“[T]emporary and permanent spousal support are two different kinds of support. The purpose of permanent spousal support is ‘to provide financial assistance, if appropriate, as determined by the financial circumstances of the parties after their dissolution and the division of their community property.’ [In re Marriage of Schulze; In re Marriage of Burlini.]
In determining spousal support at trial, the court must base the amount and duration of spousal support upon the statutory factors enumerated in FC 4320.
Permanent spousal support may be ordered in a short marriage or a marriage of long duration.
Permanent support is usually a lower amount of money than in temporary orders, and a modification of permanent spousal support requires a change of circumstances. [In re Marriage of Heisterman.]
If an order for spousal support has a termination date set forth in the order, the court may not extend the time unless the court retained jurisdiction in that order.”
