Due to the historical nature of women often taking care of children, many women did not enter the workforce, however, although this has changed in past 40 years, most men still earn more than most women. And if the ex husband has an ex wife that did not work during the marriage, those are the men that will usually pay the most spousal support.
IN setting spousal support initially, the court will usually employ the dissomaster software program initially--for calculation purposes, however for ongoing spousal support and usually modification thereof, the court will typically then use the 12 factors for setting spousal support under FC 4320. (See below..)
IF you require this type of hearing for ongoing and or modification of spousal support, do not attempt to do this yourself.
IF you are the husband and the ex wife files for such modification, do not do this yourself. An attorney should be used to handle this as there are too many facets to apply in each individual case--and it is best to hire a litigator to do this, NOT an attorney that settles everything [unless you do not care what you get?]
IF you were never married then spousal support does not enter the picture notwithstanding some extraordinary facts (i.e. you believed you were actually married and after 10 years found out you were not, or something close, or fraud was involved,etc. which would open another can of worms!)
