Ask a Lawyer and Get Answers to Your Legal Questions
Yes, you need to file a motion to reconsider in order to keep your case on file.
However, if you have received three separate deficiencies from the court, I would really strongly suggest that you retain a bankruptcy attorney to help you with your matter. While it is possible to file a second bankruptcy if your current one is dismissed, you lose a lot of the protections with each successive filing. Filing for bankruptcy is complicated, and most bankruptcy attorneys do not charge very much for their services - you will emerge from bankruptcy in much better financial position if you are represented than if you try to do it on your own.
(I do know that customers do not come to this site to be told "go hire a lawyer" - but you really need one. You can find local attorneys using the State and local Bar Association directories, or private directories such as www.AVVO.com; www.FindLaw.com; or www.Martindale.com (I personally find www.AVVO.com to be the most user friendly).).
