Statute of Limitations

[Limitations]

As part of my divorce I requested a trust be set up for my son's education. This was varied by the judge and he asked for two lawyers to act as trustees and to be brought back to the judge in April 2000 for the trust to be finalised and the funds would be held in trust until my son became 18 years old where it would then be handed to him. This was never taken back to the judge. My son's father cashed the fund in March 1999 when it matured. Can I still claim for the money to be handed over to my son as he is now 20 years old?
