i think it should be belongs to the couples.
in our local traditional,boy's family pay for the down payment of the house,and the girl's family pay for the decoration,electrical equipment,house furnishings and so on.
it is unfair to the girl.
Different situations different treatment.
If the women aim to the house or money,i think she should gain nothing,many of the family buy house though their parents,especially the man's family.
But if the man's fault,the woman will gain compensation.
if you care your lover more than his possession, the new regulation or old one isn't important.
i think the point of marriage is lie in making happy to each other not house,car or money.
wealth is gained by our effort so when we are young we should find an appropriate person then hard work to get the life better and better.
