Are civil partnerships still a thing? And perhaps a good idea, if legally allowed, for those traveling to the U.S. I know we in California were advised to keep our civil partnerships even if we are married, because, when and if we travel, only of the two will be recognized in some states.
(The above is up in the air, of course, now that DOMA has been overturned, but why risk a problem?)
The European Union has the same crazy patchwork of marriage equality, civil partnership, total bans, etc., but per the following site, most countries will accept either a marriage or a partnership as the equivalent of what they have (unless they are one of the remaining countries who recognize neither).
