8. If any one carry off a nun from a minster, without the king's or the bishop's leave, let him pay a hundred and twenty
shillings, half to the king, half to the bishop and to the church-hlaford who owns the nun. If she live longer than he who
carried her off, let her not have aught of his property. If she bear a child, let not that have of the property more than the
mother. If any one slay her child, let him pay to the king the maternal kindred's share; to the paternal kindred let their
share be given.
