Warranty and indemnity claims: cost and likely outcome depend on three variables in every Swedish share deal: how the disclosure letter was drafted, how the limitation and cap clauses in the sale and purchase agreement read, and whether notice was given within the contractual window. Cost tracks the complexity of proving loss, not the size of the claim.
Who this concerns
This concerns a buyer who has found a problem after closing and is deciding whether it is worth pursuing, and a seller who has received a claim letter and is deciding how seriously to take it. It also concerns in-house counsel on either side who has to brief a board on exposure before a decision is made, and a fund manager assessing whether a portfolio company's warranty package still covers a risk that has since materialised.
The pattern is the same across sectors: a representation given in the sale and purchase agreement (SPA) turns out not to match reality, and the buyer wants to recover the difference between the price paid and the value actually delivered. The size of the underlying transaction is less relevant than the structure of the warranty and indemnity clauses agreed at signing. A well-drafted disclosure process on a small deal produces a cleaner, faster claim than a poorly documented one on a large deal.
Readers coming to this from the contracts and transactions practice are usually past the point of general due diligence questions. They already have a specific breach in mind and want to know what it costs to pursue it and how a Swedish court, arbitral tribunal, or opposing counsel is likely to treat it.
What the law says
There is no single statute that governs warranty and indemnity claims as a category. Under Swedish law as it currently stands, a warranty claim is a contractual claim: it lives inside the SPA, and the SPA's own wording on scope, materiality, notice periods, caps, baskets, and de minimis thresholds controls the outcome far more than any default rule of general contract law. General principles of Swedish contract law fill gaps the parties left open, but a well-drafted SPA leaves very few.
An indemnity is treated differently from a warranty even though the two are often bundled in the same clause and pursued together. A warranty breach requires the claimant to show loss flowing from a false representation, which usually means quantifying a counterfactual: what the business would have been worth, or what liability would not have arisen, had the statement been true. An indemnity is a direct promise to pay on the occurrence of a defined event, so causation and loss are largely defined away by the drafting itself. The practical consequence is that indemnity claims are cheaper to run and faster to resolve, because the dispute narrows to whether the triggering event occurred, not to a full loss calculation.
Limitation periods for bringing a claim are set by the SPA in almost every transaction this practice sees, and the contractual period, not any general default, is what a claim notice has to meet. Disputes about timing turn on the wording of the notice clause: what counts as notice, what has to be included in it, and whether a holding notice pending quantification satisfies the requirement.
How it works in practice
The disclosure letter is checked first, before anything else
Before assessing the strength of a claim, the first document reviewed is the disclosure letter, not the warranty schedule. If the matter giving rise to the claim was fairly disclosed against the relevant warranty, the claim likely fails regardless of how the loss is quantified. Sellers who disclosed generally but vaguely, and buyers who accepted broad disclosure without querying it during diligence, both end up arguing about what a reasonable buyer should have understood from the wording used.
Notice is tested against the exact clause, not against fairness
A notice given a week late under a strict contractual deadline is usually fatal to the claim, however strong the underlying facts are. Swedish courts and arbitral tribunals applying Swedish law tend to enforce notice clauses as written rather than reading in a reasonableness exception, because the parties negotiated the clause with professional advice on both sides. The content of the notice matters as much as the timing: a notice that states a breach occurred without specifying the warranty relied on, or without any indication of quantum, is frequently challenged as insufficient.
Materiality thresholds decide whether the claim is even viable
Baskets, de minimis amounts, and caps set in the SPA determine whether a claim is worth bringing at all before any assessment of merits. A technically valid breach that falls below the basket is not a claim, it is a fact for the next negotiation. Aggregation clauses, which allow multiple small breaches to be added together to clear a basket, are frequently the most contested part of the agreement once a claim is prepared.
Quantification is where most of the legal cost sits
The cost of a warranty claim is driven almost entirely by how contested the loss calculation is, not by how contested the breach is. A breach that is admitted but disputed on quantum still requires expert evidence, typically an accountant or valuer, to establish the counterfactual position. Where the claim concerns a warranty about accounts, or about the absence of undisclosed liabilities, the expert work can exceed the legal work in both time and cost.
The interaction between warranty claims and price mechanisms
How the price was structured at signing affects how a warranty claim is framed later. A deal built on completion accounts, as set out in the analysis of share purchase agreement price mechanisms, often produces a purchase price adjustment dispute that runs in parallel with, or instead of, a warranty claim covering the same underlying fact. Parties sometimes discover only after closing that the same issue can be pursued two ways, and the SPA's wording on double recovery then decides which route is actually available.
Cross-border sellers and buyers change the calculus
Where the seller, the buyer, or the target group sits outside Sweden, governing law and jurisdiction clauses become the first question rather than an afterthought. A Swedish court judgment on a warranty claim is only useful if it can be enforced where the paying party holds assets, and enforcement abroad is a separate legal question from the merits of the claim itself. Cross-border groups also raise the possibility that the breach sits inside an intra-group arrangement rather than the target company alone, which is the scenario covered in the material on group restructuring and intra-group transactions. Where that is the case, the warranty claim and the group's internal documentation need to be read together before a figure is put on the claim.
What to check before deciding whether to pursue or defend
- The exact wording of the warranty said to be breached, read against the disclosure letter line by line
- The notice clause: form, content, and deadline, and whether the notice actually sent meets each requirement
- Whether the claim clears the basket and de minimis thresholds, including any aggregation mechanism
- The cap on liability and whether it is a single cap or tiered by warranty category
- Whether the same fact could instead be pursued as a price adjustment under the completion mechanism
- Availability and cost of the expert evidence the quantification will require
- Where the paying party's assets actually sit, if enforcement may need to happen outside Sweden
Frequently asked questions
How much does a warranty or indemnity claim typically cost to bring?
Legal cost is driven by how contested the loss calculation is, not by the headline value of the claim. A claim with an admitted breach and a straightforward loss figure can be resolved on correspondence. A claim requiring expert valuation evidence and cross-examination on quantum costs materially more, regardless of whether the sum in dispute is large or small.
What is the difference between a warranty claim and an indemnity claim?
A warranty claim requires proof that a statement was false and that loss flowed from it, which usually means constructing a counterfactual value. An indemnity is a direct promise to pay on a defined trigger event, so the dispute narrows to whether the event occurred rather than to a full causation and loss analysis, which is why indemnity claims are typically faster and cheaper to resolve.
Can a warranty claim still succeed if the breach was partly disclosed?
It depends on what the disclosure letter actually said and how the warranty is worded. Partial or general disclosure sometimes defeats a claim entirely if a reasonable buyer should have investigated further; in other cases the disclosure is judged too vague to discharge the seller's obligation. The outcome turns on the specific wording used, not on a general rule about partial disclosure.
The numbers
There is no fixed figure that applies across warranty and indemnity claims, because every threshold that matters, basket, de minimis, cap, and notice period, is set by the SPA rather than by any default rule. What can be said with confidence is structural: claims that clear the basket comfortably and rely on a single, well-evidenced breach settle faster than claims that depend on aggregating several smaller items to reach the threshold. Claims requiring an accounting or valuation expert take materially longer than claims where the breach and the loss are both admitted in substance. The contractual limitation period, not any general default period, is the deadline that decides whether the claim can be brought at all, and that period varies from agreement to agreement.
Where it usually goes wrong
The most common failure is treating the notice clause as a formality rather than as the first hurdle the claim has to clear. A notice sent within the deadline but missing required content, such as an estimate of the loss or a specific reference to the warranty relied on, is frequently rejected as ineffective even though it was timely.
The second common failure is pursuing the claim as a warranty claim when the facts actually fit an indemnity, or the reverse. Because the two are pleaded differently and carry different evidential burdens, mischaracterising the claim at the outset produces wasted cost when the pleading has to be reworked later.
The third is underestimating how much the quantification work costs relative to the legal work. Parties frequently budget for legal fees and treat expert evidence as an afterthought, then find that the valuation or accounting work required to prove loss is the larger and slower part of the process.
The fourth, specific to cross-border deals, is assuming that a Swedish judgment or award is automatically enforceable against a paying party whose assets sit in another jurisdiction. Enforcement abroad is a distinct legal step, governed by the rules of the jurisdiction where assets are located, and it should be checked before, not after, a claim is brought.
Where none of these apply, and the breach, notice, and threshold questions are all clear, a warranty or indemnity claim under Swedish law tends to behave predictably: it is resolved on the strength of the disclosure letter and the quantification evidence, not on procedural argument.
What to do next
The analysis above covers what determines cost and outcome in general terms. Where it stops is the point at which someone has to read the actual SPA, the actual disclosure letter, and the actual notice sent, and put a figure on the claim. That review is where an assessment of prospects begins, and it is the point at which this material stops being useful on its own.
Deals structured as an asset purchase rather than a share purchase raise a related but distinct set of warranty questions, covered in the asset deal transfer undertakings process, because the transfer mechanism itself changes what a warranty is actually protecting.
For a specific claim, the practical next step is a document-based review: the warranty wording, the disclosure letter, the notice as sent, and the cap and basket mechanics, assessed together against the facts. Contact the firm to arrange that review.
