Discretionary trust

In the trust law of England, Australia, Canada, and other common law jurisdictions, a discretionary trust is a trust where the beneficiaries and their entitlements to the trust fund are not fixed, but are determined by the criteria set out in the trust instrument by the settlor. It is sometimes referred to as a family trust in Australia or New Zealand. Where the discretionary trust is a testamentary trust, it is common for the settlor (or testator) to leave a letter of wishes for the trustees to guide them as to the settlor's wishes in the exercise of their discretion. Letters of wishes are not legally binding documents.

Discretionary trusts can only arise as express trusts. It is not possible for a constructive trust or a resulting trust to arise as a discretionary trust.
