Tips for Writing the 15-Day Demand Letter

When writing the 15-day demand letter, you should follow a couple of useful tips to ensure the request is done in a clear and pleasant tone. Some of these tips to observe include;

  • Be polite: You should never attack the other party because this only triggers them to respond in an angry tone as well. Instead, be polite and calm while writing this letter as this shows you’re confident in your position. This will be beneficial should this matter eventually end up in the courts.
  • Use certified mail: Always send the demand letter for payment via certified mail with a return receipt. Having the return receipt will be of great help should this case find itself in court and the defendant tries to claim they didn’t receive the demand letter.
  • Create and keep copies: Make sure you have all the copies of the letter before sending it and having with your receipts from the post office. Also, don’t discard any correspondence from the opposing party.
  • State the facts: While it might look unnecessary as your adversary already knows what they’re being accused of, it’s always important you clearly mention all the facts. This is necessary as most people usually remember facts according to their perspective. By including the facts, you’ll be reminding them of everything as it happened to ensure you’re both on the same side.
  • State what you want: Be clear and mention what it’s exactly you want rather than beating around the bush. It’s advisable to request more than what you want as the opposing party will undoubtedly negotiate for a lower amount. Also, elaborate on how you reached the requested amount by stating the losses you incurred, including property damage, loss of income, medical visit costs and repair costs.

Sample 15 Day Demand Letter for Payment

March 20, 2021

Dear James Brown,

This letter is the formal request asking for the payment of $2000 in total rent, which is owed as of February 2021, when you rented one of my apartments, 672 Bell Street. New York, NY.

I also have attached a copy of the lease to help you when making your reference.

I have tried getting in touch with you several times by email (February 12, 2021and March 14, 2021) to no avail. Likewise, I have called your phone and left a few messages on February 15, 2021, and March 1, 2021.

As I am writing this letter, I am still yet to get any feedback from you.

If you do not make the full payment by March 31, 2021, you leave me no other choice as I will be forced to take legal action against you in the New York claims court.


Layla Bullock.
