Direct answer: a CAR overlap is a cartographic intersection that requires investigation; by itself, it does not prove trespass or loss of ownership. Diagnose the polygon’s origin, the property’s records and the state authority’s message before changing anything.
Use the Agribusiness hub, Property and compliance track, CAR guide, and documents pillar.
| Check | Key question |
|---|---|
| Message | automated alert, formal issue or notice? |
| Geometry | which file and method created it? |
| Title/possession | do the records describe the occupied area? |
| Neighbor | mapping error or real boundary dispute? |
| Databases | are CAR, CCIR and SIGEF consistent? |
Download the receipt, files and notice; preserve prior versions; compare geometries with a qualified professional; and answer through the correct state channel and deadline.
Example: if two polygons intersect because one was traced over an imprecise image, moving a line may be insufficient when the title description is also outdated.
Main risks
- missed response deadline;
- conflict between environmental declaration and title reality;
- delayed financing, licensing or sale;
- wrongly allocated environmental liability;
- inaccurate declaration attributed to the holder.
Does every overlap require rectification?
No. Identify its cause and the authority’s instruction first.
Does SIGEF automatically correct CAR?
No. The systems have different legal functions.
Can I delete the filing and start again?
Not without checking the state procedure and preserving history.
Can an overlap affect a sale?
Yes. It is relevant to buyers, lenders and sometimes the registry office.
When should advisers be involved?
For notices, material areas, neighbor disputes, transactions or title/survey inconsistencies.
