A deed of trust creates a lien on the purchased property when it is executed and delivered by the trustor/borrower to the beneficiary (usually the lender). Once executed and delivered, the deed of trust takes priority as a security against the property in relation to any other liens previously recorded.
You can search for property records and property ownership information online, in person, or over the phone with a 311 representative. Property owners of all boroughs except Staten Island can visit ACRIS. To search documents for Staten Island property, visit the Richmond County Clerk's website.
While that's a reasonable question, the fact is, trust documents generally avoid the court completely. As such, they are not matters of public record. This means that you likely will not be able to secure a copy of the trust from the Office of the County Clerk or the courthouse in the same way you would a will.
You'll find most California property deeds at the County Clerk's office, also called the Registrar/Recorder office. Some of them provide online searches. Others require visiting their offices. For example, the San Diego County Clerk's Office provides online searches.
Trusts are not filed or registered with the Court. You may wish to contact the County Recorder or the attorney who prepared the trust to obtain copies.
You can find a copy of your previous deed on the Franklin County Recorder's office website. The Recorder's office can also be reached at 614-525-3930.
