There is no such list; however, here is my list of pretty dang safe bets that you’ll be paying child support if one or more of these factors are met:
You are the biological or adoptive parent of the child for whom child support is sought and:
You meet all the statutory/regulatory criteria for your jurisdiction to obligate a parent to pay child support.
You have substantially more money than you need on a monthly basis, i.e., a surplus of money that you can obvious spare for the payment of child support.
Or you are found to be able to earn or otherwise obtain more money than you need on a monthly basis, i.e., a surplus of money that you can obvious spare for the payment of child support.
Or you earn (or are deemed able to earn) enough money such that, even if you have to reduce your standard of living slightly or even somewhat significantly to pay child support, you can still live relatively well on less than you currently spend and pay the difference in child support.
About the only sure way to avoid being ordered to pay child support is to prove to the satisfaction of the court that you are unable to earn enough money to support both yourself and the child financially. Even if the other parent has more than enough money to support the child financially and does not even need your money, most jurisdictions will order you to pay child support, if the other parent wants such an order. The child support may be minimal (say, $30 or even less), but you’ll likely be ordered to pay child support, if you aren’t the child’s sole physical custodian.
As with all things divorce and child custody/support related, specific questions need to be answered by either doing your own research regarding the laws and regulations in your jurisdiction or consulting a knowledgeable attorney licensed to practice law in your jurisdiction.
