Before letters of administration are granted on the estate of any person who is represented to have died intestate, the fact of his dying intestate must be proved by the testimony of the applicant or others; and the court may also examine any other person concerning the time, place and manner of his death, the place of his residence at the time, the value and character of his property, and whether or not the decedent left any will, and may compel any person to attend as a witness for that purpose.
R.L.1910, § 6256.
