reverse quitclaim

I purchased a house in my name for my mom and her common law husband because I had great credit and they were unable to accept financing. Long story short they told me they were getting their house taken away because of IRS liens. I was given the guilt trip that my mother would be out on the streets and my siblings would have no home. The house was only supposed to be in my name for about 1 year until their situation was over with. They still have the house 2 1/2 years later, my wife and I were threatened until I singed over the quitclaim deed over to them so I couldn't sell the house. I was in fear for my life and under a lot of stress. I obtained the quitclaim deed that was signed and filed, they transfered the deed to my 15year old brother. The loan is still active in my name and they refuse to get the mortgage out of my name. I can't afford a lawyer, can I represent myself in court and file the correct paper to get the deed back? I read that since I am the grantor on loan and the mortgage is still valid I cannot transfer the deed, it's illegal. Also, a minor cannot receive a deed if the loan is paid off. What is the quickest way to get the deed back so I can begin the eviction process and have the mortgage foreclose. I want nothing to do with the house. They apparently have been making the payments late since inception, my credit is ruined.
