He is the primary provider and also fathered Atreus solo. The courts may also take into account that he climbed Mt Olympus barefoot and slayed hades. Which makes his work ethic higher than yours. Courts will side with him in matters of child welfare. He most likely will take your home either judicially like adults. Or by force. Prenup protects this.
However.
If you sign a prenup. You can't push to aquire his 3 headed dragon, his axe that uses powers of greek gods coursing through pulsing blue energy pockets to always return when thrown through demi god immortal skull and of course his ragnorokian armor plates made of endangered pelts of arctic beasts he slayed years prior. Which he may or may not retain depending on if you decide to blackmail him with a domestic violence angle. As he has attacked maybe 50,000 people before. Judges side with this. (Please note Kratos never layed a hand on you. He was a dignified gentlemen) f you play the long game. And photograph instances when atreus was in danger. Which isnt hard to do. And dont sign a prenup. Kratos may face his most dreaded boss yet. Divorce court litigator. But thats what we call in the private sector. "Mud ball" and babe ruth never did play that way.
Courts will grant you a permenent restraining order if he does decide to get boisterous. And will consider him a flight risk.
Id sign the nup. I dont know the man so close as yall do.
