Your attorney went to law school and probably has years of experience in this field. You don’t. That means that he/she will know things that you don’t about the legal process. If you instruct your attorney not to take certain steps, either to save money or because you want to stay in control, the outcome in the parts of the case you do yourself will be your responsibility, even with an attorney coaching you. There may be hidden snags in your case that you aren’t aware of because you don’t have legal training. That is why you must be careful to discuss your legal matter thoroughly with your attorney.
Be sure you are at ease handling the parts of your case that you take on. Make sure that you aren’t taking on anything which is too technical.
