How to fill in PF witness declaration of union: your options

FoxDocs is one of several ways. Choose the one that suits your case.

  • Official route

    Submission: Attached to the couple’s request to the Polícia Federal. Agency: Brazilian Federal Police (Polícia Federal). It publishes the form and the requirements — check them before you submit. If the agency runs its own online service, it may be the most direct way.

What this document is

«Declaração da testemunha de união estável ou casamento» is a form of the Brazilian Federal Police (Polícia Federal, PF) from its «Declarações e Formulários» section. Under penalty of law, the witness declares that they know the couple, that the couple is not separated in fact or in law, and that they live in a stable union as if married — in a public and lasting relationship since the stated date.

The form is in Portuguese, one page; a printed warning at the bottom cites Article 299 of the Criminal Code (false statements in a document).

Who files it and where

  • the witness — a third person who knows the couple — fills in and signs it;
  • it is attached to the couple’s request to the PF where the union or marriage must be shown;
  • whether you need it depends on your basis: check the document list for it on the PF website.

What the form asks

  • about the witness: full name, date of birth, document (CPF, RNM or RG), nationality, mobile phone, home address;
  • about each of the two partners: full name, date of birth, identity card, RNM or passport, nationality;
  • the date since which the couple has lived together;
  • city, state (UF) and date of signing; the witness signs by hand.

What to bring

  • the declaration signed by the witness;
  • a copy of the witness’s document if the PF list requires it;
  • the couple’s documents used in the request;
  • check the exact list for your basis on the PF website.
