I'm going to assume you want that information.
The bill must state sufficient cause. Ordinarily, to establish sufficient cause, a defendant-petitioner must demonstrate: (1) a meritorious defense; (2) justification for the failure
to assert that defense; and (3) that the default judgement was not rendered due to the fault or
negligence of the defendant-petitioner. The petitioner must normally show that he exercised due diligence to assert all adequate legal remedies before filing the bill of review. However, the absence of proper service will not allow the availability of a bill of review.
A bill of review is an equitable proceeding to set aside a judgment that is no longer appealable or subject
to a motion for new trial. Although it is an equitable proceeding, the fact that an injustice may have occurred is not sufficient to justify relief by bill of review. You must show that you exercised due diligence to pursue all adequate legal remedies against a judgment and, at the time the bill is filed, there is no adequate legal remedy available.
You will want an attorney to help you with this. I don’t always say to get a lawyer, but in this instance I would. We aren't allowed to refer to any particular lawyer. However, what I do here, which helps my customers tremendously, is I give you a list of lawyers in your area and I'll show you how easy it is to pick one. I have a short, easy to understand free guide and it will show you what to look for in an attorney. I will also look for LegalAid and pro bono attorneys in your area if you tell me to do that. I just need to know where to look. The bigger the city the better. My customers tell me they have found great lawyers from my information. This part is free of charge -- I do this as a courtesy to my customers here. Just let me know if you want this information.
Does this answer your question or would you like more information?
