My mother passed away approximately 2 years ago. She did not leave a will, but me and my siblings have signed papers to appoint the eldest sibling as administrator of our mother's estate. We have been approached by our eldest sibling, if we would agree to sign our mother's property in his name. My other siblings disagree with his decision and has decided not to sign any forms to transfer the property into his name. We have disagreed based on his negligence of handling the property with the proper repairs, allowing rent to lapse as well as lateness of paying the taxes. How long can he stay as administrator of the estate?
