Spousal support can sometimes make the difference between being able to support yourself after a divorce and struggling to do so. However, some people don't have financial concerns after a divorce, and the likelihood of receiving spousal support is lower.
There are situations in which neither parent is going to have the time to provide care for their child after a divorce.
