... Imagine you could just call up your bank and say "By the power vested in me, by myself, for myself, effective this date, I owe you nothing, I'm keeping the house, car, land and all contents, and I get full deeds. See ya, wouldn't wanna be ya." Oh and with no penalties to boot. No credit damage.
To me this seems inherently wrong.
Replace bank with husband and unmarried men should be afraid. Very afraid.
