The decedent and his wife, the appellant, executed mutual wills that were mirror images of each other. The couple was childless and wanted their assets to be shared equally by their respective relatives. Accordingly, simultaneous with the execution of the wills, they executed a written contract which prohibited either party from revoking or changing the wills in any way, without the written consent of the other, and they further provided that any attempt to do so would be ineffective as against the claims of the legatees of the mirror wills. The wife survived the decedent, whose will is the subject matter of this appeal. His will provide a portion of his estate would be placed in trust with the income therefrom to the appellant for life, and the remainder to their relatives, who were enumerated in the will. The decedent bequeathed the rest of his estate to the appellant outright.
After the decedent’s death, the appellant wife, alleging that she could not find the decedent’s will, applied for and obtained letters of administration. As the sole distributee, she received the entire net estate. The petitioner (hereinafter the proponent), a co-executor and co-trustee under the will, commenced the instant proceeding against her to revoke the letters of administration that were issued to her, and to admit to probate a conformed copy of the decedent’s will or, alternatively, for specific performance of the aforementioned agreement.
