If you want to create a Terms and Condition Checkbox with the link pointing to the page, you can create it easily. Here is the code which you need to use
[checkbox* terms-condition "I have read and agree to the terms and conditions. *"] <a href="http://www.yoursite.com/terms-and-condition"> Terms & conditions </a>
The code will go in the Contact Form 7 ( like below)

Thats it. If you have any Question feel free to do comments below.
