Such application shall be made upon personal notice of not less than twenty days to such convicted person and to the district attorney of the county where the conviction was had, and upon notice to such other persons as would be entitled to notice of application for the probate of the will of such convicted person if he were then dead leaving a will of real and personal property, to be given in like manner as notice of application for such probate. The application shall, among other things, set forth the amount of the property of such person, and the names and residences of his heirs-at-law and next of kin, as near as the same are known or can be ascertained by the applicant.
