Executors frequently appoint more than one person as his or her personal representative, and on occasion not all parties who are entitled to apply for probate actually do. However at the same time they do not renounce their executor ship and reserve the right to apply at a later date.
If that executor does apply for probate at a later date, the new grant is called a double probate, that runs concurrently with the earlier grant, assuming one or more of the first executors to probate is still living.
The applicant for the double probate includes only the un- administered estate in his or her affidavit. The affidavit must also give particulars of the early grant of probate, and show that the power to him or her to apply was in fact reserved in the earlier grant.
The same notice of intention to apply for probate pursuant to section 112 of the Estate Administration act must be sent to all interested parties again, along with the appropriate supporting materials.
While textbook authors have stated that in theory one executor may apply for a grant of probate without notifying the other executors, in practice it is doubtful that a court would make such an order without notice, as it is important that the executors who are not appointed, reserve their right to apply at a later date, and that the right is specifically stated in the initial grant of probate.
