I'm Vietnamese, and I'm working inat a Japanese company.

おめでとうございます！

Every day I use Japanese when talking with clients, reporting to my boss and writing email.

羨ましいですよ。

I usually use the sentence form "念のため。。。".

初めて聞きました。教えてくれてありがとうございました。

EFor example :, "念のため、内容を再度確認ください"."

Recently, I sometimeshave been working with European client, ands but I still keep a habit of using sentences like that above.

I translate it to "Just in case, please check again.

I don't know,. Is this sentences in English correct?

はい、そうです。

And iIt may be the normcasual way of speaking or is it not?

I'm not sure what you mean by "normal" so this correction is my best guess.

The sentence can be used in casual or business settings so you're okay.

Do you know any sentences which are the same as the Japanese formone?

Alternatives:

- Just to be certain, please check again. → formal, do not use in a casual setting
- Just to be sure, please check again. → can be used for either casual or business settings

"Just in case, please check again" actually is correct! But you could also say "Please check again, just in case".
