Every woman is entitled to bear upon a lozenge in her own lifetime the arms, quarterings, and difference marks which belonged to her father.
If her husband is an armiger her arms leave the female lozenge and share her husband's shield, ie, are 'impaled' with his arms, his to the dexter (right) and hers to the sinister (left).
