Marriage is 50-50 at least going by the vows. Unless there is a pre-nap.
The court should just make that a hard rule...
No need for all these common sensical cases to clog court system...you do not need a court to know marriage is 50-50 - doesnt matter if you win a lottery - it's 50-50.
The basic structure of 50-50 is the couple promise to share everything...you cannot quantify things couple do together...all the wealth created together...even if one was absent is 50. Even if the wife get sick...goes into comma...come back 20yrs later...and want a divorce..she get 50 percent. The same for husband.
Even Kispigis culture recognise that - even if you wife disappears as long as you did not divorce..it's 50-50.
to have and to hold from this day forward, for better, for worse, for richer or for poorer, in sickness and in health, to love and to cherish, 'til death do us part, according to God's ordinance; and thereto I pledge thee my troth.
