A Martin Order is rare, but essentially does the same thing as a Mesher Order, but it gives one of the parties the right to occupy the former matrimonial home for life or until they get re-married.
They are typically used in cases where the divorced couple has no dependent children or where there's a second property worth less than the family home.
For example, a Martin Order might be used in cases where the transfer of the marital home results in an unfair capital split.
