Right to intestate’s property, when established. Except as hereafter provided, but subject to section 4 of the Administrator General’s Act, no right to any part of the property of a person who has died intestate shall be established in any court of justice, unless letters of administration have first been granted by a court of competent jurisdiction. 192. Effect of letters of administration. Letters of administration entitle the administrator to all rights belonging to the intestate as effectually as if the administration has been granted at the moment after his or her death. 193. Acts not validated by administration. Letters of administration do not render valid any intermediate acts of the administrator tending to the diminution or damage of the intestate’s estate. 194. Grant of administration where executor has not renounced. (1) When a person appointed an executor has not renounced the executorship, letters of administration shall not be granted to any other person until a citation has been issued, calling upon the executor to accept or renounce his or her executorship. (2) When one or more of several executors have proved a will, the court may, on the death of the survivor of those who have proved, grant letters of administration without citing those who have not proved. 195. Form and effect of renunciation. A renunciation may be made orally in the presence of a magistrate, commissioner for oaths or justice of the peace or by writing signed by the person renouncing, and, when made, shall preclude him or her from ever thereafter applying for probate of the will appointing him or her executor.
