(a) The child support and arrearage guidelines issued pursuant to § 46b-215a, adopted as regulations pursuant to § 46b-215c, and in effect on the date of the support determination shall be considered in all determinations of child support award amounts, including any current support, health care coverage, child care contribution and past-due support amounts, and payment on arrearages and past-due support within the state. In all such determinations, there shall be a rebuttable presumption that the amount of such awards which resulted from the application of such guidelines is the amount to be ordered. A specific finding on the record at a hearing, or in a written judgment, order or memorandum of decision of the court, that the application of the guidelines would be inequitable or inappropriate in a particular case, as determined under the deviation criteria established by the Commission for Child Support Guidelines under § 46b-215a, shall be required in order to rebut the presumption in such case.

(b) In any determination pursuant to subsection (a) of this section, when a party has been determined by the Social Security Administration, or a state agency authorized to award disability benefits, to qualify for disability benefits under the federal Supplemental Security Income Program, the Social Security disability program, the state supplement to the federal Supplemental Security Income Program, or the state-administered general assistance program, parental earning capacity shall not be a basis for deviating from the presumptive support amount that results from the application of the child support guidelines to such party’s income.

(c) In any proceeding for the establishment or modification of a child support award, the child support and arrearage guidelines shall be considered in addition to and not in lieu of the criteria for such awards established in sections 17b-179, 17b-745, 46b-84, 46b-86, 46b-130, 46b-215, 46b-569 and 46b-570.
