A trust may either be expressed or implied - that is, created by implication. There are four ways to create a trust. The first is through writing. This must be created and signed by the settler as well as the trustees. The second way is ny oral declaration; the third is through a decedent's will, in which case it is called a testamentary trust. Finally, a trust may be created by a court order. Often, trusts appear in wills, and this does not have to be the will of the wealthy solely. In fact, even a poor person may leave estate plan trusts. Estate plan trusts left to children below 18 will be relegated to a trustee until the child comes of age. This section provides more information about trusts, particularly estate plan trusts.
