Norwegian contract law and EU contract law have many similarities, but there are also some key differences.

One of the main similarities is that both systems are based on the principle of freedom of contract, which means that parties are free to make agreements and contracts as long as they are not contrary to law or public policy. Both systems also provide for the enforcement of contracts through the courts, and both systems have provisions for the resolution of disputes.

One of the key differences between the two systems is the way in which they regulate consumer contracts. EU contract law has stricter rules in place to protect consumers, including regulations on information disclosure, cooling-off periods, and the right to withdraw from a contract. Norwegian contract law has similar regulations but the level of protection is not as strict as EU regulations.

Another key difference is the way in which the two systems deal with the formation of contracts. EU contract law has stricter rules regarding the formation of contracts, including the requirement of a written form, while Norwegian contract law has a more flexible approach, with more emphasis on the principle of freedom of contract.

Additionally, EU contract law has more detailed regulations on the interpretation of contracts, while Norwegian contract law relies more on general principles and the use of case law.

Furthermore, EU contract law has more detailed regulations on the protection of the weaker party in a contract, such as consumers, while Norwegian contract law relies more on general principles of good faith and fairness.

Overall, while Norwegian contract law and EU contract law have many similarities, there are also some key differences. Norway, as a non-EU member, has more autonomy in shaping its contract laws and regulations, and as a result, there can be variations in the level of protection and rights provided to parties in a contract.
