You don't have to give your SS#, but more than likely, if you don't, the other side will ask the Court to order you to and if you don't comply with the judge's order, the judge is likely to kick your case out of court. The other side is allowed to discover anything that could likely be admissible in the case. Presuming you have an injury case, almost all your medical records will be indexed by SS# and they will need the number to get those records. Your income records will be indexed that way too. The other side is entitled to get those records if you are claiming injuries and lost income. Good luck.
