Opening of deposited will
8.-(1) A will may not be opened in the lifetime of a testator except with his consent; and after a will has been opened it shall be re-sealed and endorsed as required by rules 4 and 5 unless a testator revokes such will by endorsement thereon.
(2) A will may be opened after the death of the testator by his executor or other interested person.
(3) No will shall be opened under this rule except in the presence of the probate registrar who must be satisfied of the testator's identity (if alive) or of his death and of the identity and interest of the persons desiring to have the will opened. For this purpose the probate registrar may require evidence as to death or identity upon affidavit.
