Legal Question in Family Law in California

That's not an issue I've encountered before, and I don't have time to research it, but I can't imagine that registering a domestic partnership would not have the same effect as remarrying. The whole point of the domestic partnership law was to satisfy the equal protection demands of same-sex couples who were not allowed to marry. So a registered domestic partnership carries with it the same bundle of legal rights, responsibilities and effects as a marriage. It would, therefore, make no sense for registering a domestic partnership not to have the same effect on spousal support as remarrying.
