Practical defense for real-world charges

No matter the accusation, every client gets the same level of care and focus. Ian Sinclair defends against:


  • Felony Charges
    Including assault, burglary, drug distribution, and serious violent crimes. Felonies carry long-term consequences—Ian builds proactive, trial-ready defenses to help reduce or dismiss charges.
  • DUI & Traffic Offenses
    Even first-time DUIs can impact your license and criminal record. Ian represents clients facing DUI charges across the Tri-Cities and helps protect driving privileges.
  • Drug Possession & Distribution
    From simple possession to intent to distribute, drug charges require careful review of evidence, search procedures, and alternatives to conviction.
  • Domestic Violence Accusations
    These cases often involve emotional dynamics and no-contact orders. Ian takes a steady, strategic approach to defending clients facing domestic allegations.
  • Theft & Property Crimes
    Shoplifting, burglary, malicious mischief, and other theft-related charges can lead to jail time and lasting record issues. Ian helps clients resolve these cases with minimal long-term impact.
  • Assault & Violent Crimes
    Whether it’s a bar fight or a serious felony assault, Ian provides aggressive defense for clients accused of causing physical harm or threatening violence.
  • Criminal Appeals
    If you believe a mistake was made during your trial or sentencing, Ian can review your case for appealable issues and guide you through the next steps.

Your Future Deserves a Serious Defense

The sooner you speak to an attorney, the more options you may have.
  • What’s the difference between a felony and a misdemeanor in Washington?

    Felonies are more serious crimes that carry longer jail or prison time—often over a year—and can impact your civil rights. Misdemeanors are less severe but still carry real consequences, including jail, fines, and a criminal record.

  • Do I need a lawyer if I’m planning to plead guilty?

    Yes. Even if you intend to plead guilty, a lawyer can help negotiate a better outcome, reduce charges, or avoid certain penalties. You should never plead guilty without legal advice.

  • Can a public defender handle my case?

    Public defenders are qualified attorneys, but they often carry heavy caseloads. Ian focuses on private defense so he can give each client the time and attention their case deserves.

  • How soon should I call a lawyer after an arrest?

    As soon as possible. Early legal advice can help you avoid missteps, preserve evidence, and prepare your defense from the beginning.

  • Will I have to go to trial?

    Not necessarily. Many criminal cases are resolved through negotiation, dismissal, or plea deals. But if trial becomes necessary, Ian is prepared to represent you in court.
