Here's a way to do it for free - post them on a blog or website that hosts them...once they are written online, they are timestamped. If someone tried to steal it afterwards and claim it, the time stamp would show that you were the first person to submit it, and it would hold up in court. Alternatively, email them to yourself so you have a date when they were made. If you want, you can go to the copyright commission and pay around $60 (+/-) for a copyright.

Legaly as soon as you write something it's copyrighted. The point would be to prove it. I write my poems on a site called poetrypoem.com and you would have electronic precedence if you needed it they also have links to story sites if you write stories.
