The fees charged by agencies and the extent to which they are
regulated by State authorities vary from State to State. Regulation
is ordinarily determined by administrative rules, regulations, and
standards, not by statute. Very few States specify a dollar amount
for agency fees or specific services that agencies provide. In most
States, the statutes simply authorize agencies to collect
"reasonable and customary" fees for the adoption services provided.
The services that agencies typically provide include preparation
of the pre-placement and post-placement home studies of the adoptive
family; a social and medical history of the birth family; and birth
family counseling. Sometimes agencies also will receive payment for
birth parent expenses and make appropriate disbursements. In
addition, in some States, agencies are allowed to factor a portion
of their administrative costs into their placement fees.
