Marital divorce is a serious matter. Marriage is a contract between two sovereign parts. Religious view on marriage is for religious sentiments and contracts. Marriage is a public contract. A breach of this contract will carry compensations. A fifty-fifty split of assets like house, car, cabin, boat and more is not a precise economy. Compensation needs to come into the picture.
The traditional example is that a man leaves a wife and two children. There will be the fifty-fifty split of assets, but the compensation has to be for costs of adapting to a new situation for the family. The mother needs compensation for extra workload, children need compensation for loss of companion and learning. There will be many details to consider, but we are already looking at a 3/4 split in favour of the remainers. Anyone breaking a contract should not be allowed to take anything away from a family.
Short term marriage contracts could be practical. One view is to be married for twenty-five years until the children are fully grown. We could have various contracts to cover any situation of shared assets. What is up for change is the way men and the UK are trying to gain from exiting a union.
We may even look at how family heritage can be improved because this concept is as old as tribal mankind.
