qualify to be an unlimited jurisdiction case, the plaintiff must allege damages exceed $25,000. Since a plaintiff has the burden of proof, the landlord must still provide the court (or jury) with admissible evidence.
If you haven't done so already, you need to first file an Answer or General Denial.
Thereafter, you will need to propound written discovery to ascertain what evidence, if any, the plaintiff has. Written discovery consists of form interrogatories, special interrogatories, request for admissions, and demand for production of documents.

If you have documentation that establishes you paid the LL the very money claimed to be owed to him, by you, it would appear that you have a strong defense based on your representation. However, $25,000.00 is a substantial sum, and you want to make sure any legal defenses and rights you have are properly presented to the court, etc. It seems you would be best served if you retained an attorney to represent you a.s.a.p.
