That is actually quite clever. I need a near-future world not changed utterly beyond recognition that essentially makes women the wards of men – rather like children in fact. Mistreatment and abuse viewed the same way as we’d view someone abusing a child in their care. The concept of making the family the defining social unit rather than the individual is the best idea I have seen so far.
Reestablishing elements of the legal concept of Coverture from the 19th century under which husband and wife were one person as far as the law was concerned. Women and girls subject to coverture have their legal identities subsumed under men’s, first by their fathers and then by their husbands. Under its strict terms, females submitting to it cannot own property, participate politics, serve on juries, write wills, sign contracts, make legal complaints, or exercise custody rights over their children if their husband or farther objects.
Still can’t find a post WWII POD. Think I’ll have to bite the bullet and go back further. Mormonism replaced by another religion putting enormous emphasis on keeping women in their proper place.
Coverture was never actually that strict, it mainly applied in the area of property law (and only in property law, if I recall). Some of the other stuff you mentioned happened (e.g., women didn't serve on juries) but it wasn't because of coverture. You're looking at something more like the early Roman legal arrangment, and even that was much less strict in practice than it was in theory.
But the main problem is that very, very few societies have been that strict, and Western and other developed societies in particular have almost always moved in the direction of more rights and privileges for women, not fewer. Replacing Mormonism isn't going to come close to coming close to getting the kind of society you want.
With a POD of less than five hundred years ago, I think the only way this is possible is some kind of sex-selective disease that drives women crazy or makes them sexually indiscriminate or just plain kills them (making the surviving women too precious to be free) or something equally within shouting distance of ASB.
