The document basis is not sufficient yet.
Request the documents on the boundary line and do not sign on the basis of an exposé or oral assurance only. The comparison with land register, plans and draft contract shows the real risk.

Checking boundary cadastre and natural boundaries before buying land is a separate review point before signing. It may look like a detail, but it can affect price, use, financing and later disputes.
The key task is to compare documents, land register, actual condition and draft contract. Oral assurances help little if the contract leaves the point open or states it differently.
This post explains which documents on the boundary line matter, which clauses belong in the purchase contract and when renegotiation is advisable.
Quick check
Is this point sufficiently clear before signing?
Answer two questions on documents and contract wording.
Already know you want to get in touch? Go straight to the enquiry form.
Do you already have the key documents on the boundary line?
Without documents, it is hard to assess whether the boundary line is properly handled in the contract.
All paths at a glance
Overview of all answers.
The basis is documented, but the contract must be read carefully.
If documents and contract wording on the boundary line match, the starting point is better. Still check cut-off dates, assurances and effects on escrow, handover and price maturity.
The risk is not sufficiently protected yet.
If the boundary line remains open, the contract should be revised before signing. Depending on the topic, an assurance, condition, retention or more precise description may be needed.
Why this point matters before signing
Why this point matters before signing
Square metres and fence line do not safely show the legal boundary. Differences can affect access, garden, developability and value.
The first step is a concrete document review. Buyers should not rely on labels, but connect the issue to the actual purchase object. This shows whether the boundary line affects value or usability.
This review complements the general contract check. See our focus page on purchase contract review.
Which documents buyers should request
Which documents buyers should request
Request land register extract, cadastre documents, existing survey plans and where needed authority information on developability.
If documents are missing, the contract should at least contain a clear reservation. Otherwise, the buyer carries a risk that could not yet be assessed reliably.
For apartments, management documents may also matter. For land, plans, cadastre and authority documents may be needed.
Review points
What should be visible in the contract
The table shows which points should not only be discussed but documented.
| Point | Document | Contract effect |
|---|---|---|
| Document Evidence or plan | Name as contract basis | |
| Costs Cut-off date and maturity | Allocate in contract | |
| Use Actual and legal status | Assurance or condition | |
| Handover Documentation and open points | Record and retention |
The right clause depends on the specific property and the available documents.
Practical rule: If a point is material for price or use, it belongs in the document review and in the contract before signing. An initial consultation (72 euro) can clarify next steps.
How the contract should protect the risk
How the contract should protect the risk
The contract should clearly include plot number, plan attachment and any assurances on the boundary. If uncertain, a survey reservation may be useful.
Blanket wording such as bought as seen is often not enough for such issues. Specific assurances, conditions, cut-off dates or a precise description are safer.
The clause must fit the escrow settlement. If a risk is clarified only after signing, purchase price maturity should reflect that.
Practical steps before handover and payment
Practical steps before handover and payment
Boundary points, fencing and neighbour use should be documented on site. Open questions should be clarified before price maturity.
Shortly before handover, check whether anything has changed since signing. New documents, resolutions or authority information may affect settlement.
If points remain open, do not improvise. A retention, clarification or amendment is usually better than a later dispute.
