How hard it is to fight a foreclosure depends to a great extent on where you live. If your state requires the foreclosing party to sue you (this is called judicial foreclosure), then it’s easier (and less expensive) to jump into the existing lawsuit. If, in your state, foreclosures proceed without court supervision (nonjudicial foreclosure), then you’ll have to bring your own lawsuit—a more worky and costly process. (To see which procedure is followed in your state, check the list in Ch. 2 or your state’s page in the appendix.)
