Legal service is about time and knowledge. As a practical matter, time becomes the unit of measure. Talk with the lawyers about their fees and billing practices. For example, ask if you will be charged for telephone consultations, copying and other document services, and travel. Be sure to ask when payment is due.
Nothing is more unpleasant, for a client and the attorney, than a misunderstanding about billing.
Make sure you understand the client and fee agreement. In nearly every case, you will enter into the attorney-client relationship through a contract outlining the scope of the services to be provided and the fees for providing them. It s the business foundation of your relationship. Be sure it reflects your understanding of the arrangements. If something is not clear, ask.
