In Vitro Fertilization, it is the miracle that many parents prayed for when they were not successful conceiving a child naturally. Generally, IVF does not raise many parental identity issues because it is very clear where the egg comes from, the sperm comes from, and who actually gives birth to the child.
However, when a man is not married to the woman going through IVF and the child is not genetically his, a paternity challenge could arise. Something like this happened in California. Tracey Smith and Gregory Carr were dating, with Carr financing a lavish lifestyle for the two. While they were involved, Carr paid for Smith's IVF treatment, according to Courthouse News Service. Two rounds of IVF did not work, but Carr proposed that the two get married and promised to financially support her for life.
Smith accepted the proposal and underwent a third IVF cycle before Carr abruptly cut off the engagement, according to Courthouse News. Smith claimed in a lawsuit that Carr promised to financially support the child that resulted. Could Carr be responsible for the child?
