Hey :) it really does depend on what the matter is about.
For matters such as a straightforward (in legal terms) divorce it can be great and the courts can be very encouraging and helpful. For more complex matters it really is advisable to use a trained specialist.
A litigant in person is someone who represents themself in court. It's a bit legalspeak but hopefully it'll give you an idea and some places to go for advice.
