Are Catholics who get abortions excommunicated?
Despite the common misinformation prevalent today, the penalty for having an abortion is still excommunication. Canon law states, "A person who procures an abortion incurs an automatic (latae sententiae) excommunication" (CIC 1398). Automatic excommunication for abortion (CIC 1398) applies not only to the woman who has the abortion, but to "all those who commit this crime with knowledge of the penalty attached, and [this] includes those accomplices without whose help the crime would not have been committed" (Evangelium Vitae 62).
However, no one is automatically excommunicated for any offense if, without any fault of his own, he was unaware that he was violating a law (CIC 1323:2) or that a penalty was attached to the law (CIC 1324:1:9). The same applies if one was a minor, had the imperfect use of reason, was forced through grave or relatively grave fear, was forced through serious inconvenience, or in certain other circumstances (CIC 1324).
