$25K is not a small claim in any of the states, is it?
When I looked into small claims court, in California. It was any claim <= 10k. You also needed to legally serve the defended with a non involved party.
That means for equifax, not being a california party, you gotta pay someone to send docs to their legal representation.
It appears to me that Equifax can be sued in California by serving their local representatives in Sacramento.
