The Grant of Probate you receive in the UK may not automatically be recognised by the local court where other assets are held. This means the executor can’t deal with bank accounts, investments, or land held abroad until the local courts grant them the authority.
Likewise, a grant of probate or equivalent from outside the UK might not be recognised in England and Wales.
In some cases, it may be necessary to obtain a separate grant of probate to release the assets held in a foreign jurisdiction.
For an estate with assets in multiple jurisdictions, several different court authorities may be required to administer assets.
