Ask a Lawyer and Get Answers to Your Legal Questions
If there is an immediate threat to you or your family, please call 9-1-1.
If you are being threatened by individuals in person (an imminent threat of physical harm or injury), you can file for a restraining order against that individual (or individuals), see: http://www.courts.ca.gov/1260.htm
If this is an internet matter (you are being threatened online by unknown individuals), you can file a report with the FBI internet crime task force: http://www.ic3.gov/default.aspx
You can find local attorneys using the State and local Bar Association directories, or private directories such as www.AVVO.com; www.FindLaw.com; or www.Martindale.com (I personally find www.AVVO.com to be the most user friendly).
