Legal Question in Real Estate Law in Georgia

No one here has the documents you mention, so no one here can possible answer you. You need to read the documents, as they will tell you your obligations. This is the very risk you willingle accepted by entering into this important transaction with a person with whom you have no legal relationship. If you cannot afford the house, you will need to sell (and likely give her half the equity), risk foreclosure, or try to rent the house. This will likely be an expensive lesson to not do this again. Lawyers get many questions about the exect same scenario because they don't work out.

First of all, there is no such thing as a "quick claim deed." Perhaps you meant "quitclaim?"

You jumped into a huge mess in buying a house with someone you chose not to be married to. Certainly a lawyer, had you asked at the time, would have told you not to, or would have drafted documents to deal with it.

At this point you need to see a lawyer and determine your options. They may not be good, but you need someone to review the paperwork and minimize the damage, as you could lose your home.
