A divorce may be granted forthwith when either spouse has become permanently incapacitated due to a mental condition or psychiatric disability. A divorce shall not be granted under these provisions unless such person who is permanently incapacitated due to a mental condition or psychiatric disability shall have been duly and regularly confined in a psychiatric hospital, wherever located, for at least five years next preceding the commencement of the action for divorce, nor unless it shall appear to the court that such mental condition or psychiatric disability is permanent. No action shall be maintained under the provisions hereof unless the libelant is an actual resident of this State and shall have resided therein for two years next preceding the commencement of such action. (Amended 2013, No. 96 (Adj. Sess.), § 70.)
