I really think it should be WAY harder to marry. I remember asking the registrar if there was a list somewhere of what legal changes would happen when I married, what the "small-print" of the contract was, in fact a prior view of the LARGE-PRINT would have been a start. there is no list here.
there should be a long list, in plain english explaining the legal, financial, medical ramifications of tying that knot. and you should have to provide full financial disclosure. and a health-check. and and identity check. and a crime-record check. and a family tree etc, plus undergo compatability counselling, before it is even possible to get a marriage license.
