Key vocabulary for asking someone to sign
Start by learning essential words you will use often.
assinar — to sign
assinatura — signature
documento — document
formulário — form
Use assinar when you request the action, and assinatura when referring to the result on paper. Documento is a general word for anything official, and formulário is for structured papers with fields to fill in.
Polite phrases to ask someone to sign
When you need a polite or formal tone—at work, in a store, or at a bank—these expressions are appropriate.
Por favor, pode assinar aqui?
Por favor, pode assinar aqui embaixo?
O senhor pode assinar aqui?
O senhor, poderia assinar aqui por favor?
A senhora pode assinar aqui?
A senhora poderia assinar aqui por gentileza?
Use por favor and poderia to soften the request. In Brazil, adding por gentileza or se não se importa also sounds courteous.
Usage notes for formal requests
Choose o senhor or a senhora with older people or when you need extra respect. In many workplaces, these pronouns show professionalism. For mid-formal situations, simply use por favor with the verb in the infinitive or the polite conditional.
Casual and informal ways to ask for a signature
Among friends, family, or colleagues you know well, you can use simpler phrases.
Assina aqui?
Pode assinar aqui?
Assina pra mim?
Você pode assinar isso pra mim?
Assina só aqui e pronto
Drop honorifics and add contractions like pra instead of para for a relaxed, natural feel. Remember that tone and context matter: casual phrases may be inappropriate in banks or legal situations.
Asking someone to sign different types of documents
Different documents call for slightly different wording. Here are common scenarios and sample lines.
Contracts and legal forms
Contrato — contract
Por favor, leia o contrato e assine no final
Leia com calma e assine se estiver de acordo
When dealing with a contrato, always invite the person to read. Offer to explain any terms with phrases like se quiser, eu explico os termos or tem alguma dúvida sobre o contrato?
Receipts and delivery documents
Comprovante — receipt
nota — invoice or receipt (informal)
Assine o comprovante, por favor
Assina a nota aqui, por favor
For deliveries, use short, direct lines. Delivery people often say Assine aqui, por favor while pointing to a signature line.
Consent forms and permission slips
Autorização — authorization
termo de autorização — consent form
Preciso da sua assinatura no termo de autorização
Por favor, assine o formulário de autorização
For consent, emphasize clarity and provide brief explanations like é só para autorizar [ação] so the signer understands what they are agreeing to.
Polite ways to ask someone to sign multiple places
When a document needs several signatures or initials, be specific to avoid confusion.
Preciso que o senhor assine nestas três páginas
Assine aqui, aqui e aqui, por favor
Por favor, coloque suas iniciais em cada folha
Pode colocar suas iniciais em cada página onde está indicado?
Use iniciais for initials and point to the exact places. Using fingers or a pen to indicate spots is very common in Brazilian interactions.
What to say if the signer has questions
Be ready to answer simple questions or offer to get help for complicated issues.
Se tiver dúvidas, posso explicar
Você quer que eu explique alguma parte?
Posso chamar alguém para esclarecer
Quer que eu chame o gerente / responsável?
Encourage questions with friendly phrases like não tem problema, pergunte. If you cannot answer, offer to find someone who can.
Common short phrases and gestures to use
Learn these quick lines that are frequently used in real life.
Assine aqui
Por favor
Obrigado / Obrigada
Só assinar aqui
É só uma assinatura
Combine phrases with gestures: point to the line, hand a pen, and maintain a polite tone. Saying obrigado or obrigada after they sign is standard etiquette.
Short dialogues: realistic examples
Reading short dialogues helps you hear how native speakers combine phrases.
Scenario: at a bank
Bom dia, preciso que o senhor assine este formulário.
Claro. Onde eu assino?
Aqui embaixo, por favor. Se tiver dúvida, eu explico.
Perfeito, obrigado.
Scenario: delivery
Assine aqui, por favor.
Posso ver o que é?
É só o comprovante da entrega. É só assinar.
Tudo bem, assino aqui então.
Scenario: at work
Você pode assinar o relatório antes da reunião?
Posso sim, me mostra onde.
Assina na última página e coloca a data.
Feito, entregue-me depois.
Tips to sound natural and polite
Small adjustments make a big difference in how you are perceived.
Use por favor and obrigado / obrigada.
Add pode or poderia for politeness.
Use contractions like pra in casual contexts.
Match formality to the setting: o senhor / a senhora for formal; você for casual.
Point clearly and hand a pen to avoid awkward pauses.
Common mistakes to avoid
Beginners often make predictable errors. Watch out for these.
1) Using the wrong pronoun: avoid using tu unless you are in a region where it is normal.
2) Skipping politeness when the situation requires formality; use por favor and titles.
3) Not specifying where to sign; always indicate the exact spot.
4) Forgetting to ask if they need an explanation for legal documents.
Regional and cultural notes
Brazil is large and linguistic habits vary. In São Paulo and much of southeastern Brazil, você is common in informal speech. In southern and northern regions, you may hear tu used more frequently. The polite forms o senhor and a senhora are widely understood across the country.
Brazilian people often combine verbal requests with physical gestures to direct attention. A friendly tone and a small smile help make the interaction smoother.
