What is Wrongful Birth?

Legal Definition
Wrongful birth is a legal cause of action in some common law countries in which the parents of a congenitally diseased child claim that their doctor failed to properly warn of their risk of conceiving or giving birth to a child with serious genetic or congenital abnormalities. Thus, the plaintiffs claim, the defendant prevented them from making a truly informed decision as to whether or not to have the child. Wrongful birth is a type of medical malpractice tort. It is distinguished from wrongful life, in which the child sues the doctor.
