Every transaction is handled by a coordinated team of lawyers, legal staff and specialists. In company acquisition matters we look at structure, contract, tax and liability together.
After closing, many company acquisitions enter the real test of the SPA. A tax assessment, customer complaint or third-party claim may show that a warranty has been breached.
The claim notice then determines whether the buyer validly notifies the claim and whether the seller can react in time. Form, minimum content and delivery route are not mere formalities but often a condition to recovery.
This post shows how warranty claims after closing should be notified and why third-party claims need their own defence rules.
Answer two questions on the concrete finding. You receive an initial assessment of whether documentation is enough or the contract should be sharpened.
Already know you want to get in touch? Go straight to the enquiry form.
The first finding decides whether the issue is only to be documented or must become a claim, indemnity or closing item.
If warranty claims after closing concerns only a side point, a clear note in the due diligence report is often enough. Still, it should be clear which documents were reviewed and why no additional contract mechanism is needed.
If there is doubt, a short legal review is sensible before the point is taken out of the negotiation.
If warranty claims after closing is material and the consequence is clear, the finding can be reflected through warranty, indemnity, condition to closing or purchase price mechanics.
It is important that the data room, SPA and closing list show the same status.
Unclear rules on warranty claims after closing often lead to disputes because buyer and seller later have different expectations on risk, costs and cooperation.
Before signing, the contract should contain clear obligations, periods and consequences.
The claim notice should inform the seller in a way that allows it to review the alleged claim and preserve its rights. Many SPAs therefore require details on the warranty, facts, estimated loss, evidence and affected contracts.
If these details are missing, the seller may argue that the claim was not properly notified. Buyers should therefore not wait until the end of a period but clarify early which minimum information is available.
Third-party claims are not only about the relationship between buyer and seller. A customer, supplier, employee or authority asserts a claim against the target company. The seller often wants a say in defence, settlement or payment.
The SPA should state who informs whom, who conducts the defence, when settlement is allowed and which cooperation duties apply. Without such rules, the external dispute can trigger an additional dispute between buyer and seller.
The relevant documents are the SPA, schedules on the liability regime, the disclosure letter, correspondence on the third-party claim, decisions, lawsuits, invoices and internal loss calculations. Only these documents show whether the claim can be notified coherently and in time.
For sellers the review is mirrored: was the right warranty named, has the loss arisen, was the matter disclosed and were defence rights respected?
The overview separates documentation, contract mechanism and possible consequence.
| Point | Relevance | Contractual response |
|---|---|---|
| Notice period Notice period | Missing a period can cost the claim | Check calendar and delivery route |
| Minimum content Minimum content | Claim must be understandable | Name warranty, facts and loss |
| Third-party claim Third-party claim | External party is involved | Regulate defence and settlement |
| Cooperation Cooperation | Documents are often spread out | Use information duties in the SPA |
The table does not replace a review of the individual case. The contract, data room and economic relevance decide.
Caution: A rushed or incomplete claim notice can weaken the negotiating position. Secure the minimum information and check the delivery route first. Booking an initial consultation (72 euro) can help.
This depends on the SPA. Typically it names the affected warranty, facts, evidence, estimated loss, timing and delivery to the correct recipient.
Yes. Third-party claims also require rules on defence, settlement, information duties and cooperation.
Not blindly. The buyer should secure periods but prepare the minimum content so that the notice is not unnecessarily vulnerable.
