Senior Associate Criminal Lawyer — NS Criminal Lawyers and Associates, working towards the best outcome available in your circumstances.
NS Criminal Lawyers and Associates is a Sydney criminal defence practice led by Muhammad Siddique, a Senior Associate Criminal Lawyer. The firm focuses on two areas and two areas only: criminal law and traffic law. That focus means every matter receives careful, strategic and thorough preparation, with one lawyer accountable for your case from start to finish.

Many people charged with an offence feel overwhelmed by the legal process and unsure of what comes next. Muhammad Siddique provides clear, practical advice in plain language, so you understand the charge against you, the possible outcomes, and the options available to you. Whether the matter is a first-time traffic charge or a serious criminal allegation, the approach is the same: review the evidence carefully, identify the real issues, and prepare a considered strategy for court.
Muhammad Siddique represents clients across Sydney and New South Wales in matters including assault, drug offences, domestic violence and AVOs, bail applications, fraud, sexual offences, firearms and weapons charges, property and public order offences, appeals, drink driving, drug driving, dangerous and negligent driving, speeding and licence matters, and section 14 mental health applications. He appears in NSW Local Courts and works with experienced barristers on more serious matters where required. His work centres on early advice, careful evidence review, clear communication, and strong, well-prepared advocacy before the court. He understands that the outcome of a case can affect a person's liberty, livelihood, family and reputation, and he treats every client's matter with the seriousness it deserves.
Criminal and traffic matters do not always arise during business hours. The firm is available 24/7 for urgent situations, including police questioning and bail. If you have been charged or police want to speak with you, it is important to obtain legal advice before saying anything.
