(2) the applicant has made oath or affirmation that the statements contained in the application are true to the best of his knowledge and belief;
(3) the applicant appears from the application to be an interested person as defined in section 30-2209(21);
(4) on the basis of the statements in the application, venue is proper;
(5) any will to which the requested appointment relates has been formally or informally probated; but this requirement does not apply to the appointment of a special administrator;

(7) from the statements in the application, the person whose appointment is sought has priority entitling him to the appointment.
