From the NY Times -

Under Michigan’s law, commercial surrogacy is punishable by five years in prison and a $50,000 fine. Ms. Baker said she did not carry the children for money and was reimbursed only for actual expenses like doctor’s appointments. Neither she nor the Kehoes have disclosed exactly how much that was.

Ms. Baker said she was the one who recommended Dr. Jonathan Ayers of IVF Michigan for fertility services. Dr. Ayers was involved in her two previous surrogate pregnancies.
I worked with Dr. Ayers when he was a Med Student.
