Domestic justice, by contrast, orders and perfects relations within households. When those who share a household have wills informed by domestic justice, they are disposed by habit to deliver to each what each is due in accord with the role each plays: wife or husband, parent or child, brother or sister, and so on. When this occurs with the consistency of habit, they maintain the shared goods that are the substance of that life, above all their rightly ordered relationships {ST II-II.58.7.3). Finally, there is particular justice, which perfects our various private affairs and relations (5TII- 11.58.7). When present in the will, it enables the just to secure the particular good of those with whom they share some sort of common life, activity, or friendship. Particular justice regards the mutual dealings that go on between persons and the equality that ought to obtain between them {ST II- II.61.1-2), but it also regards the just distribution of those common goods that accrue in their common life (5TII-II.61.1.4).
