(a) The Commission for Child Support Guidelines is established to issue child support and arrearage guidelines to ensure the appropriateness of criteria for the establishment of child support awards and to review and issue updated guidelines every four years. Such guidelines shall ensure, subject to § 46b-215c, that current support, health care coverage, child care contribution and orders of payment on any arrearage and past due support shall be based on the income of both parents and the obligor’s ability to pay. Such guidelines shall also ensure the appropriateness of periodic payment orders on arrearages when the obligor (1) is the child’s legal guardian and resides with the child, or (2) is not the child’s legal guardian but has resided with the child either for at least six months immediately preceding the order of payment on the arrearage or for at least six months of the twelve months immediately preceding such order. In such cases, the commission shall consider exemptions similar to those in the uniform contribution scale adopted pursuant to § 4a-12. Updated arrearage guidelines shall be issued at the same time as the child support guidelines.

(b) The commission shall consist of thirteen members as follows:

(1) The Chief Court Administrator, or the Chief Court Administrator’s designee;

(2) The Commissioner of Social Services, or the commissioner’s designee;

(3) The Attorney General, or the Attorney General’s designee;

(4) The chairpersons and ranking members of the joint standing committee on judiciary, or their designees;

(5) The Child Advocate, or the Child Advocate’s designee;

(6) A representative of the Connecticut Bar Association, designated by the Connecticut Bar Association; and

(7) Four members appointed by the Governor, one of whom represents an agency that delivers legal services to the poor, one of whom represents the financial concerns of child support obligors, one of whom represents the Commission on Women, Children, Seniors, Equity and Opportunity and one of whom represents the rights and best interests of children.

(c) The Commissioner of Social Services shall convene the commission whenever a review is required to issue updated guidelines pursuant to subsection (a) of this section and shall provide staffing for the administrative and regulatory responsibilities of the commission and, within available appropriations, funding for economic studies required by the commission.

(d) The chairperson of the commission shall be elected by the members of the commission. A vacancy on the commission at any time shall not invalidate any actions taken by the commission during such vacancy, provided at least nine members of the commission are serving at the time of such action.
