To my knowledge you are only required to pay CS for your child UNTIL they attain their 1st university/college degree and your obligation should be fulfilled, for at this point, the child should be able to find work suitable in their area of schooling to maintain themselves and afford the cost of a 2nd degree. UNLESS your income is extremely high, 150,000 and over, then 'perhaps' you may be required to contribute. If your income is average, 40G, 50G, 60G, then your obligation is complete after their 1st degree. Get another opinion from a 'reputable' lawyer.
