Law Office of William Conwell

Please Call : 877-378-6513

Welcome to the Law Office of William Conwell...

I am a criminal defense attorney in Lake County, California. I worked previously as a criminal defense attorney in San Francisco, San Mateo, Alameda, Contra Costa, Solano, Napa, Yolo, and Marin Counties.

I have chosen to concentrate my practice on criminal and DUI defense and limit my geographical focus to Lake County and Mendocino County, so the majority of my time is spent working on cases rather than driving hours to distant courts. As a result of this, I am familiar with the Lake County Court's procedures, the D.A.'s, the judges, and the local police.

Furthermore, I do not dabble in civil matters, which allows me to focus all of my energy on criminal and DUI defense. I participate in ongoing legal education regularly, (far more than the California State Bar requires,) and am very familiar with new evolving cutting edge strategies in criminal defense as well as pertinent new cases. I am a member of the California DUI Lawyer's Association, California Public Defender's Association, and the National Association of Criminal Defense Lawyers.

I do not charge for initial consultations in my office and I set appointments on evenings and weekends.

Criminal Defense

I Represent People Charged With:

Domestic Violence: Is a designation of an offense that occurs between 'family or household' members. More specifically, it means that the actors involved in a criminal offense are spouses, former spouses, persons who have a child in common, adult persons related by blood or marriage, adult persons who reside or who have resided together, or persons that have a dating relationship. Domestic violence offenses are common. Domestic violence cuts across all social and economic barriers. If a person is convicted of a domestic violence offense, they must participate in a one year long anger management course, frequently a protective order will be issued to protect the complaining witness, and they lose their right to own or possess a firearm indefinitely. I have had a great deal of success defending clients accused of domestic violence offenses.

Drug Offenses: Drug offenses take many forms: Possession of a Controlled Substance and Transportation of a Controlled Substance. A successful defense of a criminal drug offense is commonly focused upon the constitutionality of the search and seizure by the government. In the case of a marijuana charge, medical marijuana may be a defense if you have been prescribed to use medical marijuana before the criminal action.

Other Crimes: In addition to the previously described offenses, I have defended persons charged with probation violations, felony DUI's, felony injury DUI's, felony theft cases, felony fraud cases, assault cases, and resisting arrest. I have developed an exceptional reputation for defending people accused of criminal misconduct by being tenacious and delivering exceptional results.

Criminal Defense

I limit my practice to criminal defense and DUI defense because I believe it allows me to focus my entire legal practice on one area of the law. I have defended people in criminal defense since June 9, 2003. In Lake County, I have worked as a contract public defender in the Clearlake Superior Court defending people charged with all sorts of misdemeanors since November 2006. I also work as a private criminal defense/DUI defense attorney in Lake County. I go to many criminal defense seminars to ensure that I'm constantly up to date on the law and utilizing the most effective strategies.


The first step I take in defending a person is to interview them and find out their side of the story. The reason I offer free initial consultations is that way the client can form an impression about who their attorney is and what I may be able to accomplish in their case. Additionally, I offer a free initial consultation so that the client can consult with other attorneys and choose the best attorney that meets his/her needs.

After being retained, I review the initial discovery given by the prosecution, frequently police reports. I like to go over the police report with my client to find out if they disagree with the police report. Finally, I request discovery from the prosecution and frequently independently investigate the case either by myself or by having an investigator interview witnesses, and look at the scene where everything took place. This allows me to be prepared to challenge the prosecution's case and advise you of the strengths and the weaknesses of your case. It also allows me to negotiate from a stronger position and gives the prosecution notice that there is no such thing as a simple case.

My philosophy is to look at each case individually and determine what needs to be done, because every case is unique and each of my clients has different needs. I also work hard at maintaining good communications with my clients.


I file pre-trial motions to defend my clients when it is appropriate. A motion is a request for the court to do something. The most common motions are motions to suppress evidence, speedy trial motions, motions to challenge prior convictions, Pitchess motions, motions to compel discovery, motions to dismiss (AKA 995 motions), demurrers, and many more types of motions depending on the case. Sometimes, a successful or even an unsuccessful pre-trial motion means the case gets dismissed or the offer becomes too good to resist.

Citizens are protected from unreasonable searches and seizures conducted by the government by the Fourth Amendment of the United States Constitution and the California Constitution. As a general rule, when a police officer or other government official searches a person who has a reasonable expectation of privacy, the police officer must either have a search warrant, or the police officer must be acting consistently with an applicable exception to the warrant requirement. Absent a search warrant or an applicable exception to the warrant requirement, a search is unconstitutional. The remedy for an unconstitutional search or seizure is exclusion of evidence, which commonly results in the dismissal of the criminal allegation. Needless to say, these are not easy motions to win and success requires a great deal of preparation.

I fight to make sure that the court enforces the constitutional rights of my clients and I have successfully defended people accused of misdemeanor and felony drug offenses by filing and winning suppression motions as well as other charges. If I think the court's ruling is in error; I'm not afraid to appeal the ruling.
