Where Advocacy Meets Business

Aníbal Martín Sabater “produces high quality work and provides excellent client service” according to sources. He is a firm favourite among many clients who praise his “great adaptability” and “attention to detail.”

–Chambers USA

Aníbal has over 23 years of experience in international commercial and investment arbitration under all major rules.  He is a director of the New York International Arbitration Center, an immediate past member of the Center’s executive committee, and the immediate past chair of the International Law Committee of the Association of the Bar of the City of New York.  Also, in 2019, the firm appointed him to its management group.

Aníbal’s cases typically involve Latin America, conflicting legal cultures, or complex factual and legal situations requiring deep analytical skills.

In 2018, Legal 500 Latin America named him one of 12 leading international arbitration lawyers.  Client- and peer-review-based publications say Aníbal is “‘very responsive and very smart’ [and] has an impressive reputation for his handling of Latin America-based arbitrations, acting for a broad range of clients” (Chambers USA, 2018);  “produces high-quality work and provides excellent client service” (Chambers USA, 2016); and is “very clever and experienced [and] one of the best lawyers around” (Legal 500 USA, 2014).


Licensed in several US jurisdictions, England and Wales (solicitor), and Spain, Aníbal has represented clients in disputes conducted in English or Spanish and governed by the laws of more than 25 nations around the globe.  Those disputes covered a broad range of industries, such as construction, oil and gas, mining and natural resources, power generation and distribution, fishing, food processing, banking and private equity, shipping, sports, project finance, technology, and telecommunications.

In addition to representing clients in pending arbitrations, Aníbal routinely assists companies in evaluating, preserving, and strategizing about their international claims and defenses. He also acts frequently as an arbitrator. Click here for details on Aníbal’s experience as an arbitrator.

Aníbal joined Chaffetz Lindsey in January 2015 and was previously a partner at Norton Rose Fulbright, having spent 11 years with the firm in its Houston and New York offices. Prior to that, Aníbal practiced for six years at Gómez-Acebo & Pombo in Madrid.
