Portuguese Legal & Admin Language: The Bureaucratic Register

• Synthetic Passive (voz passiva sintética): This is formed with a verb in the third person and the clitic pronoun se. It's used for general rules or actions where the agent is irrelevant. For example, Solicita-se o preenchimento do formulário ("The completion of the form is requested"). Note that the verb agrees with the subject: Alugam-se apartamentos ("Apartments are for rent").

• Analytic Passive (voz passiva analítica): This is the familiar ser + past participle construction. It's often used when the agent is specified. Compare the active O fiscal emitiu a notificação ("The agent issued the notice") with the passive A notificação foi emitida pelo fiscal ("The notice was issued by the agent"). This structure elevates the official action (a notificação) above the individual agent.

• The Formula: Infinitive Stem + Clitic Pronoun + Future/Conditional Ending
• Example: To say "The contract will be signed," you take the infinitive assinar, add the pronoun se, and append the future ending -á. The result is Assinar-se-á o contrato.

• Function: It establishes the conditions under which the main clause of the sentence will apply. Se o inquilino não pagar a renda, o contrato será rescindido ("If the tenant does not pay the rent, the contract will be terminated"). The action não pagar is a future possibility that triggers a legal consequence.

• Formation: For most verbs, it's derived from the third-person plural of the preterite (eles/elas pagaram), by dropping the -am ending. Thus, pagaram becomes pagar. Irregular verbs are a major challenge and are covered in the "Common Mistakes" section. For example, viram becomes vir (Se ele vir...) and vieram becomes vier (Quando ele vier...).

• Instead of: O requerente deve pagar a taxa. ("The applicant must pay the fee.")
• It becomes: É da responsabilidade do requerente proceder ao pagamento da taxa. ("It is the applicant's responsibility to proceed with the payment of the fee.")

No. Your priority is 100% receptive. You must recognize informar-se-á means "it will be informed." For your own formal writing, using the analytic future passive (o requerente será informado) is perfectly acceptable, formal, and much safer. Attempting and failing at mesoclisis looks worse than avoiding it.

In core legal and state functions, no. It is deeply entrenched in the judicial system and formal state administration. However, there are public-facing simplification efforts (like Portugal's Simplex program). Government websites and general public notices are slowly moving toward a linguagem clara (plain language), but the underlying legal documents remain complex. In Brazil, mesoclisis is seen as far more archaic than in Portugal and is rarer even in formal writing, but the rest of the bureaucratic structure remains.

Look for the trifecta: 1) Complete absence of personal pronouns like eu/você. 2) Conditional clauses using the Future Subjunctive (se for, quando tiver). 3) An abundance of abstract nouns ending in -ção, -mento, and -dade (obrigação, procedimento, responsabilidade).

Standard dictionaries are often insufficient. Use specialized resources. For European Portuguese, the legal dictionary at Infopédia is excellent. For Brazilian Portuguese, the Senate's Vocabulário Jurídico is a good resource. Never rely on direct machine translation for a single legal term; context is everything.
