(d) If the petition is granted, the trustee shall send the notice of removal of the trust provided in subdivision (b) of Section 17351 and file proof of service as required by subdivision (c) of Section 17351 within six months and seven months, respectively, from the date the petition is granted. A copy of the court order granting the petition shall be attached to the notice.

(e) If the petition is not granted, the trust shall continue to be administered under Article 1 (commencing with Section 17300) as if the settlor had provided in the will that the court does not lose jurisdiction of the estate by final distribution.
