I am a P.R. of my late husbands estate. The daughter changed locks and removed items and I havent been able to inventory assests. How do I sue?

I am a P.R. of my late husbands estate. We have 2 properties one in his name and one on mine. We both had keys. He lived at my property and we had a shop on the other. The daughter stayed there because her mom sold the house she was in. The daughter changed locks and removed items and I havent been able to inventory assests for over a month. I am evicting her now. Hiw do I reclaim the stole property? How can I enforce my authority? How do I sue?
