(a)
In general— In rating and underwriting any insurance policy offered by an insurer that takes into consideration the marital status of the proposed insured, the insurer shall consider the proposed insured to be married if the proposed insured is in a legal marriage, a civil union, or a domestic partnership with substantially the same legal obligations and consequences as a legal marriage under the laws of any jurisdiction (including any State of the United States, the District of Columbia, the Commonwealth of Puerto Rico, Guam, the Northern Mariana Islands, the Virgin Islands, American Samoa, or any foreign jurisdiction).
(b)
Right of action— Any person aggrieved by a violation of the requirement under subsection (a) may bring a civil action in a court of competent jurisdiction for damages resulting from the violation, and may obtain other appropriate relief, including equitable relief. If the plaintiff prevails in any such action, the court shall award the plaintiff any litigation costs reasonably incurred, together with reasonable attorneys' fees and reasonable expert witness fees, as determined by the court.
