§ 10. Additional time limit when you did not know about the claim

§ 10 is a safety rule. It helps when you did not manage to enforce your claim in time because you lacked important knowledge. It can also help when something outside your control made it impossible to interrupt limitation.

The most important words are "necessary knowledge". You do not get an additional time limit just because you did not have a full overview. You must have lacked knowledge that was actually necessary to demand the money. It may be that you did not know the claim existed. It may also be that you did not know who owed the money.

At the same time, the law requires you to pay attention. The period does not only start when you actually obtained knowledge. It also starts when you should have obtained knowledge. This means you can lose if you fail to look into obvious leads. You cannot close your eyes and say you did not know.

The first paragraph gives you at least 1 year from when you obtained or should have obtained necessary knowledge. This is not a new ordinary 3-year period. It is an additional time limit. If the ordinary period has already run out or almost run out, you get one last chance to act. You must use it actively.

The second paragraph concerns obstacles. If limitation cannot be interrupted because of law or another insurmountable obstacle, you get at least 1 year after the obstacle ceased. An insurmountable obstacle is something more than the matter being difficult, unpleasant or time-consuming. It must be an obstacle you could not get around, and that is not due to your own circumstances.

The third paragraph concerns a more special situation: the debtor has left the country after the claim arose. If you can only interrupt limitation by steps abroad under § 23, you get at least 1 year from when you obtained or should have obtained knowledge that the debtor once again has ordinary jurisdiction in Norway, or that limitation can be interrupted in another way. Jurisdiction means where the case can be brought. In plain language: where you can sue or pursue the claim.

The fourth paragraph sets limits. § 10 cannot extend the limitation period by more than 10 years in total. And it cannot extend the 20-year limit in § 9 no. 2 for compensation. This means that § 10 helps, but it does not make claims last forever.

What does "I did not know about the claim" mean?

It means you lacked knowledge that made it possible to understand that you had a claim. Perhaps you paid a bill twice without noticing. Perhaps someone concealed a fault. Perhaps you only later found documents showing that someone owed you money. Perhaps you knew something was wrong, but not that you had a monetary claim (pengekrav).

But it is not enough to say "I didn't think about it". You must have lacked necessary knowledge. If the information was right in front of you, and you should have looked into it, the period may be counted from the time you should have understood the situation.

A typical example is a mistaken payment. If you pay the same invoice (faktura) twice, you have a claim for repayment. If you only discover the mistake after 4 years, § 10 may become relevant. But if the bank statements clearly showed the double payment, and you had every reason to check them, the other party can argue that you should have discovered it earlier.

Another example is when the debtor's identity is hidden. You know you have suffered a loss, but you do not know who is behind it. In that case, the period under § 10 can only run from when you obtained or should have obtained knowledge about the debtor.

The point is that § 10 does not reward passivity. It protects you when you genuinely lacked necessary knowledge, even though you acted reasonably.

How much extra time do you get?

You do not automatically get 10 extra years. That is a common misunderstanding. The first paragraph says that limitation occurs no earlier than 1 year after you obtained or should have obtained necessary knowledge. This means you must have at least 1 year from the time of knowledge.

If the ordinary limitation period (foreldelsesfrist) still gives you more than 1 year, you do not really need § 10. Then you follow the ordinary period. § 10 is important when the ordinary period has already run out, or runs out so quickly that you would otherwise not get reasonable time.

The fourth paragraph says that the extension under § 10 cannot be more than a total of 10 years. This means the law sets an outer limit. Claims should not be able to live on indefinitely just because someone says they did not know.

With compensation claims, you must be extra careful. § 10 cannot extend the time limits in § 9 no. 2. That is the outer 20-year limit for compensation. If that limit applies, § 10 cannot be used to get around it. The exceptions for personal injury (personskade) are found in § 9 itself, not in § 10.

What is an insurmountable obstacle?

An insurmountable obstacle is something that actually prevents you from interrupting limitation. It may be a statutory rule, a war situation, serious conditions in another country or other extreme obstacles. It must be something that is not due to you yourself.

It is not enough that you were short of money. It is not enough that you were unsure. It is not enough that you did not have time to call someone. Nor is it enough that it was cumbersome. The law uses strong words. The obstacle must be insurmountable.

This means the second paragraph is applied more narrowly than many people think. It is not a general "it was difficult" rule. It is an emergency rule for cases where it was actually not possible to interrupt limitation.

Even so, the rule can be important in international cases. If a debtor is abroad, and for practical or legal reasons you cannot use ordinary Norwegian steps, § 10 third paragraph may become relevant. But even then you must pay attention. The period starts when you obtained or should have obtained knowledge that you could act again.

What happens if you get it wrong?

If you misunderstand § 10, you can lose your claim. The most common mistake is to believe that the provision gives you plenty of time. It often does the opposite. Once you obtain necessary knowledge, you have at least 1 year. That year can pass quickly.

Another mistake is to put off looking into things. If you should have obtained knowledge earlier, the court may find that the additional time limit started earlier. Then it does not help that you actually only read the documents later.

If you rely on an obstacle, you must be able to explain the obstacle specifically. What stopped you? Why could it not be overcome? Why was it not due to your own circumstances? When did it cease? Without such answers, the rule becomes difficult to use.

When you discover an old claim, write down the date you discovered it. Also write down what you discovered, and how. Save the documents that show this. Then send the claim in writing as quickly as possible.

If you do not know who the debtor is, you must actively look into it. Send questions. Ask for documentation. Check agreements, bank statements, messages and registers where it makes sense. Do not wait.

If the period may have run out, you must consider interruption of the limitation period (fristavbrudd). This can be acknowledgement of the claim (erkjennelse) under § 14 or legal action (rettslige skritt) under § 15. Do not rely on § 10 alone to save you.
