Going Pro Se: If you hear "law enforcement" and think "We don't need no stinkin' badges!"...

there might be a problem.

If you deal with a situation on a daily basis, it should be much easier to learn about the law because you don't have to learn the substance of the case at the same time. For example, if you are a contractor and you are sued because of some work that you did, it is a lot easier to pursue the matter if the only thing at issue is whether the work was done correctly. You understand contracting a lot better than most people do, and so you will be in a better position to explain that portion of it. All you have to do is figure out the law and wade along as best you can.

On the other hand, if you're a computer technician and a landlord, and a tenant sues you for some injury they suffered at your property, you're probably not going to know enough about the property to give a good explanation of yourself when you have the added problem of figuring out what you might need to prove in court, what papers you might want to file, and how otherwise to handle the case.

It sounds simple enough, but it bears repeating: if you understand well the area that you're being sued (or suing) in, and you just need to brush up on the law, you might find that to be a lot easier than trying to learn everything at once. You risk becoming overwhelmed.
