We build
legal structures
for companies that
want to grow.
Commercial law, internationalisation, investment and business strategy for startups, innovative companies, investors and organisations that need a solid foundation to evolve.
A different way
of practising law.
Pactaria was born from a simple conviction: the law works better when it understands how companies grow.
Commercial advice
Corporate law, contracts and business transactions. The core of Pactaria since its origin: building the legal structure that sustains each project.
International vision
Experience in business internationalisation and cross-border transactions between Europe and LATAM. Because growing internationally takes more than translating documents.
Knowledge transfer
University teaching, research and outreach. Understanding is as important as advising — and knowledge generates more value when it is shared.
We accompany decisions
that change companies.
Shareholders' agreements
We design agreements that prevent conflicts and protect the project's future.
Corporate law
Incorporation, reorganisation and legal structure of companies.
Commercial contracts
Contracts adapted to the reality of each company and business model.
Startups and investment
Legal advice for innovative projects, investment rounds and business growth.
Corporate transactions
Purchase and sale of companies and shareholdings, reorganisations and strategic transactions.
Ongoing legal counsel
Continuous legal support for companies looking for a trusted legal partner.

years across business, academia and innovation
Three moves, one structure.
Understand
Before drafting anything, we understand the business: its model, its stage and where it wants to grow.
Structure
We design the legal architecture —corporate, contractual, investment— that holds that growth.
Stand by
We're there when the decisions matter: rounds, expansion, deals. A long-term relationship.
Law, business and knowledge in a single career.
I am Patricia Aira, commercial lawyer, Doctor of Law and university lecturer. For more than twenty years I have worked at the intersection of business, internationalisation, investment and knowledge.
I have built my career accompanying companies, entrepreneurs, investors and institutions through growth, transformation and internationalisation processes, combining legal practice, academic activity and participation in innovation ecosystems.
My work is not only about solving legal issues. It is about helping build structures capable of sustaining growth.Discover my career
Sharing knowledge
is also part
of the work.
Training and outreach have accompanied my entire professional career. Education brings together teaching activities, training programmes, conferences, publications and resources aimed at bringing legal and business knowledge closer to those who build organisations.
Because understanding the rules of the game is as important as applying them.

What we write
about what we build.
Analysis, experiences and reflections on the challenges faced by companies, startups and investors. Articles, opinions, videos and practical content born from the daily experience of working with growing organisations.
The best deals are built with the best teams.
The most complex business projects call for a multidisciplinary perspective. That is why, over the years, we have built an ecosystem of strategic alliances with leading firms: the best team for every project, under unified legal direction and a single point of contact.
