A pet trust is a legal arrangement to provide care for a pet after its owner dies. Responsible pet owners always want to ensure that the needs of their animal companions are met and, while we may not like to think about a time when we cannot provide proper care for our beloved dogs and cats, responsible pet owners also need to think about providing for pets in their estate plans. In 1991, California enacted a law which authorizes Pet Trusts in California. These Pet Trust provisions can be included in your will or trust agreement. Existing estate planning documents can also be amended to add these provisions.
