[eluser]The Questioner[/eluser]
I have developed and am selling my own custom-built, ecommerce solution to various clients. My most recent client is asking if they have ownership of the code to their site. I'm not sure where I stand on this. I am based in the UK.
In general terms, the site is based on my own custom platform (which is obviously based on CI), which I use to resell to other clients. The layout and design of the site is customised to this client's requirements.
If it means anything, I do have a copyright notice within the source files that state that the site can only be used by the client for the specific business that the site was originally built for.
I have a contract, but it only refers to payments schedules.
I don't want the client walking away after paying for their site and selling the code/solution on independently. Nor do I want them to produce their own custom versions for any spin-off businesses that they may own in the future.
Does ownership of code and Intellectual Property rights mean the same thing?
