My wife has a judgement here in Florida from discover card.She is 60 and can't work I'am 67 and on social security.What can they put a lien on?

What do you own jointly and what does she own individually?

We own nothing jointly. She and my sister are on a tilte to our mobile home we live in.
Should my sister take my wife off the title?
Because she is the one who bought this moble home and put my wife name on it because of her husband,who is now deceased.
She didn't want her husband to know, so it is her home.

Thank's
Lou
