Spanish Civil Marriage Laws Revamped

MPs in Spain have drawn up a marriage contract for use in civil ceremonies which obliges men to share household chores and the care of children and elderly family members.

Unfortunately, I think the BBC's usually good, in-depth, reporting has been somewhat marred by this one. What they missed is the opportunity to comment on the fact that this law only affects CIVIL marriages. Spain is a predominantly Catholic country--80%, according to Wikipedia--meaning that I expect at least 80% of the marriages in the country to be religious ceremonies, and therefore not bound by a civil marriage contract. 93.4% follow some religion, leaving only some 6.6% likely to have civil marriages.

Two other comments: I hope that standing civil marriages are grandfathered in, because some people might have chosen NOT to marry if that were the requirement. And I wonder if the law obliges women to take 50% of the house chores? That'd be a bummer for me. :-P
