A friend I know just went through a divorce and would like advice on how to protect her social security?

She's struggling with the many complications that her ex-husband is causing. He's pretty much a jerk and has left her stranded. She's Vietnamese and doesn't speak fluent English so it's been difficult for her to deal with the laws and regulations. Unfortunately, I don't know enough about these kind of situations to help so that's why I'm here.

So here's the issue:

1.) During their marriage, he opened credit lines under her name/social security. She doesn't know much about credit cards so at the time she allowed her husband to deal with all of that. Now that they're divorced, she just found out that she has debt under her name, and that her accounts have been turned over to the collection agency. She was unaware of how many credit cards he opened. He's pretty much turning a blind eye and disregarding all of it. What should she do about this?

2.) How can she keep her social security safe so that he can't open anything under her name?

Please keep in mind this woman does not have much money or a lawyer. The more information the better, I would really like to help her out. She's a good family friend and really nice. Not only that, but they have two children together (a 2 year old and 11 year old).

Thanks.
