The rabbinic organization "Bet Hillel" has released a psak.

Bet Hillel has decided that people with financial disputes or civil lawsuits should first bring their suits before a beis din, and only if the other party refuses to appear before the beis din can you then go to the secular courts.

Thank you Bet Hillel for paskening like the Shulchan Aruch and every other halachic source from throughout history.

To be fair fair to Bet Hillel, they are dealing with a thought process that might consider the secular courts of Israel might have the status of "Mishpat HaMelech" - the kings court, and that would mean one could go to be judged before the secular courts without first going to Beis Din.
