Cross-border e-commerce involves legal issues regarding the formation and execution of contracts online, applicable laws, and intellectual property. Regulations aim to create a level playing field for fair consumer practices, freedom of movement, and fair competition across the EU. For B2C transactions, regulations require transparency of business details and terms of service, as well as order acknowledgement and correction procedures. IP issues like domain name disputes, passing off, trademarks, copyright infringement are common in e-commerce and can be addressed through litigation or dispute resolution.
