I'm stuck with one of these, as a trustee, and I strongly recommend you get professional advice as they can be a minefield. The trust will continue for the time specified in the will until the property, the subject of the trust, is ultimately handed over to the beneficiaries. (I assume you are a beneficiary here? Even if you are a beneficiary you may have no legal interest in the trust fund; only the right to be considered favourably by the trustee for an appointment from the trust fund.) The the trustee may have absolute discretion in this area. So, you need to look at the will that set up the trust. Then you can determine if the trustee actually administered the trust as specified in the will. Also, you may need to check to confirm if the trustee paid the discretionary trust tax.
