You have not disclosed whether your brother inherited an interest in the property, why he should leave the premises or what your position is. Generally, in the US, title to real estate passes to heirs at the moment of death. As soon as the estate is filed for probate legal title is perfected. As an heir your brother may have the right to the use and possession of the property. You may add more details on the discussion page.
A deceased person could have their life estate property revised. It is best to seek the advice and assistance of a lawyer.
