No, it isn't. Some couple can negotiate their child support agreement. However, it is challenging and still subject to court approval. This child support agreements are often referred to as "informal agreements" because they occur outside of traditional judicial procedures. They are negotiated between the spouses and submitted to the court for approval. This post will go over the informal agreements and how you might obtain one.
These agreements are complicated because they require both spouses to compromise and agree on a single child support agreement. You must settle all child support issues. It is often difficult for parents to resolve all of these matters without a neutral arbitrator but it does happen.
You can choose to negotiate through lawyers or directly without lawyers. Once the agreement is finalized, it can be included in the divorce decree (but it is still subject to judicial approval) or you can keep it separate.
Once the agreement is final, you must submit it to the court to review. The court will review it to determine that is negotiated fairly between the parties, the support agreement addresses all outstanding issues, and it is in the best interests of the child. The court will always review these matters from what is best for the child.
If you are trying to settle a child support agreement, you may want to speak to a lawyer. There are numerous issues to consider including the frequency of payments, how to calculate payments, when payments should end, and when they should be revised. A lawyer can help ensure that you deal with all issues, so your final agreement is approved by the court.
