Alimony refers to funds that one ex-spouse is legally obligated to pay the other following a divorce. It's sometimes referred to as spousal support, but it is very different from child support and should never be treated as the same thing. You can't, for example, cut back on ordered child support because you feel like the alimony you pay is more than enough. In fact, the courts consider alimony and child support completely separately. Whether you are going the traditional route or filing for an online divorce, you should keep them separate too.
