German law is more clear about this, as you can retain or attain your own property within a marriage, if you do it explicitly. That's why it's common for one spouse to own the house, and the other the business (the house can't be called up to service business debts, in case of bankruptcy).
Marriage has religious and personal significance for me, protects the interests of my children, and allows for a more efficient increase in wealth, but many people enter into marriage, denying that it's fundamentally a property contract. They confuse the wedding with the marriage.
And other people, who would benefit from having such a contract, don't get one because they think marriage is "just a piece of paper" and don't realize the purpose it has, until they land on the street because they actually have no legal right to stay in the house they were living in.
Or people enter into marriage and then later dissolve it, but instead of simply splitting property and going their own ways with their dowries and whatnot, one is reliant upon *future earnings* to care for dependents, which is just inviting massive money printing, to cover all of these open bills, if the other fails to pay up, skips town, or just refuses to work (or works on the black market).
Marry or don't, but know exactly what it is, what it does, and whether it is prudent.
