I am writing this letter on behalf of a former student of mine who is presently before you on criminal charges and is due to be sentenced shortly. Dear judge (name), I am writing to ask for leniency in the sentencing of my husband, because (then give all your reasons and speak only from your heart).Explain why you feel you deserve leniency. How should you start a leniency letter? The core of your letter should explain why you believe the judge should show leniency towards the defendant. A character letter to a judge should establish your credibility, paint a full picture of the defendant and be respectful, among other things. In this article, we will discuss how to write a formal letter to a judge, along with the proper format and a sample letter. A character letter is designed to show support for a defendant in a criminal case. These letters have the potential to influence the court. I am writing this letter behalf of my dear friend Princewill Johnson.
