This is a great video on the basics of creating a Trust. As the video indicates, there are a number of reasons an individual or married couple may create a Trust. In California, a Revocable Trust can help avoid Conservatorship and Probate.
This video is targeted toward more affluent clients, but the basic principles are the same. There are generally 3 parties involved in creating and managing the Trust: Settlor (aka Trustor or Grantor), Trustee, and Beneficiary. The Settlor creates the Trust. The Trustee manages the Trust assets. The Beneficiary receives the benefits of the Trust assets.
