(1)In determining the amount of aliment to award in an action for aliment, the court shall, subject to subsection (3) below, have regard—
(a)to the needs and resources of the parties;
(b)to the earning capacities of the parties ;
(c)generally to all the circumstances of the case.
(2)Where two or more parties owe an obligation of aliment to another person, there shall be no order of liability, but the court, in deciding how much, if any, aliment to award against any of those persons, shall have regard, among the other circumstances of the case, to the obligation of aliment owed by any other person.
(3)In having regard under subsection (1)(c) above generally to all the circumstances of the case, the court—
(a)may, if it thinks fit, take account of any support, financial or otherwise, given by the defender to any person whom he maintains as a dependant in his household, whether or not the defender owes an obligation of aliment to that person; and
(b)shall not take account of any conduct of a party unless it would be manifestly inequitable to leave it out of account.
