In such cases

You almost always find this phrase at the start of a sentence. It usually follows a sentence that describes a problem or a condition. For example: "Your phone might get wet. In such cases, turn it off immediately." Notice the comma after the phrase? That’s his best friend. Don't leave him alone! You can also use it in the middle of a long sentence with a semicolon. "The flight might be delayed; in such cases, the airline provides vouchers." It acts as a transition. It bridges the gap between the 'if' and the 'then.' It’s a very logical flow. You can also use it to refer back to a list of scenarios. If you've listed three problems, this phrase covers all of them at once. It’s a great way to save time without losing clarity. Just make sure the 'cases' are actually clear to the reader. If you haven't mentioned a specific situation yet, this phrase will just confuse people. It’s a pointer—it needs something to point at!

It’s very formal or neutral. You wouldn't use it while ordering a burger. "I might want extra cheese; in such cases, please add a slice." That would sound like you're trying to win a debate with the cashier. Use it when you want to sound professional. It’s perfect for a Zoom interview or a polite complaint to a company. It shows you are thinking logically. It gives your words a sense of structure. It’s very common in STEM fields and law. If you use it in a casual text, your friends might ask if you’ve been replaced by an AI. Keep it for the moments when you need to be taken seriously. It’s a power move for your professional English.

In such cases, no refund is given." It’s the backbone of policies. Think about a travel vlog. The creator might say, "Sometimes the mountain pass is closed due to snow. In such cases, we take the long way around." It’s great for explaining plans. In a job interview on Zoom, you might say, "Sometimes projects face unexpected delays.

Use it when the situation is a bit complex. If the 'if' part of your sentence is long, In such cases helps reset the rhythm. Use it when you are writing an essay for a C1 exam. It’s a great way to show the examiner you know how to connect ideas. Use it in a work email when you are explaining a policy. It’s much more professional than saying "If that happens." Use it when you want to avoid repeating the same word. If you've already used "if" three times, this phrase provides a nice variety. It’s also great for summarizing multiple conditions. If you've described three ways a project could fail, this phrase wraps them all up. It’s like a net that catches all the possibilities you just mentioned.

Don't use it for simple, everyday things. "I might be hungry. In such cases, I will eat an apple." This sounds hilariously dramatic. Just say "Then I'll eat an apple." Avoid using it in casual WhatsApp chats with your bestie. It’s too stiff. Also, don't use it if you haven't actually described a 'case' yet. You can't just start a conversation with it. "Hello! In such cases, we should leave." Your friend will be very confused. It’s a reactive phrase. It needs a trigger. Also, avoid using it too much in one paragraph. It can make your writing feel heavy and bureaucratic. Like a strong spice, use it sparingly for the best effect. One well-placed in such cases is worth ten poorly placed ones.

The most common error is forgetting the 's' at the end. ✗ In such case → ✓ In such cases. It’s almost always plural because it implies a type of situation that could happen multiple times. Another mistake is forgetting the comma. ✗ In such cases you should... → ✓ In such cases, you should.... That little pause is important for the reader's brain. Some people also use it when they should use "In that case." If you are talking about one very specific, unique moment, "In that case" is better. In such cases is for general rules or recurring scenarios. Don't mix them up! Finally, don't use it to mean "usually." It doesn't mean something happens often; it means something happens *if* the condition is met.
