The greeting "Dear Mr." or "Dear Ms." is followed by the lawyer's last name. After the salutation, add a colon. Then mention the person to whom you are writing. In English-speaking countries, it is common practice for attorneys to use their titles when writing to them. Thus, an email to the attorney will be addressed to "Mr. Smith" or "Mrs. Jones". The recipient does not have to respond to your message, but it is polite to include their title in your letter or email. In some states, lawyers are required by law to give their clients a legal document called a "letter of representation" before they start work on any matter for you. The letter informs your prospective attorney that you wish to seek his or her advice and assistance, that you have requested information about his or her background and experience, and that you would like him or her to represent you in your case. If your attorney is unable to provide this document for you, then he or she cannot formally enter an appearance on your behalf. In other states, lawyers are permitted to begin working for you without first sending you a letter of representation. But regardless of how your attorney starts working for you, it is important that you get him or her on your case as soon as possible.
