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. At the end of a character letter, most writers make an "ask" of the court.A character letter to a judge should establish your credibility, paint a full picture of the defendant and be respectful, among other things. The character reference letter for court serves the purpose of offering the Judge insights into the Defendant's moral or mental attributes. Explain why you feel you deserve leniency. I am writing this letter behalf of my dear friend Princewill Johnson. Mr. Princewill and I have been close friends over 10 years now. In this article, we will discuss how to write a formal letter to a judge, along with the proper format and a sample letter. At the start of the letter, introduce yourself and explain how you know the defendant. When writing your letter, you'll want to focus on factors that might persuade the judge to be more lenient in their sentencing.
