(1) In the law of wills and estates, a person appointed by the court to take charge of only a designated portion of an estate during probate. For example, a special administrator with particular expertise on art might be appointed to oversee the probate of a wealthy person's art collection, but not the entire estate. (2) A person appointed to be responsible for a deceased person's property for a limited time or during an emergency, such as a challenge to the will or to the qualifications of the named executor. In such cases, the special administrator's duty is to maintain and preserve the estate, not necessarily to take control of the probate process

The most common method of financing real estate purchases in California (most other states use mortgages). The trust deed transfers the title to the property to a trustee -- often a title company -- who holds it as security for a loan. When the loan is paid off, the title is transferred to the borrower. The trustee will not become involved in the arrangement unless the borrower defaults on the loan. At that point, the trustee can sell the property and pay the lender from the proceeds.

Any trust that imposes limits or controls over the rights of trust beneficiaries. These trusts include (1) special needs trusts designed to assist people who have special physical, emotional or other requirements, (2) spendthrift trusts designed to prevent a beneficiary from wasting the trust principal; and (3) sprinkling trusts that allow the trustee to decide how to distribute trust income or principal among the beneficiaries.
