Whilst the statistics are limited the data below shows that some people have regret about not entering into a pre-nuptial agreement prior to marriage.  Of course, this does need to be weighed up against the regret one might have by asking for a pre-nuptial agreement if it dampens the engagement! Many people don't address the issue as they wish to avoid that "awkward" conversation, but it could make life far more settled moving forward to have that difficult conversation ahead of time.
