It's 14 weeks 'no question asked' abortion. For non-medical reason it can be pushed further, as long as 3 third party (2 doctors and a social worker) say 'ok'. Further than that, it's only for medical reasons, again if 2 (or 3?) doctors say you should do it.
I've actually had this discussion two years ago? With a doctor who specialized in finding out genetic defects in the 90s, basically it's very rare to have abortion after the 14th week, and it's only when some developmental issues are found, or when carrying the pregnancy is dangerous (in some cases labor is induced while the pregnant woman under anesthesia, but the fœtus is known to be unviable, those forced labor seems to be the worst situation mentally for patient and sometime medical personnel)
