A 'trust agreement' refers to a legal document that defines the terms and conditions of a trust, including the duties of the trustee and the rights of the beneficiaries. This document is vital in establishing a trust, so it is clear what assets will be included, who the beneficiaries are, and how trust assets will be managed. Synonyms for 'trust agreement' include confidence agreement, fiduciary agreement, trust deed, and legal document. While these variations may have subtle differences in meaning, they all refer to a legally binding agreement that sets out the terms and conditions for managing trusts. These agreements are important as they help to create a sense of trust and confidence between the parties involved, which can lead to more successful and beneficial relationships.
