Perjury requires you to know that the statement you made was false, meaning you knowingly lied. If you did not knowingly lie, then you have likely not committed perjury. It sounds to me like you did not know that the statement you made was false, you were going off of records you believed were correct, so you should be ok. If you feel uneasy about the situation, talk to the lawyer you had in your small claims case, if you had one. If not, call up a criminal defense attorney and they can advise you further. Good Luck.
It was obviously an innocent mistake - that is not perjury. If it really bothers you consult a local attorney
This is not intended to be legal advise or as legal representation. I am a California personal injury attorney . Be aware that every state has its own statute of limitations; and statutes & case laws that govern the handling of these matters.
Making a mistake is not perjury.
Since you lost the case, it really doesn't need correction.
