My father died without leaving a will. He owned a free hold property (self owned) which is to be given out on rent. We are two sisters and one brother (mom has also passed away). We have given the power of attorney to our brother for the said property. Is my brother eligible to execute the rent agreement with the tenents based on power of attorney? or do we sisters need to do a relinquish deed in favor of brother first and then he can do lease aggreement? Please advice.
