DTCP and planning authority
Check whether the claimed layout or planning permission appears with the competent planning authority and whether the sanctioned plan covers the exact survey and plot.
Local-body approval
Use the municipal search where applicable and confirm building approval, licence, completion or other status directly with the competent local body.
TNRERA
Search the official project record when RERA applies. Compare promoter, project name, survey numbers, sanctioned plan, registration period and disclosed status.
What these records cannot establish
Planning approval or RERA registration does not prove the seller owns your exact property, that construction matches the plan, that title is dispute-free or that completion is guaranteed.
Site comparison
Have a qualified professional compare the sanctioned layout or building plan with boundaries, road width, setbacks, floors, use and actual construction.
Official verification links
Government URLs and service paths can change. If a deep link fails, start from the named department homepage.
Important limitation
This guide is general information. A specific property still requires independent review by a property advocate, licensed surveyor and the competent government authority.
