by KHD: what the Greek Electronic Survey Plan Code is
The KHD (Kodikos Ilektronikou Diagrammatos) is the unique code every survey plan receives when it is submitted electronically to the Hellenic Cadastre. Where electronic submission is required for the survey plan accompanying a deed, the notary checks its KHD submission receipt. Here is what it is, where to find it and when you need it.
The most common scene in any Greek notary’s office: the owner finds a buyer, opens the file — and the survey plan dates from the 1990s, with no coordinates and no KHD. Its suitability for the particular deed needs to be checked. Missing required information may delay the sale. Here is exactly what the KHD is, where you find it and when you need it.
Need a survey plan with KHD for a contract? We draw it up and submit it electronically to the Hellenic Cadastre — qualified engineers in Samos, for properties all over Greece. See our survey plan service.
What a survey plan (topographic plan) is
A survey plan is the official drawing of your plot, signed and stamped by a qualified engineer. It records the exact boundaries with EGSA ’87 (GPS) coordinates, the area, neighbouring plots, roads, contour lines, forest cover and every element that affects whether you can build. It is not a sketch — it is a legal document. See our page on survey plans in Samos for details.
What the KHD (Electronic Survey Plan Code) is
The KHD is a unique code assigned to every survey plan after it is submitted electronically to the Hellenic Cadastre. Electronic submission is mandatory for survey plans dated from 16 July 2018 that are attached to registrable deeds. Electronic submission is optional for plans dated before that date; their suitability for the particular deed must be checked separately.
- Assigned automatically on successful electronic submission of the plan by the engineer on the Cadastre platform
- Permanent, as long as the plot’s boundaries or area do not change
- Publicly verifiable — anyone involved can check it
Where to find the KHD of my property
The KHD is printed on the survey plan itself, usually in the legend at the bottom right, together with a verification link or QR code. If you cannot see a KHD on your copy, ask the engineer to check whether an electronic submission receipt exists. The absence of a printed code alone does not establish whether the plan can be used for the particular deed. Alternatively, ask the engineer who drew it up: the code stays registered in their account on the Cadastre platform.
KHD or KAEK? They are not the same
They are constantly confused. The KAEK (National Cadastre Code Number) identifies the property as a land parcel and does not change. The KHD identifies the drawing — the specific survey plan an engineer produced at a specific moment. A parcel has one KAEK, but it can collect several KHD codes over the years, one for each new survey plan.
When it is mandatory
- Selling a property — the notary and engineer check whether a survey plan is required and which plan can be used. Where electronic submission is required, its KHD receipt is supplied.
- Building permit — the e-Adeies platform does not accept an application without an up-to-date survey plan
- Cadastre registration — requires EGSA ’87 coordinates
- Acceptance of inheritance & parental gifts — notaries ask for an up-to-date survey plan
- Legalising unpermitted structures — the first step of every declaration (see legalisation of unpermitted structures)
- Mortgage — banks require it in the valuation file
Is my old survey plan still valid?
The age of a plan alone does not decide whether it can be used. Checks cover whether it shows the property as it is today, EGSA ’87 coordinates where required, and any electronic submission requirement. The engineer and notary or relevant authority identify whether an update or a new plan is needed for the particular use. Better to check it before you put the property on the market, not on the day of the contract. If you are buying, ask for property due diligence in Greece — the survey plan and its KHD are among the first things we check.
And the Electronic Building Identity?
That is a different document. The survey plan concerns the plot; the Electronic Building Identity concerns the building — permits, drawings, EPC and legal status. The engineer and notary check which Electronic Building Identity and compliance documents are required for the particular transfer. When selling a plot with a building, you need both. See in detail what the Electronic Building Identity includes and how it connects with the Hellenic Cadastre. As an in-house engineering team, we handle both under one roof.
📍 Samos specifics: the Cadastre has operated in Samos Town (Δ.Κ. Σαμίων) since 31 August 2017, while other localities were still in the survey and review process in August 2026; procedures and deadlines vary by locality. Many rural plots border forest zones or streams without clear markings. A local surveyor who knows the island saves re-submissions and unpleasant surprises. And before any contract, run a Cadastre check of the property in Samos — area, boundaries, KAEK.

How much does a survey plan with KHD cost?
A standard survey plan with EGSA ’87 coordinates and KHD starts from €350 + VAT. The final price depends on the area, location, terrain and whether a forest-map check is needed.
Can I sell without a survey plan?
It depends on the property and the deed. The notary and engineer check whether a survey plan is required, whether an existing plan can be used, and whether a KHD electronic submission receipt is needed.
What does the TEE have to do with the KHD?
The KHD is not issued by the TEE (Technical Chamber of Greece) but by the Hellenic Cadastre platform. The TEE is involved indirectly: the survey plan is drawn up and submitted by a licensed civil engineer who is a TEE member, and for a building permit it is used on the TEE’s e-Adeies platform. The owner does not need to do anything at the TEE — the engineer handles it.
How quickly is it delivered?
Usually 7–10 working days after the on-site survey. Urgent assignments (3–5 days) at a surcharge.
