Amir Sanjari (defendant) and Alison Sanjari (plaintiff) were married in 1982 and subsequently had two children. In 1999, Alison petitioned the court for dissolution of the marriage. Alison and Amir amicably agreed to joint physical and legal custody. According to the arrangement, each parent would have the children 50 percent of the time every two-week period. Following Alison's petition for divorce, Amir made payments to a private school that he hoped the children would attend. However, the children did not end up attending, and Amir sought reimbursement for those tuition payments. Following a final hearing, Amir was ordered to pay Alison child support in graduated amounts of $175 and $215 weekly. The child-support amounts were to increase as Amir's salary increased. Amir filed an appeal, alleging that the child-support order was erroneous, because it made reference to a deviation from the state child-support guidelines for visitation as opposed to treating him as a joint custodial parent. Amir also alleged that the court erred in refusing to credit him for the anticipatory private-school tuition payments.
