Purchase Contracts: My Friend Might Be Getting Screwed

I have a friend who is in the process of getting divorced. Her Husband is trying to get her to sign a document related to the purchase of a property. He tells her that it is a document related to changing the property into his name, but it appears that he is trying to get her to co-sign a loan making her jointly responsible for the life of the contract. Please give me your opinion on whether or not she should sign the document and if it seems that she would be liable. Thank you in advance.
