I'm Admin of Estate with full authority. There's only one heir and myself as beneficiaries. Can I sue that heir?

I don't know who to sue, the other heir or the Estate or both? Reason I want to sue is because there is a property included in this probate that is mine but there's a false deed recorded saying I gifted it to the deceased I DID NOT. Burden of proof is on me and I have ample proof. I just don't know exactly what to do. I want to prosecute and charge the heir double damages for doing all this to me. He changed the deed to my house to his moms name who was dying this way he would inherit the house. He is causing me great financial harm by doing this and he knows it and still he continues so he needs to pay up. I need to file a quiet title action and do an 850 and 859 petition. I need help ASAP! anyone?
