What is my next move?

[Glenn Harris]

Purchased parcel of land and have received warranty deeds back from survivors of the original owner (mother who is deceased). Original and children live out of state and the children never open probate in the state where land is. They were letting it go to auction via tax deed sale. I will be registering warranty deed next with the county. Since the title wasn't conveyed to children, and they have signed over interest to me, would my next move be to retain attorney for quiet title action? I won't be selling property, as it joins my mothers property. Any and all suggestions greatly appreciated.
