An independent single-member law firm dedicated to arbitration, mediation, and civil dispute resolution. We work carefully, one matter at a time.
Arbitralis is an independent single-member law firm organized under the Brazilian legal form of Sociedade Unipessoal de Advocacia, registered with the Federal Revenue Service under CNPJ 53.253.163/0001-42 and headquartered in the interior of São Paulo state.
The firm's practice is deliberately narrow: arbitration, mediation, and civil dispute resolution, with occasional civil advisory work adjacent to those areas. Each matter is handled personally by the firm's principal, from intake through resolution, without delegation to intermediaries or referral networks.
The trade name Arbitralis reflects the firm's orientation: a preference for structured, private, and considered resolution of disputes over adversarial proceedings when the choice is available. The trade name and the domain arbitralis.online are owned and operated exclusively by the firm identified above, with no franchise, joint venture, or licensed partner involved.
A focused practice, centered on resolving disputes efficiently and, when possible, quietly.
Representation and counsel in domestic arbitration proceedings, drafting of arbitration clauses, and pre-arbitration analysis. Work oriented to institutional and ad hoc procedures under Brazilian law.
Structured mediation and facilitated negotiation for civil, commercial, and family matters. Preparation of mediation submissions and post-mediation drafting of agreements and settlement instruments.
Contentious and pre-contentious civil work, including contract disputes, obligations, consumer matters, and civil liability. Court proceedings when negotiation or mediation is not the appropriate path.
Contract review, opinions on obligations and civil liability, and preventive advisory work. Written recommendations delivered in plain language, with defined scope and next steps.
Design of dispute resolution clauses tailored to the transaction: choice of forum, arbitration institution, mediation step-in, applicable law, and procedural safeguards.
Direct settlement negotiation before, during, or after formal proceedings, with realistic assessment of leverage, cost of litigation, and the client's underlying interests.
No referral chain, no junior handling the substance. From intake through resolution, the same person reviews the file, drafts the submissions, and appears in the proceedings.
The practice is intentionally narrow. When a matter falls outside our core areas, we say so at the outset rather than accepting it and adjusting later.
Clients receive short, plain-language notes on the state of the matter and the next steps. Long meetings are replaced by tight written summaries.
When a matter can be resolved through negotiation, mediation, or arbitration, those paths are considered first. Contentious proceedings are pursued when they are the right tool, not automatically.
