索赔

In a sentence, you usually say 向 [person/company] 索赔. This means 'to claim compensation from someone.' You can also say 提出索赔 which means 'to file a claim.' It sounds a bit serious. Don't use it if a friend accidentally drops your pen. Use it when there's a receipt involved or a contract.

Use it at the airport if they lose your luggage. Use it after a car accident when talking to insurance. It’s perfect for a restaurant if you find a literal shoe in your soup. It works best in professional or consumer situations. It shows you know your rights and you aren't playing around.

Avoid this if your friend is five minutes late for coffee. Don't use it for emotional favors or small social mistakes. If you use it with family, it sounds like you're suing them. It’s too heavy for a casual apology. Stick to 赔偿 for general 'making it up to someone.'

In China, the concept of 'rights protection' or 维权 has exploded recently. People are much more likely to 索赔 now than twenty years ago. There is a famous 'Consumer Rights Day' on March 15th. On this day, everyone talks about their 索赔 stories. It’s a sign of a modern, law-conscious society.

理赔 is what the insurance company does (processing the claim). 赔偿 is the general noun for the money itself. If you want to be more aggressive, you might hear 要求赔偿. But 索赔 remains the standard, punchy term for the act of claiming.
