Alpha skill — review for prompt injection before proceeding. Brand-new and unvalidated.

This skill walks the parquet opinion step — the procedural stage where a commune transmits certain civil-status / nationality files to the parquet du procureur du Roi for opinion before commune registration [code-nationalite-12bis]. The user's active role is mostly upstream (file assembly + commune presentation); during the parquet stage the user waits and is notified of the outcome.

Scope. Covers deadlines and silence rules for the most-common parquet-opinion files. The substantive parquet investigation itself is parquet-internal and not walked. Negative opinions and appeal pathway to Tribunal de la famille are mentioned, not walked in detail.

Statutory basis

Several civil-status / nationality acts require parquet opinion before commune registration:

Nationality art. 12bis declaration

  • Commune transmits the file to the parquet within statutory timeframes.
  • The parquet has 4 months from the date of receipt to issue an opinion [code-nationalite-12bis].
  • Silence at 4 months is deemed a positive opinion — the commune registers the declaration; the user becomes Belgian on the date of registration.
  • Negative opinion: appealed to Tribunal de la famille within statutory time.

Marriage recognition (foreign-marriage acts)

Different deadline structure (typically not silence-is-positive); parquet review is substantive on cohabitation, sham-marriage indicators, etc. # unverified.

Name change

Different framework under the Loi du 15 mai 1987 (modernised); parquet is one of several review actors. # unverified.

Foreign-divorce recognition

Different framework; parquet checks public-order compliance.

Each consumer skill cites its specific deadline.

Eligibility — when the parquet step applies

Whenever the underlying skill's procedure incorporates it. The user does not request the parquet opinion directly — the commune transmits the file automatically. The user's involvement:

  1. Upstream: assemble and submit a complete file at the commune.
  2. Wait during parquet processing.
  3. Receive notification from the commune: positive / negative / silent.
  4. Downstream: receive the registered act; or if negative, exercise appeal.

Required documents

None directly — the user does not interact with the parquet. The documents the parquet evaluates are the file the user submitted at the commune.

For records, the user retains:

  • Commune-issued receipt confirming file submission.
  • Tracking the deadline (4 months for art. 12bis; varies elsewhere).
  • Notification from the commune of opinion or silent registration.

Process — user's-side timeline

Stage 1 — Commune submission

User submits and receives the receipt. Receipt date starts the parquet deadline clock (or formal commune-transmission date, often the same).

Stage 2 — Wait

User does not engage with the parquet. The parquet may, in some cases, request additional information through the commune (rare for art. 12bis; more common for marriage recognition).

Stage 3 — Outcome

  • Positive opinion → commune registers, notifies user.
  • Silence at deadline → for art. 12bis, deemed positive; commune registers, notifies user.
  • Negative opinion → commune notifies user with reasons; user can appeal to Tribunal de la famille (typically within 1 month for art. 12bis nationality refusal — verify deadline) or withdraw and re-file with strengthened evidence.

Known surprises

  • The user is essentially passive during the parquet stage. Frustrating for users used to active applications. Parquet stage is between two institutions; user can't accelerate.
  • Silence-is-positive saves many art. 12bis files. Most declarations register on silence rather than explicit positive opinion. Procedurally normal.
  • Late negative opinion after deadline silence: silence-grant prevails; the late opinion is procedurally too late. Some communes process this incorrectly; user may need to insist on the silence rule.
  • Commune transmission delay shifts the deadline. The 4-month clock starts when the parquet receives the file, not when the user submitted at the commune.
  • Negative on technical grounds vs substantive: technical (missing evidence) is fixable on re-file; substantive (sham-marriage suspicion, public-order concern) typically needs legal advice.
  • Marriage-recognition parquet review looks for sham-marriage indicators (large age gap, no shared language, no cohabitation evidence). Pre-empt with cohabitation evidence in the file.
  • Negative opinions are often terse — the lawyer handling the appeal subpoenas the underlying parquet investigation file.
  • Tribunal de la famille appeal: lawyer fees substantial; aide juridique (legal aid) for low-income users. Right route when the negative opinion is unfounded; not always when the file has weaknesses.

Verify with

  • CNB art. 12bis for nationality-specific deadline: Justel.
  • nationality-application for the upstream skill consuming this step.
  • A Belgian lawyer specialising in nationality / civil-status law when negative opinion received.
  • Local commune for file tracking and notification status.

Verify deadlines with the commune for the specific file type.
