In my opinion, I really doubt that they haven't gotten married - even just a small ceremony (maybe just family). Whether it happened September 28th or not, they both - especially harry - just seem like the type to not want to wait. Those videos from the 1d days when Harry would fiddle with his rings and smile when interviewers talked about marriage makes me think that maybe it did happen around then, but definitely not like 2011 when people would show that video of Louis replying to a fan about already being engaged to harry (I view that as a joke). They definitely knew they were it for each other since the beginning, but they might have wanted to wait because it might complicate things even more than things already were. In my head I hope they did when Jay, Fizzy, and Robin were still around to be there, but regardless of the timeline, looking at their lyrics, how they talk about love in interviews (harry talking about feeling like a team once you have been together so long, and louis calling his partner his "other half"), there is no way they aren't married.
I always hoped they'd done something while the three of them were alive, as well. Maybe it was just some informal commitment ceremony because I don't think they were married as of 2017.
For years, I assumed they weren't married because marriage records are public documents. But this morning I was talking to @apparentlybychance about it and looked this fact up, and apparently (correct me if I'm wrong), in France, marriage documents are kept private for 75 years. In Italy, they're public, but you have to know the date and the city where it was performed and request a copy from there.
So... who knows? Maybe they've gotten married in France. Or Italy. LOL! It's fun to consider.
