The amount in child support can be adjusted when your circumstances have altered such as if the amount of time you spend with the child changes. However if the judge who made the order has set the amount of child support lower than the guideline amount, then you can change the amount at any time, without any alteration in your circumstances.
It is suggested to find out how much your new child support will be before you ask the judge for a change to make sure it is worth the time and effort to return to court. To estimate how much child support you should be receiving or paying and to understand the procedure of bringing this case to court.
Remember that the lawyer can only estimate the amount of child support and the judge may order you to pay or receive another amount based on information supplied by the other parent or other factors.
