@Chrissy Gray- It sounds like the attorney is setting the father up for failure. Are the father and son on bad terms? Whenever someone files for bankruptcy, there is an automatic stay of all legal proceedings against that person. This would include any attempt to foreclose on the property. There are stiff penalties for violating the automatic stay. It sounds like the attorney may be trying to get the father to start the foreclosure, then get sanctions against him for doing so. After that, the attorney can get the father to settle by releasing any interest he has in the property.
The proper way for the father to assert his interest in the property is to file a proof of claim in the bankruptcy. There may be other things he can do depending on the facts. This, of course, is not what the attorney wants, as he wants to reduce the number of creditors at issue so that his client can exit bankruptcy with no debts or keep some assets.
