You can write it yourself. A demand letter is literally what it says, letter that demands something. It's not legally significant. Most people don't take them seriously unless they're from a lawyer, though.
There is no legal requirement to respond to a demand letter, but don't brush it off – and don't make the decision to respond or not on your own. Just as drafting your own response can cause you legal trouble, so too can making the choice to respond or not without advice from legal counsel.
If you are trying to resolve a dispute, you may want to send a demand letter. You can write one yourself, but hiring an attorney will help you navigate legalities and show the recipient the seriousness of the matter.

All inmate mail must contain the sender's full name and complete return address, the inmate's full name (the name he/she is booked into jail under), the inmate's SPN, the inmate's housing facility and cell block location. If incoming mail does not have the above information on it, it will be returned to the sender.
The Nuts and Bolts of a Demand Letter Gather complete information before you start writing. Describe your injuries and medical treatment. List your medical expenses, lost wages, and non-economic damages. Make a settlement demand. Include a deadline for legal action if you want to, but don't bluff.
