n. an entity created to hold assets for the benefit of certain persons or entities, with a trustee managing the trust (and often holding title on behalf of the trust). Most trusts are founded by the persons (called trustors, settlors and/or donors) who execute a written declaration of trust which establishes the trust and spells out the terms and conditions upon which it will be conducted. The declaration also names the original trustee or trustees, successor trustees or means to choose future trustees. The assets of the trust are usually given to the trust by the creators, although assets may be added by others. During the life of the trust, profits and, sometimes, a portion of the principal (called "corpus") may be distributed to the beneficiaries, and at some time in the future (such as the death of the last trustor or settlor) the remaining assets will be distributed to beneficiaries. A trust may take the place of a will and avoid probate (management of an estate with court supervision) by providing for distribution of all assets originally owned by the trustors or settlors upon their death. There are numerous types of trusts, including "revocable trusts" created to handle the trustors' assets (with the trustor acting as initial trustee), often called a "living trust" or "inter vivos trust" which only becomes irrevocable on the death of the first trustor; "irrevocable trust," which cannot be changed at any time; "charitable remainder unitrust," which provides for eventual guaranteed distribution of the corpus (assets) to charity, thus gaining a substantial tax benefit. There are also court-decreed "constructive" and "resulting" trusts over property held by someone for its owner. A "testamentary trust" can be created by a will to manage assets given to beneficiaries.
