Property, liability, or health coverage that takes precedence when more than one policy covers the same loss. In order to avoid OVER INSURANCE, or paying an insured more than the actual loss, the covering policies accept responsibility for insurance in an established order. For example, if a husband and wife cover each other as dependents in group medical insurance, the injured person's own policy assumes primacy. Therefore if the wife gave birth to a child, her policy would apply to obstetrical and hospital fees up to its limits. Only then would the husband's policy apply, covering the amount that had not been paid by his wife's policy up to the limits of his plan.
