I just placed my deceased mothers home under an estate and desire to serve my brother who lives in the home with an eviction notice. The home is in baltimore, Maryland, what is required? What should my notice to him say and How shold I notify my other siblings that I have established mom's prperty under an estate?

First do you have the legal right to establish the estate ?

Does the family member have a lease or other legal right to allow him to live there.

Does this family member have some legal rights to the estate?

Have you just tried to call him and talk to him first about moving ? While perhaps not required legally, it would be a more family or even professional thing to give respect of a phone call to see if he would move without a formal eviction.

Yes I do,I took care of all of her financial affairs. My siblings are none compliant and conversations are not possible. It must be donethus way ti maintain my sanity.There was no lease, my mother allowed him to stay there when she was alive however she's been to deceased since July and he cannot financially maintain the home and now it's a financial burden on my husband and I. This must be resolved.

You didn't answer the question of whether he will inherit a share of the house.

Your wording "I just placed my deceased mothers home under an estate " leaves me uncertain as to are actually doing what is allowed.

Did she leave a will appointing you as personal representative? Whether there was a will, have you applied to the probate court to be appointed personal representative? And, finally, do you have an attorney representing you as personal representative? If you do, your attorney should guide you in evicting your brother.
