Dear Mr. Thompson,

Your account with ABC Marketing Services shows an outstanding balance of $12,850 for services rendered between September and December 2023. Despite multiple payment reminders sent on January 15, February 1, and February 15, 2024, this amount remains unpaid.

Our records show you have received all deliverables as outlined in the contract, including monthly performance reports, ad campaign analytics, and optimization recommendations.

This letter serves as formal notice that unless the full payment of $12,850 is received within 14 days from the date of this letter, ABC Marketing Services will pursue legal action to recover the debt. Additional costs including late payment fees, legal expenses, and court costs may be added to the amount owed.

To resolve this matter promptly and avoid legal proceedings, please arrange payment through any of these methods:

  • Bank transfer to Account #2458-9012, routing #012345678
  • Credit card payment through our secure client portal

2. Notice to Landlord Regarding Security Deposit Return

Subject: Notice of Intent to Pursue Legal Action – Unreturned Security Deposit

Dear Ms. Anderson,

This letter addresses the unreturned security deposit of $2,500 for apartment 3B at 789 Oak Street, which has now been overdue for 45 days since the lease termination on January 8, 2024.

According to state law, landlords must return security deposits or provide an itemized list of deductions within 30 days after a tenant moves out. The apartment was left in excellent condition, as documented in the move-out inspection report signed by your property manager, David Chen, on January 8, 2024. Photos and videos taken during the inspection confirm all items on the move-out checklist were satisfactorily completed.

Multiple attempts to reach you about this matter have gone unanswered, including emails sent on January 25, February 1, and February 10, 2024. Phone messages left with your office on February 5 and February 12 also received no response.

Please be advised that unless the security deposit is returned in full within 10 business days from the date of this letter, legal action will be initiated to recover:

  • The full security deposit amount of $2,500
  • Additional penalties allowed under state law for wrongful withholding
  • Legal costs associated with pursuing this matter in small claims court

Send the security deposit refund to: Robert Martinez 456 Pine Street, Apt 2C New York, NY 10002

Looking forward to resolving this matter without court intervention. Please contact me at 555-0187 or robert.martinez@email.com if you need additional information.

Thank you for your prompt attention to this issue.

Best regards,
Robert Martinez

3. Notice to Neighbor Regarding Property Damage

Subject: Notice of Legal Action – Property Damage from Tree Removal

Dear Mr. and Mrs. Baker,

This letter concerns the significant damage caused to my property at 234 Maple Drive during your tree removal project on February 1, 2024. The incident resulted in several broken fence panels, crushed landscaping, and a cracked concrete patio.

A professional contractor has assessed the damage, estimating repair costs at $4,750. This includes:

  • Fence repair and replacement: $1,800
  • Landscaping restoration: $1,200
  • Concrete patio repair: $1,750

Photos documenting the damage and the contractor’s detailed estimate were shared with you via email on February 3, 2024. Your tree service company’s supervisor, Tom Wilson, also witnessed the damage and acknowledged it in writing on the day of the incident.

While understanding this was unintentional, the damage significantly impacts the use and value of my property. Despite our conversation on February 2 where you verbally agreed to cover the repair costs, no payment has been received.

Legal action will begin if full compensation is not arranged within 14 days from this notice date. Court proceedings may result in additional costs being added to the repair amount, including:

  • Court filing fees
  • Legal representation costs
  • Any additional damage discovered during repairs

To avoid legal proceedings, please contact me at 555-0199 or jane.smith@email.com to arrange payment or discuss an acceptable payment schedule.

Subject: Legal Notice – Breach of Contract for Home Renovation Project

Dear Mr. Reynolds,

This letter addresses the incomplete renovation work at 567 Cedar Lane, contracted under agreement #HRC-2024-156, dated November 15, 2023. The project, scheduled for completion by January 30, 2024, remains substantially unfinished with numerous defects in the work completed thus far.

Outstanding issues include:

  • Kitchen cabinets improperly installed with visible gaps and misaligned doors
  • Bathroom plumbing fixtures left unconnected

The contract specified a completion timeline of 10 weeks with a total project cost of $45,000, of which $35,000 has already been paid in scheduled installments. Your crew has not been on-site since February 1, 2024, and you have not responded to phone calls or text messages since February 5, 2024.

A licensed home inspector has documented all incomplete and defective work, estimating an additional $18,500 needed to properly complete the project. This evaluation is available for your review.

Unless you resume work within 7 days and provide a detailed completion schedule, legal action will commence seeking:

  • Refund of payments for incomplete work
  • Costs for hiring replacement contractors
  • Compensation for extended temporary housing expenses
  • Legal fees and court costs

Dear Claims Department Manager,

This letter concerns claim #MED-2023-78901, submitted on December 15, 2023, for emergency gallbladder surgery performed at City General Hospital on December 10, 2023. Your denial letter dated January 25, 2024, cited “pre-existing condition” as the basis for rejection.

  • Surgical procedure: $18,000
  • Hospital stay (2 days): $6,000

Your denial has caused significant financial hardship and unnecessary stress during recovery. Unless this claim is properly processed and paid within 21 days, legal proceedings will begin seeking:

  • Full payment of medical expenses
  • Interest on delayed payment
  • Compensation for emotional distress
  • Legal expenses and court costs

Direct your response to: Patricia Chen 789 Birch Street Chicago, IL 60601
