Both alimony and child support can be changed after a divorce if the party seeking the change can show a change of circumstances that warrants a change in the support amount. Generally, the changed circumstances must be significant and long-lasting. For example, the loss of a job or a health issue, for a short time, may not be sufficient to constitute a changed circumstance. On the other hand, a significant and debilitating illness or change in employment status can be the basis for either an increase or decrease in the support amount.
