Not to my knowledge. I believe this is something that must happen in person, regardless of jurisdiction. You both have to consent to the marriage for it to be legal and I don't personally know of a way this could be done in absentia. Sorry.
But it's just my opinion) For me, traditional dating is better! But I work a lot and sometimes I don't have time for traditional dating! So also can use online dating and I do it just for good time spending. But I know a few real stories when people met at dating sites and after that-get married. But I'm not sure that It'll happen with me and I'll meet my future wife in online) But who knows))))
