Sure, but marriage is literally a commitment to each other, current offspring, and future offspring. Theoretically a couple could enter an "anuptual agreement", but that's a rare occurrence if it happens at all. A vaguely defined agreement can work fine, sure. But specifically defined and specifically enforced agreements have their merits.
