I'm Doug, and I'm sorry to hear of the confusion. My goal is to provide you with excellent service today.
The addition of dependents by you, whether it be a spouse, or child, has no effect on the amount of child support that you pay for your child from another relationship.
Only of you were to later come under a support order
for your step-child who you are adopting---for example because of a divorce
with your step-child's parent---would your child support be able to be lowered for your earlier child.
I understand that you may be disappointed by the Answer you received, as it was not particularly favorable to your situation. Had I been able to provide an Answer which might have given you a successful legal outcome, it would have been my pleasure to do so.
If you have additional questions, you may of course reply back to me and I will be happy to continue to assist you further until your questions have been answered to your satisfaction.
Would you please take a moment to positively rate my service to you based on the understanding of the law I provided by clicking on the rating stars---three stars or more. It is that easy. That is the way I am compensated for having helped you.
Thank you in advance. I wish you the best in your future,
