I need to get a lawyer to get custody of my year and half son. His mother is not capable of taking care of him. How do I go about getting one

What you would need is to request the court for Primary Custody of your son based on the circumstances you are alleging. If there is a custody order already in place you can request the court for modification. As a general rule of thumb, you can represent yourself in court and save the costs of an attorney by using a paralegal to draft the court forms. However, if you do chose to hire a lawyer in Arizona, you can expect to pay anywhere from $3,000 or so. I am licensed in New York and New Jersey.
