New York is the professional base of Angus Ni, a trial lawyer and co-founder of Morrow Ni LLP, operating under the Moni Law brand. His practice includes complex commercial litigation for individuals and companies, while his earlier work encompasses international arbitration, securities class actions, and corporate investigations across multiple jurisdictions.
Before co-founding Morrow Ni LLP, Angus Ni practiced at Debevoise & Plimpton LLP and Bernstein Litowitz Berger & Grossman LLP. Those roles included proceedings before international tribunals, securities litigation involving institutional investors, and investigations spanning several jurisdictions.
The current practice includes federal and state court litigation, including matters before the Southern and Eastern Districts of New York. Native-level Mandarin fluency also supports representation of Chinese individuals and businesses involved in transnational disputes conducted within English-speaking legal systems.
The professional record extends across several types of proceedings. Angus Ni has experience involving ICC and ICSID arbitrations, securities class actions in U.S. jurisdictions, and a FINRA arbitration arising from a dispute over a short sale of a public company’s IPO stock.
International Arbitration and Corporate Investigations
Angus Ni’s international arbitration experience includes work completed while he was an associate in the litigation department of Debevoise & Plimpton LLP. His assignments included complex arbitrations before International Chamber of Commerce tribunals and World Bank Investment Treaty, or ICSID, tribunals.
Corporate investigations formed another part of the Debevoise work. He participated in large-scale investigations across several jurisdictions, adding cross-border investigative matters to the international arbitration experience developed at the transnational firm.
At Moni Law, Angus Ni represents Chinese individuals and businesses involved in transnational disputes in English-speaking legal systems. His native-level Mandarin fluency accompanies litigation conducted in English, connecting direct client communication with work in U.S. courts and other dispute settings.
These parts of the professional record involve distinct legal forums. International arbitration and multi-jurisdictional investigations were central to the Debevoise experience, while later roles added securities class actions, commercial litigation, and representation in a FINRA proceeding.
Commercial Litigation From Investor Claims to Arbitration Defense
The securities litigation work of Angus Ni includes his time at Bernstein Litowitz Berger & Grossman LLP. There, he prosecuted numerous securities class actions against U.S. listed corporations on behalf of hedge fund and pension fund investors across multiple industries and jurisdictions.
Those matters involved both domestic and international discovery. At Moni Law, Angus Ni’s securities litigation work also includes advising publicly listed companies on securities litigation risk and related disputes as part of a broader commercial litigation practice.
A FINRA arbitration brought by J.P. Morgan Securities LLC provides a documented example from that practice. Angus Ni, Serena Yang, and Jing He led the Morrow Ni trial team defending a client against fraud and breach of contract claims seeking more than $6.4 million arising from a short sale of a public company’s IPO stock.
After a six-day evidentiary hearing, the FINRA panel denied the fraud claims in full and limited the client’s exposure to $279,250, with each side bearing its own fees. Cross-examination of J.P. Morgan’s own witnesses established that the firm knew the Regulation-SHO compliant close-out cost was $279,250 but left the position open until a historic price spike. The panel held that every dollar above the close-out cost was the direct and foreseeable consequence of J.P. Morgan’s own decisions.
For Angus Ni, the FINRA matter sits alongside earlier institutional investor representation and current advisory work for publicly listed companies. The proceedings involve different clients and different roles, while remaining within a professional history that includes securities litigation and complex commercial disputes.
Angus Ni and Professional Engagement in New York
Angus Ni’s New York legal community involvement includes participation in organizations such as AABANY and the Chinese American Lawyers Forum, known as CALF. This professional engagement accompanies a litigation practice grounded in New York and work before federal courts including the Southern and Eastern Districts of New York.
In September 2026, Angus Ni appeared as a featured panelist at the Legal Careers Panel & Networking Event at NYU School of Law. The event was co-hosted by AABANY, the NYU China Law Students Association, and CALF and brought together senior legal professionals from international law firms, boutique litigation practices, and global financial institutions.
During the event, Angus Ni spoke about career planning, professional development, and the realities of cross-border litigation practice in New York. The appearance was one part of his participation in New York’s Chinese-American legal community.
His trial record also includes pro bono representation in the Zhu Hailong federal criminal matter. Angus Ni secured a judgment of acquittal through trial, adding a documented criminal-defense result to a professional history otherwise centered on commercial litigation, securities disputes, international arbitration, and transnational representation.
New York remains the professional base across these areas of work. The record includes court proceedings in the state, participation in the city’s Chinese-American legal community, and a practice serving clients whose disputes may extend across U.S. and international jurisdictions.
