Who owns the design once it�s finished and paid for this
It would depend on what arrangements were made and what design you are talking about.
Generally, if you were hired to design a logo, for example, the customer owns the logo, because he paid you for it.
If you work for a company and design something in the course of your job, your employer owns it.
Again, there are different circumstances and contracts can make a difference.
