About Richter Grewal LLP

Richter Grewal LLP is a criminal and family law firm based in Oshawa, Ontario, with an office on Division Street. The firm was founded by Alan Richter, who was called to the bar in 1999, assisted in the prosecution of a double homicide case for the Perth Crown Attorney's office, then opened a private criminal defence practice in Oshawa in 2012 before later establishing Richter Grewal with Kiran Grewal. Today the firm brings its lawyers, law clerks, and support staff together under one roof, describing a combined background of more than 25 years in professional legal services.

The firm practices in two areas: criminal defence and family law. On the criminal side, its lawyers handle everything from impaired driving and assault charges to drug, firearms, and homicide cases, appearing at every level of court in Ontario, including jury trials and appeals. On the family law side, they draft separation and cohabitation agreements and argue custody, support, and property disputes, and they list out-of-court agreements among their family law services. Richter Grewal serves Durham Region and Northumberland County and says it will also take cases from Toronto, Hamilton, Peterborough, and Lindsay. It offers in-person consultations and keeps a toll free line open for calls from clients who are currently in custody.
