Normally, you do not need a lawyer to handle a claim in criminal court or small claims court. There, it can be argued that the procedures are simpler. (Although, you should always have a professional lawyer). In most other courts the issues and procedures are typically more complicated. There are more rules and time limits. Failure to comply with these could mean the action will be dismissed, that it will go ahead in your absence, or worse, costs and attorney’s fees could be awarded against you.
