Married At First Sight UK: Do couples get annulled, divorced or are the marriages fake?

ok.co.uk:

Married at First Sight UK has definitely done what it set out to after promising a re-vamped season full of drama. As everyone's hooked on the E4 dating experiment and all its couples, fans can't help but wonder about the ins and outs of the marriages, and whether or not the stars have to go through a proper divorce.

We all watched on as the sixteen singletons knowingly committed to marry a complete stranger, which isn't exactly a decision which should be taken lightly.

However, a few weeks in and the cracks proved too much for a few of the show's newlyweds, as they chose to part ways following the show's commitment ceremonies.
