A professional letter to a court should be written in business-letter style and left-justified, the Law Dictionary advises. The information about the judge is first, followed by the sender's information and date of the letter. The writer begins with a proper salutation, notes his concerns in the body of the letter and ends with a proper closing.
The letter begins with the full name of the judge at the top of the page, the Law Dictionary says. The next line has the judge's address, and below that the address of the sender. The letter should be dated with the month, day and year. The proper salutation should begin with "Dear Judge" and follow with the judge's last name.
The body of the letter is next, and this is the area the writer states his concerns and reasons for addressing the court. The writer should identify himself as the defendant, the victim, a family member, other concerned party or an attorney, the Law Dictionary advises. If writing on behalf of the defendant's sentencing, indicate why a certain sentence should be granted. If writing on behalf of a victim, explain how the victim's life has changed since the crime.
The closing should be "Respectfully" or "Sincerely," followed by a comma and the writer's name. The writer should also sign his name to the letter, and proofread for grammatical and spelling errors.
