If you're doing business online, outlining your legal policies -- your terms and conditions -- can be an important step to protecting your business. Attorney Nina Kaufman says there are three major reasons you should consider including them:

1. E-commerce. Consider it as a contract between you and customer, she says. If a dispute arises you'll want to make sure it's handled according to your terms.
2. Blogs. Here's where you can outline what types of content are allowed on your website, such as copyrighted material.
3. E-mail. If you're collecting customer e-mail addresses and other information, explain how you plan to collect and use it.
