Can I file a class action lawsuit against my condo association for gouging with late fees and over charging by an Attorney?

Whether it's an individual claim only, or something that could qualify as a class action, would need more facts to answer. Talk to a MD class action lawyer to review your options. Be well.

You cannot file a class-action lawsuit since you're not an attorney. You can however speak to a Maryland attorney about your options it's doubtful they include a class-action but certainly worth talking about.

The term "class action" refers to a very specific procedural device used to assert a claim on behalf of a large group of people when it is impractical to name all of those people as plaintiffs in a lawsuit. Unless there are a significant number of people in your association affected by this practice (typically 40, but courts are more and more looking for much larger numbers), a class action is probably not appropriate. This does not mean that you don't have a good individual claim - you should talk with an attorney to evaluate your situation. If there are other people affected by this, they can join your lawsuit without it being a class action.
