Often times in many situations such as job or school applications, making a purchase, filling out a survey or form, etc. we are required to check a box confirming that "I agree to the terms and service" or "I agree to the terms" etc.

In these situations many people don't actually read the terms and just check the box, and from my understanding that is expected. This may sound a little ridiculous, but I was wondering if not reading the terms and checking the box anyway would be considered lying in Islam and therefore haraam?

It is an agreement which supposed to be read and understand before you sign.
