But what about a real site? Mail-order-bride sites are legal under international law, as long as the bride is of age, says Andrea Bertone, the director of HumanTrafficking.org. And depending on state laws, requiring a specific dowry for an underage girl—with parental approval—would appear to be just fine. But at some point, dowry crosses over to bride price crosses over into selling—which crosses over into trafficking. “It's complicated, because child marriage is quite common around the world," says Bertone, whose research center is based at the Academy for Educational Development in Washington. “It might be interpreted under the U.N. Trafficking Protocol to be illegal (although there is nothing in the U.N. Trafficking Protocol or the U.N. Convention on the Rights of the Child that mentions anything about marriage or brides), but there is little that can be done if countries do not outlaw it and then enforce their own laws.”
