Hi, we are about to transfer monies from sale of UK property to Australian bank account using one of the foreign exchange companies ie wise or torfx. Once monies are in solicitors hands can the money go straight to a forex company for transfer to Australian bank account or do we have to involve a UK bank to deposit monies in forex company. We dont have a UK bank account and dont really want to go down the path of opening a Uk bank account. Thanks in advance for any help
