I've found some very helpful papers about law and business for designers at AIGA like the AIGA Standard Form of Agreement for Design Services. http://www.aiga.org/content.cfm/design-and-business
Now I'm wondering whether there are any similar resources for (freelance) developers about law issues and general business.
Thanks guys; a couple of links in your answers will help me a lot.
It's essential to use materials which were designed for your local jurisdiction, not least because it won't be obvious how you 'convert' from one jurisdiction to another.
In the UK, it's common for trade associations to act as a portal for such things. In the UK, for example, Intellect (formerly called the CSSA) offers access to agreements as a service to its members. Agreements from trade associations are good because a) they've usually been drafted by a decent lawyer and b) they are, by their nature, a good representation of the norms for the industry. Using them won't undermine your credibility.
There are also lots of organisations who promote materials foocussed on particular issues. Most law firms have articles and materials you can download. The tricky thing is to find one place that brings all the issues together in one place in a coherent way. Also, the freely available materials often seem to have been drafted largely as a means of attracting you to get more advice from whoever created them.
If you just want a general education on pertinent issues, I can highly recommend the Society For Computers & Law in the UK (very cheap membership; lots of materials created by people who know what they are talking about). If you're not trying to get too specific, I think SCL would also be good reading for developers in other jurisdictions.
