Say you and your spouse/partner separate. There may or may not
be children of the relationship. Prior to your separation either or
both of you worked and your incomes were used to pay the family
expenses. After separation you moved out. Who now pays the expenses
you used to pay for the family?
Often the lower income earning party will expect that his/her
expenses are paid by the higher income earning party, but this is
not always possible as after separation, the reality is that
parties now have 2 households to maintain with the same amount of
income.
Each party should take steps immediately after separation to
ensure that all his or her income is paid into a separate bank
account to which only he or she has access to, and that any redraw
or loan facilities cannot be used by the other party.
