Need Some Advice

My husband died with no Will or estate. I have resided in the house for a year and paid the mortgage. He has two daughters from a previous marriage. I have not put the house in probate because I wanted to be financially set able to take over the mortgage payment I am the successor of interest and I was legally his wife when he died. His daughters have stolen all of the property drained my bank account taken his cars that have been reloaded. I have documentation, but they just went and filed for probate I’m in the state of Michigan I do believe They’re entitled to 20 or 25% however, I just want to know if their actions of having the vehicles their threats, their PPO’s the storage unit they have of all my husband’s belongings. Will that come in to play during Probate and is there anything that I should do or be aware of plus I rented the house out so I have two rental tenants right now They assumed I was at someone’s house and sent the court paperwork there not knowing where I’m at. I do not want them to know what address I’m at so if I send this back to the court with return to sender, how does that work because if I got the paperwork, then they obviously know where I’m at and then the chaos in the threads and all that began. I’m sorry this is such a mess. I just I don’t know what to do.
