How to Use These Templates

The templates below provide a starting framework for writing your demand letter. Each template uses bracketed placeholders like [YOUR NAME] that you replace with your specific information. While templates save time, you must customize them thoroughly to reflect your specific situation. A generic, clearly templated letter is less effective than a personalized one.

Before using any template, gather all your supporting documentation: contracts, invoices, receipts, photographs, correspondence, and any other evidence. The more specific details you include, the stronger your letter will be.

A few important notes about templates. First, no template can substitute for legal advice on complex claims involving multiple parties or novel legal theories. Second, templates work best for straightforward disputes where the facts are clear. Third, always verify that the template language is appropriate for your state, as legal requirements vary by jurisdiction.

Template Structure Overview

Every demand letter, regardless of the type of claim, follows the same basic structure:

Header: Your contact information, date, and recipient information
Subject line: Brief description of the claim
Opening paragraph: Who you are and the purpose of the letter
Facts section: What happened, in chronological order with specific dates
Legal basis: Why the recipient is legally responsible
Damages calculation: Exact amounts owed with breakdown
Demand: What you want and by when
Consequences: What you will do if the demand is not met
Closing and signature

This structure has been used successfully in hundreds of thousands of demand letters. It follows a logical progression that courts recognize and respect: establish the facts, explain the legal obligation, quantify the damages, and state your demand.

Unpaid Invoice Template

For freelancers, contractors, and businesses with unpaid invoices. This is the most common type of demand letter and has the highest success rate (65-75%) because the evidence is typically clear and well-documented.

Use the general template structure above with these specific modifications:

Facts section should include:
Date the contract or agreement was formed
Description of services performed or goods delivered
Confirmation that the work was completed satisfactorily (reference any sign-off or acceptance by the client)
Invoice number and date issued
Original payment terms (Net 15, Net 30, etc.)
Any partial payments already received
Dates of prior payment reminders sent (email on [date], phone call on [date], follow-up email on [date])

Damages section should include:
Principal amount of unpaid invoice(s)
Late fees per contract terms (typically 1-1.5% per month)
Interest at the rate specified in your contract (or your state's statutory prejudgment interest rate, typically 5-12% per year)
Collection costs if your contract includes a clause allowing recovery of these expenses

Specific language to include: "Per the terms of our agreement dated [DATE], payment was due within [NUMBER] days of invoice date. Invoice #[NUMBER] was issued on [DATE] with a due date of [DATE]. As of today's date, the invoice remains unpaid, and [NUMBER] days have elapsed past the due date."

Attach these documents:
Copy of the signed contract or agreement
Copy of the unpaid invoice(s)
Copies of prior payment reminders (emails, letters)
Any written acceptance or sign-off from the client confirming satisfactory completion

Security Deposit Demand Template

For tenants whose security deposit was wrongfully withheld. These letters have a strong success rate (60-70%) because landlord-tenant law heavily favors tenants when deposits are improperly withheld. Many states impose penalties of 2-3 times the deposit for willful violations.

Security deposit amount paid (and date paid)
Date you provided written notice of intent to vacate

Any partial refund received and any deductions claimed by the landlord
Why the deductions are improper (pre-existing damage, normal wear and tear, charges exceeding actual cost)

Legal basis should reference:
Your state's security deposit statute (e.g., California Civil Code 1950.5, New York GOL 7-108, Texas Property Code 92.103, Florida Statute 83.49)
The statutory deadline for return (varies by state: California 21 days, Texas 30 days, New York 14 days, Florida 15-30 days)
Penalties for failure to comply (many states allow 2-3x the deposit amount plus attorney fees)
The landlord's obligation to provide an itemized statement of deductions

Specific language to include: "Under [STATE] law ([CITE SPECIFIC STATUTE]), a landlord must return the security deposit or provide an itemized statement of deductions within [NUMBER] days of the tenant vacating the premises. I vacated the property on [DATE] and returned all keys. As of today, [NUMBER] days have elapsed, and you have failed to return my deposit of $[AMOUNT] or provide a compliant itemized statement. I am entitled to the return of my full deposit of $[AMOUNT] plus statutory penalties of [DESCRIBE PENALTY AMOUNT AND STATUTE]."

Customization Tips for All Templates

Be Specific With Dates

Replace every instance of [DATE] with actual dates. "On March 15, 2026" is far more effective than "earlier this year." Courts and opposing parties take specific dates seriously because they can be verified.

Attach Supporting Documents

List every document you are attaching in the "Enclosures" section. Include copies (never originals) of contracts, invoices, receipts, photographs, relevant emails, and repair estimates. If you reference a document in the letter, attach it. Number each attachment for easy reference (Exhibit A, Exhibit B, etc.).

Calculate Interest Correctly

If you are claiming interest, calculate it correctly. Check your contract first for a specified interest rate. If no rate is specified, use your state's statutory prejudgment interest rate. Common rates include: California 10%, New York 9%, Texas 5%, Florida approximately 5.52%.

To calculate simple interest: Principal x Annual Rate x (Days Outstanding / 365).

Example: $5,000 owed for 90 days at 10% = $5,000 x 0.10 x (90/365) = $123.29.

Set a Realistic Deadline

Standard deadlines are 14-30 days. For time-sensitive matters, 10 days may be appropriate. Giving less than 7 days may be viewed as unreasonable by a court, especially if the recipient needs to verify your claims. For security deposit claims where the statutory deadline has already passed, 14 days is standard.

State Only True Consequences

Only state consequences you are prepared to carry out. If you say you will file in small claims court, be prepared to do so. Empty threats destroy credibility and reduce the effectiveness of any future demand letters.

Formatting Best Practices

Use standard letter format on 8.5 x 11 inch white paper
Use a professional font (Times New Roman, Arial, or Calibri) in 12-point size
Single-space the body with double spacing between paragraphs
Use 1-inch margins on all sides
Left-justify the body text
Sign in blue or black ink
Print on clean, unwrinkled paper
Number pages if the letter is more than one page
If attaching multiple documents, label each as an exhibit and reference them in the body

After Sending Your Letter

Once you send your demand letter:

Keep the certified mail receipt and tracking number in a safe location
Save the green return receipt card when it comes back. This proves delivery.
Note the deadline on your calendar with a reminder 3 days before
Do not contact the recipient about the claim unless they contact you first. Let the letter do its work. Excessive follow-up can seem desperate.
If they respond with a counter-offer, evaluate it carefully against the cost of litigation before accepting or rejecting. Get any agreement in writing.
If the deadline passes with no response, follow through on your stated consequences. Consider sending a brief final notice giving 7-10 additional days before filing suit.
