"Guarantee" and "warranty" (Gewährleistung) are often used interchangeably, but legally they are entirely different concepts. Knowing the difference can save you money if your refurbished device breaks down.
What is the Difference Between Guarantee and Warranty?
The **warranty (Gewährleistung)** is a statutory right that applies automatically to every purchase from a commercial seller under German law (§ 437 BGB). You do not need to sign up for it — it is guaranteed by law.
A **guarantee (Garantie)**, on the other hand, is a voluntary service provided by the seller or manufacturer. It exists in addition to your legal rights, not instead of them, and its scope depends solely on the terms defined by the guarantor.
How Long Does the Legal Warranty Last on Used Products?
In general, commercial purchases are covered by a two-year warranty — even for used items. While a seller can reduce this period to one year for used goods, German civil code updates (effective January 1, 2022) impose strict rules for doing so:
- You must be notified of the reduction **explicitly and separately** before finalizing your purchase.
- Simply listing it in the terms and conditions (AGB) is **no longer sufficient**.
- If a valid, separate agreement is missing, the full two-year warranty period applies automatically.
This means: If a merchant only hides the warranty reduction inside their AGB without giving you an active, separate notice, you may still be legally entitled to a full two-year warranty period.
What Does the Shift in Burden of Proof Mean?
During the first year after purchase, the burden of proof is shifted in your favor. If a defect appears, it is legally assumed that it was already present when you bought the item. The seller must prove otherwise. After this first year, the burden shifts back to you, meaning you must prove that the defect was present at the time of purchase.
What Applies When Buying from Private Sellers?
For private sales (e.g., through classifieds/Kleinanzeigen), the legal warranty typically **does not apply** since private sellers are allowed to exclude it completely. An exception occurs in cases of deceit (Arglist): if the seller knowingly conceals a known defect, they remain liable despite the exclusion.
Is There an Update Requirement for Electronics?
Yes, since 2022, products with "digital elements" (such as smartphones or smartwatches) are covered by a legal obligation to provide updates. The seller must provide updates that you can reasonably expect within an appropriate timeframe. Failure to provide updates can legally count as a product defect.
Checklist Before Buying
- Check the warranty reduction: ensure the seller explicitly obtained your consent for a one-year reduction.
- Keep receipts and document any defect that appears within the first year to utilize the burden of proof shift.
- Understand private sale risks: be aware that warranties are usually excluded when buying privately.
- Check update support: verify how long the manufacturer supports the device with security updates.
