Why get married Clive?
Why not live in sin like I do??? Met the girl whilst we were both living in England, we travelled out here together & have never needed to get married - we love each other as much (but not quite as often due to older age now) as we did when we first met!! There are certain legalities that might affect you that you might like to take up with a legal advisor (& I am certainly not that), before you splice the knot!!
If you haven't already done so, try placing this request for information on the legal forum too!!
Good luck & watch out for your wallet if you DO get married - Grahame.
