Iowa Code § 633.289

After being informed of the death of a testator, the clerk shall notify the person, if any, named in the indorsement on the wrapper of said will. If no petition for the probate thereof has been filed within thirty days after the death of the testator, it shall be publicly opened, and the court shall make such orders as it deems appropriate for the disposition of said will. The clerk shall notify the executor named therein and such other persons as the court shall designate of such action. If the proper venue is in another court, the clerk, upon request, shall transmit such will to such court, but before such transmission, the clerk shall make a true copy thereof and retain the same in the clerk’s files.
