The family acts toward the outside as one person. Who represents it?

The man is its head. He represents the family toward the outside. Above all it is his task to earn the income, to provide for needs and to manage the resources.

Who owns the resources?

All of them together. No member has property of his own. But each has a right to what they hold in common.

Can this lead to conflict?

Yes. The right of each member and the decisions of the head of the family can clash. For the family rests on feeling. Feelings are not always in balance. If the father wastes the resources, for example, this hits everyone.

Summary: The man represents the family and manages its resources. The resources belong to all in common. Since the family rests on feeling, conflicts can arise here.
