Legal Question in Landlord & Tenant Law in California

If the lawsuit in federal court pertains to the manner in which the mortgage was represented to you, the way title was held, or the way the foreclosure auction was conducted, you would file a notice of related cases with both courts. You might also file a motion with the federal court to stay the unlawful detainer proceedings pending the federal court's determination of your contentions. (You might be required to pay a monthly rental value, however.)

There are attorneys who focus on these issues and know them cold. It would be worth your while to retain one.

You would file a Notice of Removal. Federal Court standards are pretty tough so your case may get remanded back to State Court and you could be sanctioned if you improperly removed the State Court action.
