Being a former Copyright and Trademark Paralegal, I can confirm for you that once you receive payment for a project, you no longer own the design and do not have any claim of copyright.
A lot of clients will pull random "contract samples" off the internet which are choppy and generalized.
For that reason, they sign my contract, I do not sign theirs. I keep control of the terms so there is no confusion.
On or off UW, as a freelancer, you "work for hire". Don't get me started on Trademarks.

If that's what your contract says. I've just agreed a contract giving me an advance on sales plus royalties AFTER I was paid a flat fee for the original copy.
Although working for hire may be the most common scenario, it isn't a rule.
