i think it's called nplua? the new husband paying the first husband because he is marrying the first hubby's estranged wife.
nplua only applies when the wife & man are still married n the wife has an affair.
if the wife n husband is in process of divorce -- she is called nkauj fa. ... if she has an affair during that time then the (soon to be ex) husband still has right to nplua the wife & adulterer. tho she is nkauj fa she is still considered a married woman UNTIL the divorce is finalized between her & husband.
again .. in the case of returning the bride: the mans family must send her back with money (muaj nyiaj ntxuav) + everything that she recieved from her family as cov khoom phij cuam (dowry) . .... some pay equal the bride price, some pay even more, some pay less ... depends on what is negotiated.
if the bride is not happy bc the husbands reason for divorce is not suffcient (in her opinion) or HE is the one at fault (for ex: say like she has done all her duties as nyab well but he has another woman he wants to marry) she has right to voice and demand for more money than what he offers. ... the OGs on both sides should take a closer look at all claims n come to conclusion.
