'Synchronization of flow in UML Sequence Diagram
How to synchronize flow after sending two asynchronous messages?
Solution 1:[1]
There isn't an explicit construct for this in sequence diagrams afaik. You would have to annotate the diagram with a comment/constraint to indicate the need for synchronisation before further action.
Have you considered an Activity Diagram? They have specific notation for parallelism & synchronisation.
