Family

Divorce & Separation

With over three hundred family-related cases, including nullity of marriage, annulment, adoption, custody, and support, we have a deep understanding of both the law and the needs of the client.  Our attorneys work to guide our clients through times of crisis, and we find creative solutions that allow them to move forward in their lives. We understand that these cases are more than legal issues, and we recognize that we are dealing with our clients’ emotional well-being as well.

Business

Business Registration

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 our clients’ concerns are addressed efficiently by a team dedicated to a specific specialist practice area.

Our corporate services include contract and policy review, corporate secretarial and corporate housekeeping services, director services, corporate governance advisory and compliance, regulatory compliance, and industry-specific counseling.

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 Bureau of Investments, the Philippine Economic Zone Authority, the Cagayan Economic Zone Authority and other regulatory agencies.

Employment & Labor

Labor Law

Our services span across several facets of labor law. We represent clients in both employee claims and employer defense.

Our primary objective is to avoid expensive and protracted litigation if possible. To this end, we provide advisory services to employers relative to labor standards, employee termination, contractual and other types of employment, and other concerns affecting the workplace. Our advisory services include the preparation of law-mandated policies and manuals, and employment contracts suited to the needs of the employer’s business.

Our expertise has been shaped by years of experience in labor dispute resolution and labor litigation. Through the Single Entry Approach of the Department of Labor and Employment, we aim for a fair and equitable settlement. Where a peaceful resolution is not possible, we provide representation before the National Labor Relations Commission, the Court of Appeals and the Supreme Court on a wide spectrum of issues, including illegal dismissal, constructive dismissal, unfair labor practices, non-payment of wages, and other cases involving a violation of labor standards.

Lawsuits & Disputes

Litigation

Our litigation services cover a broad range of cases. We represent individuals as well as companies in civil, criminal and commercial disputes before regular courts, special courts and alternative dispute resolution centers in the Philippines.

With strong and steady leadership from our Senior Partners, we offer litigation services relating to family law, criminal cases and investigations, torts and damages, commercial disputes, money claims, medical malpractice, and alternative dispute resolution. We also offer services relevant to wealth perpetuation and settlement of large estates.

Our litigators are not only your lawyers. Our corporate clients appreciate our understanding of the technical and commercial aspects of every dispute we undertake; while our individual clients value the time that we devote and the cost-effective solutions we promote to resolve their concerns.
