Every now and then I do some freelance web development and I was wondering if there is a way to prevent the client from tampering/selling (some parts of) the code? (preferably a free solution)

Thanks in advance.

LE: Sorry for posting this here, I wanted to post it in Business Help. If and admin could move it there (or where it's more suitable) I would be grateful.

Once you hand over the work to them it's their code and they can do whatever they want with it. If the contract says otherwise then they screwed up.

And in case the contract doesn't specify that they can have the code, how can i protect my coding?

With a license. Specified in the contract.

Code obfuscation or "encryption" is not the way to go.
