You don’t need to have any knowledge of the law to choose the right lawyer for you. Deciding who will represent you as your legal counsel comes down to simple things like whether or not you like them as a person, how dedicated they are to their job, how much time they are willing to spend with you, how helpful and courteous they are, how much experience they have and how well they communicate.
The best way to approach the situation, understand your rights and formulate a winning defence is to speak to a lawyer who has knowledge and experience in the areas that most affect you.
