A relationship created at the direction of an individual, in which one or more persons hold the individual's property subject to certain duties to use and protect it for the benefit of others.

Individuals may control the distribution of their property during their lives or after their deaths through the use of a trust. There are many types of trusts and many purposes for their creation. A trust may be created for the financial benefit of the person creating the trust, a surviving spouse or minor children, or a charitable purpose. Though a variety of trusts are permitted by law, trust arrangements that are attempts to evade creditors or lawful responsibilities will be declared void by the courts.

The law of trusts is voluminous and often complicated, but generally it is concerned with whether a trust has been created, whether it is a public or private trust, whether it is legal, and whether the trustee has lawfully managed the trust and trust property.
