How can I make sure that I would not lose my mother’s property?

I have talked to an attorney about this matter and he suggested I do nothing because I would end up paying more for his service than the property is valued at. This is my story 22 years ago. My mother passed on, leaving my sister and my brother behind. Ever since then my grandmother payed her taxes for several years. After I moved to the property, I took the responsibility to pay the property taxes. I need some advice about this matter I would hate to lose my mother’s property where I grew up and my kids grew up. Please help me I don't know what to do.
