A simple trust is a trust under which the trustees hold the trust property for identifiable beneficiaries absolutely, without any active duties beyond preserving the property and transferring income or capital as of right. In practice, the trustees have no dispositive discretion: beneficiaries are absolutely entitled to income as it arises and/or to capital, often on attaining a specified age.In England and Wales and Northern Ireland, “simple trust” is a descriptive term rather than a defined statutory category, broadly aligned with a bare trust where the beneficiary has an immediate and indefeasible equitable interest. In Ireland, the expression is similarly used in practice, particularly in tax and succession planning, to contrast with discretionary or interest‑in‑possession trusts. In Scots law, the closest equivalent is a trust where beneficiaries hold a vested and unconditional beneficial interest and trustees’ functions are largely administrative, although Scots terminology more commonly distinguishes between bare (or nominee) trusts and more complex trusts.Simple trusts are significant for tax treatment, beneficiary rights to call for transfer of trust assets, and the limited protective and management functions available to trustees compared with discretionary or protective trusts.
