I was there, too. Once in statutory jurisdiction, the only argument, and on appeal mind you with the Uniform Commercial Code, is with legal jurisdiction where written law is declared in contradistinction to the unwritten law.
FYI, there are laws for common, equity and admiralty, thanks to the constitution, but statutory has only policy. There was a blending of this in 1938. You will get a better idea of why if you research Erie Railroad Vs Tompkins (sp?). This is also the case law that you would use if your friend has to use something to challenge a judgment...any judgment for jurisdiction IMHO.
She can do it and better than a lawyer can because the LAWYER WORKS FOR THE STATE AND THAT IS THE WINNER.

This is going to take some time to absorb but the ideal of the law is that everyone should know the law and those that don't get hurt because of it.
