Property transactions and due diligence: step by step follows six phases: engagement and confidentiality, data room review, title and encumbrance verification, technical and environmental checks, negotiation of warranties and price adjustment mechanisms, and closing conditioned on what the review found. Each phase has a cut-off point after which walking away turns costly rather than simple.
Who this concerns
The sequence applies whenever a commercial buyer, seller or their counsel is moving a Swedish property or a company holding one from one balance sheet to another. It covers both an asset deal, where the property itself changes hands and title is re-registered, and a share deal, where the buyer acquires the corporate vehicle holding the asset and the property stays registered where it is. The two structures trigger different checks and different exposure, and the choice between them is usually made before due diligence starts rather than as a result of it.
The audience is commercial, not private. A fund acquiring a logistics portfolio, an operator buying the premises it already leases, a lender taking security over the asset, or a developer assembling a site from several parcels all run some version of this process, though the depth of review differs sharply. A single-tenant office building with one owner of record needs less than a mixed-use asset with several encumbrance holders, an active tenant dispute, or a pending planning decision.
Where the seller, the buyer or the entity's parent company sits outside Sweden, the process does not change in structure but it changes in what has to be checked and enforced. A foreign seller means representations and warranties may need to be backed by security, an escrow, or a parent company guarantee, because a post-closing claim against an entity with no assets in Sweden is not worth much on paper. A foreign buyer means the closing mechanics have to account for cross-border payment and, where financing is involved, security that a foreign lender can actually perfect and rely on under Swedish rules. Neither of these is exotic, but both are decided in the transaction documents, not discovered afterwards.

What the law says
Under Swedish law as it currently stands, there is no single statute called "due diligence." What exists instead is a set of rules that make certain facts about a property a matter of public record and certain liabilities attach to ownership regardless of what the buyer knew. Title to real property is recorded through registration with the Land Registry, and that record, together with registered encumbrances such as mortgage certificates, is the starting point for any review rather than the endpoint of it. A clean registration extract does not mean a clean asset: it means the formal chain of title is not in dispute, which is a narrower statement than it sounds.
Environmental liability is the clearest example of a rule that survives the contract. Responsibility for contamination can attach to the current owner of a site independently of who caused it and independently of what the sale and purchase agreement says about allocation of risk between the parties. A well-drafted indemnity reallocates the cost between buyer and seller; it does not remove the buyer's exposure to a regulator, which is a different relationship entirely.
For share deals, the framework shifts toward company law and tax law, because what is being reviewed is not the asset but the vehicle: its liabilities, its tax position, its contracts, and any guarantees it has given that survive a change of ownership. Neither structure is reviewed against a due diligence checklist mandated by statute; the checklist is a professional standard, built around what actually creates risk for the buyer, and it varies with the asset.
How it works in practice
Engagement and confidentiality
The process opens with an engagement letter and, on the buyer side, a non-disclosure agreement covering what the seller is about to disclose. This is also where exclusivity, if any, gets negotiated: a seller granting a period of exclusivity expects a corresponding commitment of resources from the buyer, and a buyer asked to commit to exclusivity should expect to see enough preliminary information to justify it before signing on.
Setting the scope: asset deal or share deal
The structure decision drives everything downstream. An asset deal narrows the review to the property itself, its title, encumbrances, leases, permits and physical condition. A share deal widens it to the target company as a whole: its balance sheet, its tax history, its contracts beyond the property, and any liabilities that do not show up in a title search because they sit inside the corporate wrapper rather than on the land register. Buyers sometimes choose the structure for tax reasons and only then discover the due diligence consequences; the order should run the other way.
The data room and what it should contain
The seller assembles a data room, and its completeness is the single biggest driver of how long the review takes. A complete set typically includes the title registration extract, all registered encumbrances, current and historical lease agreements, service and management contracts, permits and any planning correspondence, environmental reports if they exist, insurance policies, and, for share deals, the target's financial statements, tax filings and any litigation history. Gaps in the data room do not disappear; they get pushed into representations and warranties, which is a more expensive way to close the same gap.
Title and encumbrance verification
This step confirms that the seller can actually convey what the contract says it is conveying. It means checking the registration extract against the entity named as seller, confirming that any mortgage certificates or other encumbrances are either released at closing or expressly assumed, and checking for anything pending at the registry that has not yet been recorded, such as an application still in process. A registration extract is a snapshot, not a guarantee, and the date it was pulled matters.
Environmental and technical review
Where the asset's history or use gives reason to suspect contamination, an environmental survey is standard rather than optional, because liability attaches to ownership rather than to fault. A technical survey covers the physical condition of the building: structural issues, deferred maintenance, and compliance with building permits as actually constructed rather than as originally approved. Discrepancies between the permit file and the building as it stands are common and are usually resolved through a price adjustment or a seller undertaking to remedy, not through walking away.
Cross-border ownership and financing structures
Where financing involves a foreign lender, or where the buying entity sits under a non-Swedish parent, the security package needs separate attention from the property review itself. A mortgage certificate that a Swedish lender can rely on without complication may need additional steps for a foreign lender to perfect and enforce it, and those steps take time that should be built into the closing timetable rather than discovered at the point of drawdown.
Negotiating representations, warranties and price adjustment mechanisms
Everything the review did not fully resolve gets allocated through the contract. Representations state facts as of signing; warranties allocate the risk if those facts turn out to be wrong; price adjustment mechanisms, such as a holdback or an escrow tied to a specific known issue, are used where the parties agree a problem exists but not its final cost. A buyer that relies purely on representations without any security behind them is relying on the seller's continued solvency, which is a weaker position than it looks in the draft.
Conditions precedent and closing
Closing is typically conditioned on matters the buyer cannot control directly: registration of the transfer, release of existing encumbrances, third-party consents where a lease or a loan requires them, and any regulatory clearance the transaction triggers. Each condition should have an owner and a deadline in the transaction timetable; a condition with no deadline tends to become the reason closing slips.
What to check before signing
- That the entity named as seller matches the entity named on the registration extract.
- That every encumbrance on the extract has a defined treatment at closing: release, assumption, or subordination.
- That lease agreements match what tenants are actually paying and occupying, not just what the file says.
- That any environmental report is recent enough to be relied on and covers the actual use of the site.
- That representations are backed by something enforceable if the seller is foreign or thinly capitalised.
- That every condition precedent has a named responsible party and a date.
- That the tax consequences of the chosen structure have been confirmed, not assumed, before signing.
Where a lease dispute or a funding question surfaces mid-process
What happens if the target property is tied up in an active lease dispute?
It becomes a disclosed issue that has to be priced rather than ignored. The buyer's options are to price the risk into the purchase price, require the seller to resolve it before closing, or take an indemnity tied specifically to that dispute. For how this plays out in current Swedish practice, see commercial lease disputes and how the practice has shifted.
Does a foreign parent company change how due diligence is scoped?
It changes what the buyer needs behind the warranties, not the checklist itself. If a warranty claim would ultimately need to be enforced against a foreign entity, the practical value of that warranty depends on how enforceable a judgment or award against it actually is. See recognition and enforcement of a foreign award in an energy contract context for how that question is analysed once a dispute has already crystallised.
Who pays if a title or environmental issue surfaces after signing?
That depends on what the contract allocated and whether the issue was disclosed before signing. Where it was not disclosed and falls within a warranty, the seller typically bears it; where it was known and priced, the allocation follows the contract's mechanism rather than a general rule. On how the cost and funding of that kind of dispute is typically structured, see the budget of a dispute compared across funding options.
The numbers
There is no fixed timetable that applies to every transaction, and stating one would misrepresent how registration and disclosure actually work. Registration of a transfer depends on the current workload at the Land Registry and, more directly, on whether the submitted documents are complete on first submission; incomplete filings are the most common reason a registration that should be routine takes longer than expected. The cost of the review itself scales with the complexity of the asset and the structure chosen: a single-title asset deal with a clean registration history is a narrower exercise than a share deal involving several subsidiaries, historical liabilities and cross-border security.
Price adjustment mechanisms, such as holdbacks or escrow amounts tied to a specific identified risk, are negotiated case by case against the size of the exposure they cover, not against a market standard percentage. Anyone quoting a fixed number for how long registration takes or what a holdback should be, without reference to the specific file, is quoting a convention rather than a legal requirement.
Where it usually goes wrong
The review is only as good as what was disclosed, and a data room with gaps produces a false sense of completeness if those gaps are not flagged and chased. Buyers sometimes treat an incomplete data room as a seller problem to be resolved through warranties later, which shifts risk on paper without reducing it: a warranty is only worth what the counterparty can pay when it is called.
In share deals specifically, liabilities that do not touch the property at all, tax exposure from prior periods, guarantees the target has given to third parties, pending claims, travel with the corporate vehicle and are easy to miss if the review stays focused on the real estate file rather than the target company as a whole.
Portfolio transactions with several sellers, several properties or several linked contracts raise a different problem: a defect discovered in one asset can affect the buyer's position on the whole portfolio if the contracts are cross-conditioned, and disputes arising from that kind of structure tend to involve more than two parties. For how multi-party, multi-contract disputes are actually run compared with a single-counterparty claim, see multi-party, multi-contract proceedings compared with the alternative.
Environmental liability is the recurring blind spot: because it attaches to ownership rather than fault, a buyer that skips a survey on the assumption that the seller caused any contamination and should therefore bear it is making an assumption the regulator does not share. And on financing, foreign lenders assuming their standard security package will simply transpose onto Swedish land without local perfection steps routinely discover the gap at drawdown, which is the worst point in the timetable to discover it.
The review stops being a desk exercise once any of these issues surfaces as a live dispute rather than a disclosed risk to be priced. At that point the question shifts from what to check to what a specific document or a specific clause actually supports, and that is a document-by-document exercise rather than a checklist.
What to do next
The steps above cover what a buyer or seller can run without external input: assembling and reviewing a data room, checking title and encumbrances against the register, and identifying which issues need pricing rather than resolution. Where the review turns up a title defect, an unresolved lease dispute, an environmental question, or a cross-border enforcement gap in the warranty package, the next step is a document-by-document assessment against the specific transaction rather than a general checklist.
