Brutal cruelty and ill treatment afford lawful grounds for separation, as also does adultery if it has not been condoned. But this separation does not break the bond of marriage. Death alone can do that, and neither is free to marry again whilst the other is still living. For grave reasons a Catholic can obtain ecclesiastical permission to have the separation rendered legal by a civil decree of divorce in order to avoid legal difficulties, but this must be on the understanding that such a decree leaves neither party free to contract another marriage whilst the other party is still living.
