What is the ruling on transferring money to family in another country through two agents, one in each country, such that the delivery occurs at the same moment the transferred amount is received?

If the question means authorizing someone in the inquirer's country to give a sum of money to his family, and upon the family receiving the amount, the inquirer pays the equivalent to the agent of that person in the country where he (the inquirer) is, then this transaction is permissible, whether it is a donation or for a fee. This is because the required قبض (taking possession) in currency exchange is achieved in such cases.
