Real Estate / Polish law on inheritance and real estate [42]

Hello, my name is Renata, I live in the UK, I was born in the UK to Polish parents, I have dual nationality. My Grandmother left a will leaving my mother land and property in Poland, however my mother whilst she was alive did nothing to put the deeds in her name. Now my mother has passed away a few years ago and she in turn left a will leaving me and my brothers her entire estate. I have copies of both wills ,my Grandmothers and my mothers. The problem I have is my Aunt lives in the property that belonged to my mother and I now want to repossess the land and the property. I did start legal proceedings in Poland a few years ago but the lawyer was not very forth coming with the information. I would like to know how much you charge for your services,
