A trust is called as Public Trust when it is constituted wholly or mainly for the benefit of Public at large. A public charitable trust is generally floated when there is a property involved, may be immovable (land and building) or movable (investments, business or intangible assets).Different states in India have different Trusts Acts in force, which govern the trusts in the state; in the absence of a Trusts Act in any particular state or territory the general principles of the Indian Trusts Act 1882 are applied.
The main instrument of any public charitable trust is the trust deed, wherein the aims and objects and mode of management (of the trust) should be enshrined. A trust needs a minimum of two trustees; there is no upper limit to the numberof trustees. The Board of Management comprises the trustees.
