If I filed for Chapter 13 about 2 1/2 years ago ago, when or can I can file for conversion to a Chapter 7?

If you are eligible for chapter 7, your attorney can file a motion at any time asking to convert to a chapter 7. You should discuss this carefully with the attorney before taking this step: there are a number of issues to be reviewed, including whether you are eligible for a chapter 7 discharge, and the effect a conversion would have on any assets you own.
