“I take the law to be to the following effect. First, a court of equity will order an inquiry and payment of occupation rent, not only in the case where the co-owner in occupation has ousted the other, but in any other case in which it is necessary in order to do equity between the parties that an occupation rent should be paid. The fact that there has not been an ouster or forceful exclusion therefore is far from conclusive. Secondly, where it is a matrimonial home and the marriage has broken down, the party who leaves the property will, in most cases, be regarded as excluded from the family home, so that an occupation rent should be paid by the co-owner who remains. But that is not a rule of law; that is merely a statement of the prima facie conclusion to be drawn from the facts. The true position is that if a tenant in common leaves the property voluntarily, but would be welcome back and would be in a position to enjoy his or her right to occupy, it would normally not be fair or equitable to the remaining tenant in common to charge him or her with an occupation rent which he or she never expected to pay.”
