Legal issues with trademark?

[DavidKonigsberg]

I have a client with a site "brand"coupon.com if i do real marketing on it and get on the brands radar can the client get in-trouble with the brand legally?

Depending on how it is done, then yes.  The specifics are a bit dependent on where the client is based and where the trademark of the brand is registered. However everywhere has some form of trademark protection and something a passing off law.
