Type this question into a search engine and you will get three kinds of answers priced three different ways, usually without anyone explaining the difference. Here is the honest map.
Option one: the free or cheap template. Cost: $0 to roughly $50. You download a form, fill in the blanks, and mail it yourself. What you get is a letter, and sometimes that is genuinely enough, a clearly-owed debt, a counterparty who just needed to see the request in writing. What you do not get: any check that you cited the right statute (or any statute), any computation of what the law actually entitles you to, and, most importantly, any signal to the recipient that a lawyer has looked at the claim and found it real. Recipients, and their lawyers, can tell the difference between a template and counsel, and they price their response accordingly. The risk is not that a template letter is worthless; it is that it spends your one first impression cheaply.
Option two: the flat-fee attorney letter. Cost: on this site, $349 to $499 depending on the letter, and other flat-fee services price in a broadly similar range. A licensed attorney reviews your facts, drafts a letter citing the specific statutes that govern your dispute, computes the amounts, statutory damages, interest, and fee-shifting exposure, signs it on law firm letterhead, and it mails with tracking. The economics work because the drafting is systematized while the legal judgment is not: the attorney reviews and signs every letter, but you are not paying an hourly meter for the parts a system does well. For the common New York disputes, deposits, invoices, wages, collectors, this is usually the rational middle: attorney weight at a price that makes sense for a four-figure dispute.
Option three: traditional hourly counsel. Cost: New York attorneys commonly bill several hundred dollars per hour, and a demand letter engagement, intake, review, drafting, revisions, can plausibly run from several hundred dollars into the low thousands depending on complexity. That is not a ripoff; for complex matters it is correct. If your dispute involves genuinely contested facts, a counterparty with lawyers already engaged, potential counterclaims, or very large amounts at stake, you want counsel who will master the whole file and stay with it into litigation if needed. Paying hourly rates for a routine security deposit demand, on the other hand, can cost more than the deposit.
How to choose. Ask three questions. Is the law clear and the amount documented? Templates start to become viable, and flat-fee letters are strongest, when yes. Is the amount at stake large relative to the fee? A $349 letter chasing a $3,000 deposit is proportionate; a $2,000 hourly engagement chasing it is not. Does the dispute have layers, contested facts, ongoing relationships, real litigation risk? Then pay for hourly counsel and do not look back. One more honest note: whatever route you choose, the letter's cost matters less than its accuracy. A demand that miscites the law or inflates the number hands the other side an easy reason to ignore it. Price is what you pay once; credibility is what the letter spends on arrival.
Because the process around the attorney is systematized: guided intake, statutory templates, and automated mailing. The attorney's review and signature stay; the hourly meter for everything around them goes.
Attorney review of your intake, a letter drafted and signed by a licensed New York attorney, computation of amounts and statutory damages, mailing with tracking, and a PDF copy, at $349 to $499 depending on the letter.
Sometimes, when the amount is small, the debt is undisputed, and the recipient just needs the request in writing. The tradeoff is that a template carries no attorney signal and no check that the law is cited correctly.
When facts are genuinely contested, the other side has counsel engaged, counterclaims are plausible, or the stakes are large. Complex matters deserve an attorney who owns the whole file, not a flat-fee product.
