I lost my inheritance because my lawyer got bribed by the opposing side what type of attorney would i need?

What type of attorney would i need to prosecute the attorney that "represented" me and to try n reopen the case regarding property that was not willed to anyone but im a child of the deceased who owned the property? My lawyer took a bribe from the opposing team, stalled till the appeal period ended to tell me the result of the case so i could purposely not appeal so he can get a cut of the property. My lawyer was in "cahoots" with the opposing lawyer. what type of lawyer can i hire to prosecute him and to reopen my case due to my lawyer purposely sabatoging me for HIS OWN MONETARY BENEFIT??
