I've told you already, i think she will have to leave before her visa expires dec 2010, or sooner if the home office tell her to
i don't think the divorce will effect what i've just said, her marriage is over so she will have to find another type of visa to stay here on, or leave when the ho tell her to or b4 her visa expires, which ever comes first, her spouse visa is not valid if their marriage is over .
it will not help that she has been married b4, and the marriage didn't last long, so you will need lots of strong evidence.
you can get married here, but that depends on where she will be and when that will be, and then that will determine what visa she can apply for,
either a unmarried partner visa or civil partner visa..
