Minneapolis Foreclosure Help

What to do with no written notes?
In 2006, I helped a friend of the foreclosure, medical bills, insurance costs, mortagages paid by lending him $ for personal expenses. Finally, I asked to live with me (do not pay a penny, as it was physically sick). So I called and tried to sell the house and pay all over again. (It even gave me the house, but as a friend, I could not do that) while she was living with me, did not work. I was paying bills and expenses made on my credit card (to help other people!). total was $ 15,000 (I have a receipts for the amount few minor). He moved out in a bad term. They've been saying a lot of negative things about me. I checked on his house and found it was sold before they move in with me. So sick to my stomach that a friend called me fooled. How I can get my money? I live in Philadelphia who is now living in Minneapolis. Note: I barrow bank about $ 9,000 to bail out of foreclosure. Please advise.
The Lawyers like to say that a verbal contract (or pay) is not worth the paper it is printed. Ja, ja. The lawyers were never very nice. If you can prove in court costs were executed her and she accepted his help in the form of loan and promised to pay back (Did anyone else hear that promise?), it is possible I can get the refund. However, especially in view of the geographical separation and feeling bad, probably spend more time and money that would again. I suggest you load up the experience and accept my pat on the back for trying to be a good guy.
