matt understands his client, very insightful and is an expert in his field. a “litigation hold letter” is a legal document that requires an individual or entity to preserve all documents, data, and information that may relate to a pending legal action that involves the person or company. also called a “preservation order,” the purpose of this letter is to keep all relevant pieces of evidence involved in the case safe and intact. a litigation hold letter during a divorce will likely come directly after the initial filing of the petition for dissolution of marriage in california. the letter may bear the title of “stop destruction request” or “preservation request.” either way, it will notify you of the anticipation of future litigation and give written instructions you must follow. these instructions will require you to preserve all electronic data, documents, and other records that could potentially serve as evidence in the upcoming case.
