Practice Areas
At Herrera Arellano LLP, we bring together experienced litigators, former federal prosecutors, and trusted advisors to guide clients through complex legal, regulatory, and public-policy challenges. Our team offers seasoned judgment and strategic insight across a wide range of practice areas.

Litigation
Our litigators have tried and argued dozens of cases and appeals across the state and federal courts. In addition to frequently litigating election matters of public significance, we litigate complex cases involving contracts, securities, class actions, real estate and land use, defamation and the First Amendment, and administrative and public law.

Investigations, White Collar & Government Enforcement Defense
Our attorneys include alumni of the U.S. Department of Justice and lawyers who practiced in the white collar department of an Am Law 100 law firm. We represent clients in criminal investigations and enforcement actions brought by the government, frequently leveraging our experience in election and public law in matters involving campaign finance and public integrity.

Public and Administrative law
We regularly advise public and private entities and individuals concerning public and administrative law matters, including the First Amendment, public records and open meeting laws, procurement, lobbying and government ethics, licensing, land use, tax, and regulatory affairs.

Political Law
Our attorneys are deeply experienced and prominently recognized in campaign finance and election law. We regularly advise candidates, political committees, corporations, nonprofit organizations, labor unions, public entities, and donors on all aspects of federal and state campaign finance law, including defense against enforcement actions brought by regulators or other government entities. We also advise and litigate matters involving voting rights, redistricting, ballot initiatives and referenda, candidate nominating petitions, recounts, and the conduct and administration of elections.

Nonprofit Law
We advise concerning the formation, governance, and operation of nonprofit organizations and related compliance issues, including adherence to federal tax laws governing 501(c) organizations.

Government Relations
Our firm offers a range of legal and lobbying services to organizations and businesses with interests in Arizona and Washington DC, including representing clients in regulatory matters, advising clients on policy and political strategy, and directly lobbying federal and state officials.
