An executor, also known as a personal representative in Colorado, does not have the power to make decisions regarding the living arrangements of your mother. They do not act as a fiduciary for your mother until after death. Therefore, they would not have the authority to remove you from your mother's house while she is still living. However, if your sister holds a court-appointed position as a legal guardian or has been granted a general power of attorney, they may have the authority to initiate an eviction process to remove you from the residence. I would suggest speaking with an attorney regarding your situation. If you would like to speak with an attorney at Robinson & Henry, please call us at (303) 688-0944. *The foregoing information is general advice only and should not be relied upon to take, or fail to take, legal action.
