Interest in possession trust
An interest in possession trust is a trust in which at least one beneficiary has the right to receive the income generated by the trust (if trust funds are invested) or the right to enjoy the trust assets for the present time in another way. The beneficiary with the right to enjoy the trust property for the time being is said to have an interest in possession and is colloquially described as an income beneficiary, or the life tenant.
