Following the flurry of activity across the internet discussing Egypt's law that would allow a man to have intercourse with his wife for up to six hours after her death, at least one author delved into a discussion of other weird marriage laws.

One I found particularly interesting was the discussion of the fact that apparently, apart from the Vatican, the Philippines is the only sovereign state in the world that does not legally recognize divorce as a way to end a marriage. As a general matter, the Philippines recognize only annulment, or presumably death, as valid ways to end marriages. The reason for this disallowance of divorce is based on Filipino view that the family is sacrosanct and that divorce is destructive of the family unit.

There are, however, exceptions to this law. For example, Muslims may be permitted to obtain divorces according to their religious practices.

Additionally, The Family Code of the Philippines states:

Where a marriage between a Filipino citizen and a foreigner is validly celebrated and a divorce is thereafter validly obtained abroad by the alien spouse capacitating him or her to remarry, the Filipino spouse shall have capacity to remarry under Philippine law. 

Thus, if a Filipino marries a foreigner, and the foreigner obtains a divorce abroad, the Filipino government will recognize the divorce as valid.
