Many times a non-custodial parent wishes to help his children and agree to pay an amount of support which exceeds the statutory amounts. This is admirable but not advisable in most circumstances. The problem comes when there is a change in circumstances or when it is apparent the obligations cannot be met.
The high obligation may be a bad deal, but the payor can get stuck with it and held in contempt. See: Short v. Short, No. 2011–CT–01096–SCT (2/6/14). All other things being equal, the best policy is to agree to the statutory amount and then make voluntary payments to supplement the lifestyle.
