I filed for chapter 7 Bankruptcy and it was Discharged on October of 08. It included a property that I had. I have been out of the home for one year. And today I received a summon from the court stating that I have twenty days to reply or I'm going to be sued. Don't know what this means? Does this mean the house is still mine? If I wanted to try to get the home back can I? And if I can't can I ever buy a house again?

Incorrect! Truth in lending laws and fair debt collection practices in our free society date back for centuries. In our country these laws were based on English commonlaw and the end of feudal serfdom. Our country is full of protections of freedoms and is one where landownership is so protected. Laws require judges act to protect the rights of the property owner from acts of robber barons as late in this country as the taming of the wild west and the taking of the land for the railroads.
So in order for the title to that property to change hands the court has to notify everyone on the deed, even though another court (the bankruptcy judge) said its okay, you've disposed of the property in chapter 7. Ironically, the same thing happened to me the same year, I called my attorney in a panic and his advice was what I'm giving you: ignore it.
