Support is a legal obligation in which one spouse makes regular payments to the other spouse, earlier or up to date. Payments are normally issued in cases where one spouse has a higher income than the other. The terms of the agreement depend on the duration of the marriage. Not all payments made under an instrument of divorce or separation are maintenance or separate maintenance. Support or separate alimony does not include: this letter informs the court and other interested parties, such as a mediator or lawyer, that the parties have agreed on an amount of support that one spouse pays to the other. It sets the amount of the maintenance and the schedule according to which it must be paid. The letter must be sent by a spouse after an agreement has been reached and must be part of a court record of separation or divorce. This letter informs the paying spouse that he or she no longer has to pay maintenance for a legal reason that exempts him or her from the obligation. .
