What are the basic legal requirements I have as a website owner? Let's say I run a basic website with no special legal concerns. What legal issues does every website have that I should know about?
Every website needs a terms of service and a privacy policy. A simple Google search will find you plenty of TOS/PP generators. Then, you just a need to place an easy-to-find link to your TOS/PP on all the pages of your website. No matter what kind of site you run, it is also a very good idea to register as an official copyright infringement agent. It costs about $140, but it could save you a LOT of hassle in the future. Other than that, it's hard to say much more since you haven't revealed much about your website. You should be more specific if you want more information.
How come this is viable? Because it’s legal. What if people use their service to commit crimes? What if people use a Ford in a bank holdup? Or a Glock in a murder? Or the US Postal Service in a Nigerian letter scam? If the goods or services are legal and not provided for an obviously illegal purpose, nothing happens.
What are exactly the legal consequences of "All rights reserved"? Almost none. You have to explicitly grant copyright rights. You don't even need the Copyright notice for them to apply. My "almost" is because the notice makes it harder for somebody to argue "they didn't realize". Do I still need an additional SW License Agreement or is the Copyright notice above + a Disclaimer of liability sufficient? If this is free software (I know you said it isn't), do yourself (and everyone else) a favour by picking a license you like. Preferably either GPL or MIT (depending on your taste). There are far too many free licenses already. Please don't add another. (It also makes it much easier for any user of your software: "Oh yeah, GPL v2. We understand that. We can use it." as opposed to "What are the implications of using this one??" As this is not free software, I think you need a paid-for lawyer (who understands IPR in your juridiction.) Edit: In principle, I believe you don't need anything. The code is copyright, so the customer can't do anything with it (without explicit permissions that you haven't granted). However if the customer doesn't realize that or thinks you won't mind, you then have to go to court to enforce your rights (and probably end up with a disgruntled customer). A short, clear, license will make it clear to the customer what they are allowed to do, and save all that aggravation.
There are three questions relevant to this issue: Who owned the copyright in the first place? Was the copyright transferred? If not, was a license given to the site to use the content? In general, under most countries' laws, the person who creates an original work owns the copyright. The person with the copyright has the right to copy and distribute the work, and the right to prevent others from doing so. In some cases, such as where a work is created as a "work for hire" by certain employees under certain circumstances, the initial copyright is held by a third party. You will need a lawyer familiar with your jurisdiction and your circumstances to determine if this is the case. Finally, even if you own the copyright, you can license others to use your content. This may be in an express written document, or it may be an implied license--implied, for instance, by the act of posting it on their blog. The existence and scope of such a license is, again, something that will have to be determined based on your country's specific laws and your specific situation. The bottom line is: if you submitted articles to that blog, you can't complain that they posted them. Depending on the license in effect, you might be able to get them taken down, or you might not. You need a lawyer, not the internet, to tell you what your rights are in this very specific case.
There is no IP in ideas Any code would by subject to copyright (who owns that copyright is itself a convoluted and separate question), however, if the 4 of you abandoned any existing code, notes and images and start over you would have no legal impediment.
What licence should I display in the footer of my website? None unless you want people to copy and reuse the content. The content (except for mere facts) will be protected by copyright regardless. When you expect people to want to copy and reuse it, it makes sense to tell them in advance under what conditions they can do it (instead of being bothered by their questions). This is what displaying a licence is for. If you were a visual designer then a licence would make sense as visuals are likely to be wanted to be copied and used. But a CV, list of projects and comments from customers are probably not likely to be wanted for reuse and distribution, though it is ultimately for you to decide. If you think someone will want to copy and further distribute your content, you'll need to figure out under what conditions you want to allow it, and then search for a licence that fits. If none found, just create your own.
In the UK, the Disability Discrimination Act 1995 includes provisions which are thought to apply to websites, although as far as I know there is no case law on the matter. If a website's use of JavaScript makes it inaccessible to users with some disability, it may fall foul of the DDA. However, there is no law specifically requiring JavaScript-free versions of web pages.
It depends on what information you are sharing, how you got it, and what rights the business asserts over the information. For example, if it is content created by the business and they claim copyright protection you can only use it without their permission in accordance with Fair use exceptions. If you obtain the information through some limited/conditional access agreement you would be subject to the terms of that agreement. As always: If you want a legal opinion specific to your use case you need to consult a lawyer in your jurisdiction.
