Demand Letter Template for Attorneys

A demand letter is often the first formal step in resolving a legal dispute. Sent before litigation, it communicates your client's position, quantifies the claim, and gives the opposing party an opportunity to resolve the matter without the cost and uncertainty of a lawsuit. A well-crafted demand letter can accelerate settlement; a poorly written one can undermine your credibility.

This template provides a complete, annotated framework. Each section includes the purpose, sample language, and practical tips for adaptation.

Demand Letter Template

Letterhead and Date

Use your firm's official letterhead. The letter should be dated and sent via a method that provides proof of delivery.

[FIRM NAME]
[Address]
[Phone] | [Email] | [Website]

[Date]

VIA CERTIFIED MAIL, RETURN RECEIPT REQUESTED
AND VIA EMAIL TO [recipient@email.com]

Why certified mail? It creates a verifiable record of delivery, which matters if you later need to prove the demand was received — particularly for contractual notice provisions or prelitigation requirements.

Addressee

[Recipient Full Name]
[Title, if applicable]
[Company Name, if applicable]
[Address]

If the recipient is represented by counsel, the letter must be sent to counsel, not directly to the party. See Model Rule 4.2.

Re Line

RE: [Your Client's Name] — Demand for [Payment / Performance / Resolution]
    [Brief matter description]

Example:

RE: Greenfield Properties LLC — Demand for Payment of Past-Due Rent ($302,400)

Opening Paragraph

State who you represent, the purpose of the letter, and the relationship between the parties.

Sample:

This firm represents Greenfield Properties LLC ("Greenfield") in connection with the commercial lease agreement dated March 1, 2023 (the "Lease"), between Greenfield, as landlord, and Apex Retail Inc. ("Apex"), as tenant, for Suite 400, 1200 Main Street, Denver, Colorado 80202.

I write to demand payment of all past-due rent and related charges totaling $302,400, as detailed below. This letter constitutes formal notice pursuant to Section 12.3 of the Lease and C.R.S. 13-40-104.

Key elements:

• Identify your client
• Identify the opposing party
• Reference the contract, incident, or relationship giving rise to the claim
• State the purpose immediately — do not bury the demand

Statement of Facts

Present the facts that support the claim. Be detailed enough to demonstrate that you have investigated the matter, but do not reveal attorney work product or trial strategy.

Sample:

On March 1, 2023, Greenfield and Apex entered into the Lease for a five-year term commencing April 1, 2023. Under Section 4.1 of the Lease, Apex agreed to pay monthly rent of $24,000, due on the first day of each month.

Apex made timely rent payments from April 2023 through December 2024. Beginning January 1, 2025, Apex ceased all rent payments without notice or explanation. As of the date of this letter, Apex has failed to pay rent for twelve consecutive months (January 2025 through December 2025), totaling $288,000.

Section 7.2 of the Lease provides for a late fee of $500 per month for each month rent remains unpaid. Accordingly, Apex owes $6,000 in accrued late fees (12 months x $500). Additionally, Section 7.3 provides for interest on unpaid amounts at a rate of 1.5% per month.

Tips:

• Use chronological order
• Reference specific contract provisions, dates, and dollar amounts
• State facts, not legal conclusions — let the facts speak
• Do not exaggerate or misrepresent

Legal Basis

Explain the legal theories supporting the claim. Cite the relevant statutes, contract provisions, or common-law principles.

Sample:

Apex's failure to pay rent constitutes a material breach of the Lease under Colorado law. See Western Distrib. Co. v. Diodosio, 841 P.2d 1053, 1058 (Colo. 1992) (failure to pay rent is a material breach excusing further performance by the non-breaching party).

Section 12.1 of the Lease further provides that failure to pay rent within ten days of the due date constitutes an "Event of Default," entitling Greenfield to pursue all available remedies, including termination of the Lease, recovery of all unpaid rent, and recovery of attorney's fees and costs.

Tips:

• Cite authority, but do not write a legal brief — this is a demand letter, not a motion
• Focus on the strongest legal theories
• If there are multiple claims (breach, unjust enrichment, statutory violations), list them concisely

Damages Calculation

Itemize the damages clearly. Show your math.

Sample:

Greenfield's damages are as follows:

Interest and late fees continue to accrue.

The Demand

State exactly what you want, by when, and how payment or performance should be delivered.

Sample:

Greenfield hereby demands that Apex pay the full amount of $302,400.00 within thirty (30) days of the date of this letter, by certified check or wire transfer to:

[Bank name, routing number, account number, or "made payable to Greenfield Properties LLC and delivered to the address above"]

If Apex wishes to discuss a structured payment arrangement, Greenfield is willing to consider reasonable proposals, provided that any such arrangement is documented in a written agreement and includes appropriate security.

Tips:

• Be specific about the amount, deadline, and method of payment
• A 30-day response window is standard; shorter deadlines (10-14 days) may be appropriate when a statute of limitations is approaching
• If you are open to negotiation, say so — it demonstrates reasonableness

Consequences of Non-Compliance

State what will happen if the demand is not met. Be firm but professional.

Sample:

If Greenfield does not receive full payment or an acceptable payment proposal within thirty (30) days, Greenfield will pursue all available legal remedies without further notice, including filing a civil action for breach of contract, seeking recovery of all damages, attorney's fees, costs, and interest as provided by the Lease and applicable law.

Additionally, Greenfield reserves the right to terminate the Lease and pursue eviction proceedings under C.R.S. 13-40-104.

Tips:

• Do not threaten criminal prosecution to gain advantage in a civil matter — this is an ethical violation in most jurisdictions
• Do not make threats you are not prepared to carry out
• "All available legal remedies" is a safe, standard phrase

Reservation of Rights

Sample:

Nothing in this letter shall be construed as a waiver of any of Greenfield's rights or remedies under the Lease, at law, or in equity, all of which are expressly reserved.

Closing

Sample:

I trust this matter can be resolved without litigation. Please direct all communications to my attention at the address and email listed above.

Sincerely,

[Attorney Name] [Title] [Bar Number] [Phone] [Email]

Adapting for Different Practice Areas

Personal Injury Demand Letter

Replace the contract-based sections with:

• Liability facts: Description of the accident, negligent conduct, and causation
• Injuries and treatment: Detailed medical history post-incident, with provider names, dates, and diagnoses
• Damages: Medical bills (past and estimated future), lost wages, pain and suffering, loss of consortium
• Insurance information: Carrier name, claim number, policy limits (if known)

Employment Disputes

Include:

• Employment history: Start date, title, salary, performance history
• Discriminatory or retaliatory conduct: Specific incidents with dates
• Legal basis: Title VII, ADA, FMLA, state equivalents, EEOC charge number if filed
• Damages: Back pay, front pay, emotional distress, statutory penalties

Intellectual Property

Include:

• Description of the IP: Patent number, trademark registration, copyright registration
• Infringing conduct: Specific examples with dates, URLs, or product identifiers
• Cease and desist component: Demand to stop the infringing activity in addition to monetary damages

Common Demand Letter Mistakes

1. Being too aggressive. Bombastic language undermines credibility. Judges and opposing counsel see through it.
2. Being too vague. "You owe my client money" is not a demand. Specify the amount, the basis, and the deadline.
3. Revealing strategy. Do not disclose your litigation plan, your witnesses, or your theory of the case beyond what is necessary to support the demand.
4. Ignoring notice requirements. Many contracts and statutes require a specific form of notice before litigation. Check the contract and applicable law.
5. Sending to a represented party. If you know the opposing party has counsel, communicate through counsel only.
