Guided by years of experience and involvement in diverse foreign and domestic investments and businesses, we provide legal and tax advice for the corporate structure best suited to the client’s needs. Our incorporation and post-incorporation services are customizable for cost-effective results. Apart from procuring permits and licenses from local government units and the Bureau of Internal Revenue, we help clients secure fiscal and non-fiscal incentives from the Board of Investments, the Philippine Economic Zone (PEZA), the Cagayan Economic Zone Authority and other regulatory agencies.

We provide general corporate and retainer services to domestic and foreign enterprises where we bridge the gap between the letter of the law and the demands of doing business in the Philippines. Our diversified and customizable corporate services ensure that the client’s concerns are addressed efficiently by a team dedicated to a specialist practice area.

We give particular attention to associated risks, and any change in circumstances that may affect our clients. We have extensive experience across several areas of commercial activity, including distribution, sales and marketing, logistics, manufacturing, and outsourcing and offshoring, and e-commerce.

Apart from prompt and accurate reporting, we provide clients with advice on approaches to common and complex securities compliance issues. We arm our clients with their own compliance policies which we review and update on a regular basis. Our services also include compliance with the listing standards and disclosure rules of the Philippine Stock Exchange.

Our litigation services cover a broad range of cases.  We represent individuals and corporations in civil, criminal, and commercial disputes before regular courts, special courts and alternative dispute resolution centers in the Philippines.  Our corporate clients appreciate our understanding of the technical and commercial aspects of every dispute, while our individual clients value the time that we devote and the cost-effective solutions we utilize to resolve their concerns.

Our crisis management team provides legal advice to clients wherever they face a critical issue calling for an emergency response.
