依據 CA FAMILY.CODE SECTION 3587
原文如下
3587. Notwithstanding any other provision of law, the court has the
authority to approve a stipulated agreement by the parents to pay
for the support of an adult child or for the continuation of child
support after a child attains the age of 18 years and to make a
support order to effectuate the agreement.
所以如果家事庭的法官認為有其需要性,這是他可以引用的法條.
至於其他的問題,基於您所提供的資料的內容過於簡單,同時因為有太多的可能性,老貓無法給予您任何回答.
