She or he is not trained for that role and it is expensive. Sometimes one's emotions can affect the legal divorce process in a way that is harmful to that person's and the children's best interest. One may urge his or her lawyer to do frivolous and expensive motions because that person is experiencing intense anger towards one's spouse. Be aware of such behavior. Keep good notes.
Information is power.
The more information you can provide your attorney, the better she or he can represent you. It is important for your attorney to understand your unique situation and needs. It will also save you legal fees. Instead of spending hours in conferences explaining your case at billable hours, you can hand your lawyer a package of information for her or him to review. Write about your marital history, contributions to the marriage, and the finances of the marriage.
