Marriage contract over the phone!

Question: He says, O Esteemed Sheikh, may Allah grant you success: Is it permissible for me to conclude my marriage contract with my wife’s father over the phone? Answered by Sheikh Fawzān ḥafidhahullāh: No! Not over the phone! It is necessary to be present [physically] during the marriage contract in order to hear the marriage offer and acceptance; the husband, the guardian, and the witnesses must all be present during the marriage contract.
