Transfer of property after separation - De facto

[sandy222]

I purchased a property with my defacto last year Queensland. I paid the deposit and we both paid $1000 each to secure the property at the time. We lived together for 3 weeks in our house before he moved out. He has not contributed to the mortgage repayments and he has since got his $1000 back. The mortgage is in both names which I am now trying to refinance. We both agree that I owe him nothing and he has no interest in the property which is good. I am getting conflicting advice on how to transfer the title to me only so I can proceed with the refinance. Any help would be appreciated. Obviously I don't want this to cost too much
