A reseal of a Grant is an acknowledgment that a Grant made by the Supreme Court in another State or Territory is valid in the current State or Territory.
The document looks very similar to a regular Grant of Probate or Letters of Administration. It will have the stamp of the relevant Supreme Court and be signed by the Registrar of the Probate office. Depending on the format of the original grant and how you submitted the grant to the court, the resealed grant will have the stamp of the original court, as well as the court where the grant was resealed, and be viewed as one original document.
In New South Wales, Queensland, the Australian Capital Territory and Western Australia, the reseal is issued as a paper document. In Victoria, the reseal is an electronic document that can be accessed online.
