Annulment: What it is and what it isn’t, by Rev. Patrick R. Lagges, J.C.D.
Does an annulment make the children illegitimate?
No. The parents, now divorced, presumably once obtained a civil license and entered upon a legal marriage. Children from that union are, therefore, their legitimate offspring. Legitimate means —legal.— The civil divorce and the Church annulment do not alter this situation. Nor do they change the parents— responsibility toward the children. In fact, during annulment procedures the Church reminds petitioners of their moral obligation to provide for the proper upbringing of their children.
