FAQ
1. What services do public law firms in the Distrito Federal typically offer?
Most public law firms in Brasília can help you with both legal advice and court representation. Advisory work includes helping with bidding and government contracts (licitações), following the rules, concessions and public-private partnerships and issues related to administrative law. Litigation services include defending against actions for administrative improbity (improbidade administrativa), constitutional challenges, representation in the Federal Court of Accounts (TCU) and appeals to the Superior Courts (STF, STJ). In addition to their regular work, many companies also do regulatory work for certain industries, like energy, telecommunications, infrastructure and other fields that are regulated.
2. How much do public law services usually cost in Brazil?
Prices can be very different depending on how complicated the case is, how big and well-known the firm is and what services are needed. Bigger full-service companies like BFBM usually charge by the hour based on their size and the experience of their partners. Specialized boutiques may offer different ways to pay, such as monthly retainers for advisory work or contingency structures for certain types of litigation. During the first meeting, it is a good idea to ask for detailed fee proposals and talk about how billing works.
3. How do I know if a public law firm in Brasília is reliable?
Some important signs that a company is trustworthy are (1) being listed in well-known legal rankings like Leaders League, Legal 500, Análise Advocacia and Best Lawyers; (2) the firm’s history and how long it has been in business; (3) client reviews and case studies; (4) partners’ past work in public administration, regulatory agencies, or the judiciary; (5) being a member in good standing of the Brazilian Bar Association (OAB); and (6) being open about methods and results. Getting references from clients in the same field as you makes you feel better.
4. Are public law firms in the Distrito Federal suitable for small businesses?
Yes, many public law firms in Brasília help small and medium-sized businesses (SMEs), especially those that deal with the government or work in industries that are heavily regulated. Big companies may focus on business clients, but small businesses may find that niche boutiques have more flexible prices and better customer service. You should talk about your needs and budget up front so you can find a company that can meet them and stay within your budget.
5. What should I prepare before contacting a public law firm in Brazil?
Before you call a public law firm, make sure you have: (1) a clear description of your legal issue or goal; (2) any relevant documents, contracts, or court filings; (3) information about the government agencies, courts, or regulatory bodies involved; (4) your timeline and any deadlines; (5) your budget limits; and (6) questions about the firm’s experience with cases or sectors like yours. If the company is well-prepared, they can give more accurate initial assessments.
6. How long does it usually take to see results from public law services?
Depending on the situation, timelines can be very different. Getting advice like contract reviews or regulatory opinions can take days or even weeks. Litigation, particularly in the superior courts (STF, STJ) or the TCU, may require months or even years to resolve due to intricate regulations and a substantial caseload. Your lawyer should be able to give you a good idea of how long things will take based on the case and the court.
