§ 20-4-176 — Choice of law

(a) Except as otherwise provided in subsection (d) of this
section, the law of the issuing state or foreign country
governs:
(i) The nature, extent, amount and duration of
current payments under a registered support order;
(ii) The computation and payment of arrearages and
accrual of interest on the arrearages under the support order;
and
(iii) The existence and satisfaction of other
obligations under the support order.
(b) In a proceeding for arrearages under a registered
support order, the statute of limitation of this state or of the
issuing state or foreign country, whichever is longer, applies.
(c) A responding tribunal of this state shall apply the
procedures and remedies of this state to enforce current support
and collect arrearages and interest due on a support order of
another state or foreign country registered in this state.
(d) After a tribunal of this or another state determines
which is the controlling order and issues an order consolidating
arrearages, if any, a tribunal of this state shall prospectively
apply the law of the state or foreign country issuing the
controlling order, including its law on interest on arrearages,
on current and future support, and on consolidated arrearages.
