Decision and process
When written clarification may matter
- Define the intended use and property boundary
- Gather sources, documents and specific questions
- Confirm the applicable procedure with the municipality
What a PIP can clarify
A Prior Information Request is a way to ask the municipality for an assessment of a specific planning operation before moving to a fuller process. The value of its response depends on what was asked, what was submitted and which rules apply to the property.
Read the current RJUE wording, including Article 14, before filing. The process does not remove the need to identify the property, boundary and intended use correctly.
When it is worth asking in writing
If price, deposit or the CPCV depends on building, rehabilitation, a change of use or works, an informal indication should not carry that risk alone. The same applies where there is a constraint, uncertain access or documents that tell different stories.
A PIP is useful when it turns a vague doubt into a question the municipality can assess. “Can I build?” leaves too much open. A specific, located intention gives the response context.
Prepare the question that needs answering
Bring the property identification, the boundary under review, the specific intention, photos and available documents. Where the case is more complex, an appropriately qualified professional can help identify material that may be needed.
Constraints, uncertain access or conflicting information are not reasons to guess an outcome. They are reasons to make the question more precise and identify what still needs confirmation.
Do not treat the process as a promise
Each case has its own facts, documents and competent bodies. This guide does not calculate deadlines, costs, approvals or legal outcomes. Confirm the applicable procedure and material with the municipality and professional advice when the purchase depends on the answer.
Limit of this guide
It helps organise questions and evidence. It is not a licence, municipal decision, certificate, legal opinion or guarantee of outcome. Always confirm the current rules and competent authority for the specific case.
