By a last will, either parent may appoint guardians for minor children, or for children, regardless of age, who are judicially determined to be in need of guardianship under the provisions of this chapter, whether living at the time of making the will or born afterwards, and such guardians shall be governed by the laws applicable to guardians appointed by the Probate Division of the Superior Court. If, by his or her will appointing a guardian, the testator orders or requests that a bond shall not be required, it may be dispensed with, unless the Probate Division of the Superior Court judges that from a change in the circumstances of the guardian or from other cause the estate of the ward will be insecure.
