Power of withdrawal is a legal term that describes a persons right to transfer property that is above or excluded by the powers of a trustee but which is limited either by a predefined amount or which is only useable upon the approval of the trustee. Family trusts often use the power of withdrawal clause to prevent children from misusing funds in a trust. In order to access these funds they must go through the trustee; however, the power of withdrawal can stipulate an amount that they can withdraw for their own use prior to reaching the age of maturity set by the trust. Using this statement in the trust allows the creator of the trust some flexibility in how funds are dispersed to the beneficiaries of the trust.
