If a beneficiary of a bare trust is over the age of 18 years then they can simply ask the trustees to pay the money out to them that they are entitled to. As long as there is no other criteria to satisfy, the trustees should not refuse. If they do, they may be in breach of trust and a beneficiary could have them removed as trustees. Alternatively, if all beneficiaries are adults and they are in agreement, the trust could simply be wound up.
