Daniel represents individuals and families in complex domestic and international family law disputes, including matters related to divorce, custody, asset division, child and spousal support, paternity, and business valuations. As an experienced litigator and practitioner, Daniel has consistently been recognized in peer-reviewed surveys as a top matrimonial attorney in Toronto and, more recently, Florida. In addition to litigation, he has extensive experience in alternative dispute resolution, including arbitrations and mediations, conducted locally, nationally, and internationally.
Daniel’s cases have attracted national and international media attention and addressed landmark issues and matters of first impression. Notable achievements include securing the return of two Ukrainian children to a non-country of habitual residence, obtaining an unequal distribution award in a long-term marriage—affirmed on appeal, prevailing on an abuse of process claim in a divorce case stemming from the misuse of police to secure exclusive possession of a marital home—also affirmed on appeal, and successfully enforcing an antenuptial agreement leading to the entry of a series of money judgments exceeding $60 Million.
While Daniel does not disclose the names of his clients due to privacy concerns, they are typically high- to ultra-high-net-worth individuals, athletes, or public figures. Daniel is admitted to practice in both Florida and Toronto and has published extensively and lectured on various family law topics.
