Because Warner gave the house to the young woman?
Unknown at present.
As to the second home Michelle Swing received five weeks ago, it is likely that a probate court will return that house to Warner's estate.
Downtown Nashville property owners damaged by the bomb blast are going to sue for every penny in Warner's estate.
For what reason, and why would a probate court be involved?
Yesterday I read where those quit claim deeds were not signed. If that is true, then they are worthless and she does not own the property.
A quit claim deed only conveys the ownership rights of the person issuing it. (including mortgages, accumulated taxes and other encumberments like you mentioned)
I’ve not seen what you stated in print, but it makes perfect sense.
If Warner did not have clear title to the property the deed would be worthless. And like you said, as close as it was to the bombing his estate would evaporate in lawsuits.
