(a) It is the intent of the legislature in this article to provide spousal maintenance primarily as a temporary rehabilitative measure for a divorced spouse whose ability for self-support is lacking or has deteriorated through the passage of time while the spouse was engaged in homemaking activities and whose capital assets are insufficient to provide support.
(b) It is the intent of the legislature in this article that spousal support should be terminated in the shortest reasonable time, not to exceed three years, in which the former spouse is able to be employed or to acquire the necessary skills to become self-supporting. Only in circumstances in which the former spouse cannot become self-supporting by reason of incapacitating physical or mental disability should maintenance be extended beyond this period.
This is exactly the way alimony should work -- a temporary rehabilitative measure to allow the spouse (the wife, in most cases) to get back on her feet -- nothing more. The amount is limited to the lesser of $2500 per month or 20% of the spouse' average monthly gross income per month.
Compare this to New Jersey's evil, twisted, bizarre construct in which a spouse (the man, usually) may be required to pay inordinate amounts of money to his ex forever.
This, of course, is the situation I find myself in. The alimony award to my ex-wife is permanent, and it's a significant fraction of my income -- not only of the income I now earn, but of the income I could ever hope to earn.
It's a horrible situation from my standpoint, but, as with everything else thrust upon me by this divorce, something to which I'll have to adapt.
