For the popular summertime weddings those chats tend to happen around now.
Some churches also put on a wedding preparation day at which they might run a couple of relationship discussions/activities, do a fake and truncated wedding service, confirm of adminisrtative stuff and so on.
At the church my wife is a curate at they do all of the above.
She's had quite a few couples come round for a chat - mostly at weekends - and I've made tea/coffee sometimes. Of course I can't hear the detail of what they are discussing - just the general rumble of conversation and laughter as a background noise in the house.
But with that background noise from their conversation - and the amount of time they take for the chat - you can usually tell if they're a chatty or reticent couple and whether it took shorter or longer than usual.
Sometimes the couple can look a bit anxious when they turn up. I imagine some couples think they're going to be given the 9 degrees on their faith and relationship - which is not something my wife would ever do!
