Birth Parent Expenses: Birth parent expenses are not an obligation, but an agency can help coordinate prospective adoptive parents pay, as a matter of charity, actual pregnancy related living expenses, including housing, food, transportation, personal items, clothing, and activities provided to the birth mother prior to delivery. Such payments must be permissible by applicable state adoption laws. The amount paid depends on the needs of the birth parents and will be discussed fully with prospective adoptive parents.
Overall, it's clear that money plays a huge role in adoption. The Donaldson Adoption Institute recently released a presentation highlighting some of the problems with adoption today, including the role of privilege and money. According to this presentation, "more than two-thirds of the adoption community believe privilege and money distort adoption."
