bearishgurl — in the Orthodox community, parents are legally married, so both are custodial.
Correct that this won’t fly in expensive cities, but the communities I speak of are often outside of NYC. Typically in the foothills of the Catskills, west of the Hudson.
My point is that this crap happens now on the fringe. If polygamy is legalized, it will keep happening, but remain on the fringe.
From what I understand, polygamy is actually pretty rare in Muslim countries where it’s legal.
