Service of notice shall not be required in the case of a person whose interest, even though vested, cannot be possessed until the passage of time or the happening of a contingency. The probate court may, on the motion of any party in interest or on its own motion, modify the service of notice required in the case of numerous beneficiaries of the same or similar class where the value of each testamentary gift is, or appears to be, nominal. Upon the motion of any party in interest or upon its own motion, the court may determine whether the interest of any beneficiary required to be served with notice under this subsection is adequately represented, including any contingent interest of a beneficiary, and if such representation is found to be inadequate, the court may appoint a guardian ad litem to represent each beneficiary or order such other service of notice as may be appropriate to a beneficiary of a contingent interest. If a trustee named in the will indicates a refusal to represent the beneficiaries of the testamentary trust, the court may order that notice be served directly on the beneficiaries of the trust. The provisions of Code Section 53-12-8 shall be applicable to a trust beneficiary required to be served with notice or represented under this subsection.
