Legal Question in Real Estate Law in Georgia

If the house was the only thing at risk, she wouldn't need a co-signer. The very purpose of that is so the lender will have someone else to go after for the money. They can sue, get a judgment, and start looking for assets.

Lenders seek cosigners because they believe that the person cannot pay, and they think you can. It is ALWAYS dangerous to cosign because in the event of default or late payments (1) your credit is ruined and (2) you can be sued. That suit can result in garnishment of your pay and bank accounts and a lien on your home, stock and other assets.
