Misrepresentation in Chapter 13 bankruptcy cases, and pretty much all bankruptcy cases, will understandably be met with disapproval by the court judge. Even if a Chapter 13 attorney is not specifically needed in adversary court proceedings, they may be a ticket to avoiding them as an outside consultant.
Oftentimes, through Internet search engines and other media, providers of a certain function, such as one to help remove all debts and avoid foreclosure, will offer their services for a fee, but they may not be a reputable organization. A qualified Chapter 13 bankruptcy attorney would certainly be able to tell the difference between a trustworthy enterprise and a shady operation.
Along similar lines, a Chapter 13 attorney is more apt to have a handle on how to correctly and legally fill out all bankruptcy petitions.
