 Whereas commercial agreements or prenuptial agreements generally do not require legal formalities to be observed, when married couples enter a property agreement (agreement for the division of property at the termination of the marriage), stringent requirements are imposed, including notarization, witnesses, special acknowledgment forms.In some countries, these must be filed (or docketed) with a domestic court, and the terms must be "so ordered" by a judge.This is done in order to ensure that no undue influence or oppression has been exerted by one spouse against the other.
