The courts allow modification of certain divorce agreements. Child custody, child support, and spousal support orders can be modified if you can demonstrate that you experienced a substantial change in your circumstances making it difficult to meet the terms of your original agreement.
Examples of valid reasons for a post-divorce modification include: losing a job, relocating, severe illness, substance abuse, and other big changes in your life.
In addition to downward adjustments to child/spousal support and custody payments, you can also request increases as well if you have obtained a higher paying job or a promotion.
