Public-road boundary: acts, plans and parcel evidence

A public-road boundary dossier connects the road’s legal status to the relevant plans and requested act. France’s administrative alignment procedure must not be imported into Switzerland; Geneva uses its own cadastral-plan and boundary framework. Identify the competent authority and compare the current road footprint, parcels and physical references. Separate disputed private rights and building setbacks from the public-boundary question. A neighbouring-land survey is a different task.

Answer

Which road and public status define the request?

France: establish the road’s public status before using administrative alignment under L112-1. Switzerland: identify Geneva road dedication and actual status; a paved appearance does not alone establish the relevant public boundary.

Answer

Which road plans, parcels and physical references must agree?

France: compare road plans, parcels and dated physical markers. Switzerland: retain the same evidence chain for the actual road; a wall or fence does not by itself resolve disputed legal boundaries.

Answer

Who may determine or attest the public boundary?

France: L112-4 supports an owner’s individual-alignment request to the competent road authority. Switzerland: identify the competent Geneva surveying or road process separately; receiving correspondence does not itself prove decision-making power.

Answer

How does the proposed line relate to the current footprint?

France: distinguish the requested boundary and current road occupation. Switzerland: reconcile documented boundary and actual use likewise; the tool records discrepancies rather than turning occupation into a property title.

Identify the competent authority and compare the current road footprint, parcels and physical references. Separate disputed private rights and building setbacks from the public-boundary question. A neighbouring-land survey is a different task.

Answer

Which private rights or disputed facts need a separate procedure?

France: keep private ownership, easements and disputed facts separate from alignment. Switzerland: the road framework also does not automatically resolve every private title dispute; retain the appropriate additional proceeding as an open question.

Answer

What notices, observations and decisions belong in the dossier?

France: connect request, observations and notified decision by date. Switzerland: retain equivalent correspondence and the actual competent act; an explanatory plan sent by a service is not automatically the final boundary determination.

Answer

Why is public delimitation distinct from private surveying and building setbacks?

France: public boundary, private demarcation and building setback concern distinct decisions. Switzerland: preserve those distinctions and the local procedure; one cadastral extract does not establish all construction or ownership rights.
