If you and your ex agree not to pay child support, it's important to put that agreement in writing and have it approved by a judge. If you don't do this, the agreement isn't legally binding and either of you could change your mind later.
There are a few reasons why you might want to agree not to pay child support. Maybe you have an informal arrangement where one parent takes on most of the financial responsibility for the child while the other provides emotional support. Or maybe both parents are financially stable and agree that they don't need help from the government to support their child.
Whatever your reason, it's crucial to understand that agreeing not to pay child support can have serious consequences. For one, if either parent later decides they do need or want financial assistance, they won't be able to get it from the other parent or from the government. Additionally, if one parent doesn't hold up their end of the bargain and stops paying entirely, the other parent will likely have a very difficult time getting them to start paying again (unless there's a legal agreement in place).
So if you're considering agreeing not to pay child support, make sure you fully understand all of the implications before making any decisions.
