[Prospective parents with a mental impairment: is prior competency testing in this group of people who wish to have children justified?]

Doctors can decide to subject individuals who wish to become parents to a test to analyse their parental competence. From a legal perspective there is no justification to subject only those individuals with a mental impairment to such a test. In fact, it could be argued that all potential parents should undergo such a test, but due to the impact this would have on the healthcare system that is simply not feasible.
