The Consumer Problem Evidence Checklist
Written By: Brittany Munn When a product, service, repair, or home-improvement project goes wrong, the outcome may depend on what you can prove.
A consumer may remember exactly what a business promised, but memories alone are often not enough. Contracts, payment records, messages, photographs, estimates, and other documents can help establish what the business agreed to do, how it failed to perform, and how much the problem has cost.
Use this checklist to preserve and organize your evidence before sending a demand letter, filing a complaint, disputing a charge, or contacting an attorney.
Contract and Transaction Documents
Collect every document that describes the agreement, even if it was never formally signed.
Signed contract
Estimate or proposal
Invoice
Purchase receipt
Work order
Scope of work
Plans, drawings, or specifications
Change orders
Financing agreement
Warranty or service plan
Terms and conditions
Cancellation notice
Return or refund policy
Delivery confirmation
Electronic-signature record
Advertisements or promotional materials
Screenshots of the product or service description
Documents provided after the transaction
Save every version of the contract. Earlier drafts may show that important terms, prices, or promises were later changed.
Payment Evidence
Gather proof of every payment connected to the transaction.
Canceled checks
Credit-card statements
Bank statements
Cash receipts
Payment-app confirmations
Financing disbursements
Loan statements
Insurance-payment records
Deposit confirmations
Refund or credit records
Evidence of disputed charges
Collection notices
Create a short list showing the date, amount, payment method, recipient, and purpose of each payment.
If you paid in cash without receiving a receipt, write down when and where the payment occurred, who accepted it, and whether anyone witnessed it.
Written Communications
Preserve all communications with the business and its employees.
Emails
Text messages
Letters
Customer-service chats
Social-media messages
Portal messages
Appointment confirmations
Voicemails
Call logs
Written repair or completion promises
Refund offers
Settlement proposals
Messages acknowledging the problem
Messages acknowledging receipt of payment
Threats involving collections, liens, repossession, or legal action
Save complete conversations whenever possible. A single screenshot may not show the sender, date, or surrounding context.
Do not crop, edit, highlight, or annotate the only copy. Preserve the original and create a separate working copy if you want to add notes.
Telephone and In-Person Conversations
For important conversations that were not recorded in writing, create a communication log.
Include:
Date and approximate time
Names of the participants
Telephone number or meeting location
What you reported
What the business said
Promises or deadlines given
Any witnesses present
Whether you followed up in writing
After an important call, consider sending a brief email confirming your understanding of the conversation. For example: “This email confirms our conversation today in which you stated that the repair would be completed by September 15.”
Do not secretly record a conversation without first confirming that doing so is lawful. Recording laws may depend on where each participant is located.
Photographs and Videos
Photographs and videos can be critical in disputes involving construction, vehicle repairs, defective products, property damage, or unfinished work.
Document:
The overall condition
Each unfinished or defective area
Damage to surrounding property
Safety hazards
Error messages or warning lights
Model and serial numbers
Packaging and labels
Materials delivered to the property
Materials that appear incorrect or damaged
The condition before and after attempted repairs
The condition before another business changes the work
Preserve the original files because they may contain useful date, time, and location information. Back them up in more than one secure location.
Product and Physical Evidence
Do not discard physical evidence simply because it is broken or unusable.
Preserve, when practical:
The defective product
Replaced parts
Packaging
Labels
Instruction manuals
Warning information
Shipping materials
Samples of incorrect or damaged materials
Components removed during a repair
Receipts for storage or transportation
If the item must be returned, repaired, or disposed of, photograph it thoroughly first. Keep written records identifying who took possession of it, when it was transferred, and why.
Inspection and Repair Records
Independent professional evidence can help explain what went wrong and what it will cost to correct.
Collect:
Inspection reports
Diagnostic reports
Code-violation notices
Permit records
Failed inspection notices
Engineering reports
Mechanic’s findings
Contractor evaluations
Repair invoices
Completion estimates
Replacement estimates
Written professional opinions
Laboratory or testing results
Ask the professional to separate the cost of correcting the original problem from the cost of upgrades or unrelated improvements.
For unfinished construction, request estimates that distinguish between:
Completing the original scope of work;
Correcting defective work; and
Performing additional work that was not included in the original agreement.
Evidence of Your Financial Losses
Create a damages folder containing proof of every expense caused by the problem.
Potential losses may include:
Amounts paid to the original business
Cost of completing unfinished work
Cost of correcting defective work
Inspection or diagnostic fees
Temporary repairs
Replacement products
Damage to other property
Towing or storage charges
Rental vehicle expenses
Lodging expenses
Shipping expenses
Financing charges
Lost income
Permit or reinspection fees
Other documented out-of-pocket costs
Keep receipts, invoices, estimates, bank records, and proof of payment. A list of losses is helpful, but supporting documents make the claim stronger.
Information About the Business
Identify the correct person or company responsible for the transaction.
Gather:
Legal business name
Trade or “doing business as” name
Business address
Mailing address
Telephone number
Email address
Website
Names and titles of employees involved
Name shown on the contract
Name shown on payment records
State business-registration records
Professional license information
Contractor-registration information
Insurance information
Bond information
Registered-agent information
Bankruptcy or business-closure notices
The company name used in advertising may be different from the legal entity that entered the contract or accepted payment.
Complaints and Third-Party Records
Preserve complaints made to other organizations and every response you received.
This may include records from:
The Ohio Attorney General
The Indiana Attorney General
The Better Business Bureau
A professional licensing board
A local building department
A manufacturer
A dealership
A financing company
A credit-card issuer
An insurance company
A credit-reporting agency
A debt collector
Law enforcement
An online marketplace
Save confirmation numbers, attachments, responses, and decisions.
Remember that filing a complaint with an agency or private organization may not extend the deadline for filing a lawsuit.
Evidence of What the Business Promised
Consumer disputes often involve promises that do not appear in the final contract.
Preserve evidence of representations concerning:
Price
Quality
Materials
Completion dates
Product condition
Experience or qualifications
Licensing or insurance
Warranties
Expected results
Availability of parts
Refunds
Financing
Insurance coverage
Whether work was necessary
Whether a product was new, used, or refurbished
Include advertisements, website screenshots, emails, texts, brochures, and notes from sales presentations.
If a representation was made orally, write down who made it, when it was made, where it occurred, the words used as accurately as you can remember them, and who else heard it.
Evidence That the Business Knew About the Problem
It is important to show when the business received notice and how it responded.
Collect:
Your initial complaint
Delivery confirmation for written notices
Requests for repair or completion
Requests for a refund
Photographs sent to the business
Inspection reports provided to the business
The business’s acknowledgment
Scheduled repair appointments
Missed appointments
Promises to investigate
Repair attempts
Denials of responsibility
Offers to resolve the dispute
Refusals to communicate
Keep proof showing when each notice was sent and received.
A Written Timeline
Create a timeline containing the most important events in date order.
Include:
First contact with the business
Contract date
Payment dates
Delivery or performance dates
Date the problem appeared
Date you reported it
Repair attempts
Promised completion or refund dates
Agency complaints
Demand letters
Collection activity
The business’s last response
Keep the timeline short and factual. Attach supporting evidence separately instead of placing every detail in the timeline.
Your Requested Resolution
Write down what you want the business to do.
Possible resolutions include:
Complete the work
Correct defective work
Replace the product
Refund the purchase price
Reimburse repair expenses
Cancel the contract
Release you from financing
Remove an inaccurate charge
Correct credit reporting
Release a mechanics’ lien
Pay for damaged property
Stop collection activity
Enter into a mutual release
Your preferred resolution may change after legal review, but identifying it helps focus the initial demand or consultation.
Evidence to Preserve Even If It Appears Unhelpful
Do not discard evidence simply because you believe it may weaken your claim.
Preserve:
Messages showing delays on your part
Complaints from the business
Missed appointments
Unpaid invoices
Contract provisions you disagree with
Repair offers you rejected
Negative inspection findings
Communications written when you were angry
Evidence of prior damage
Documents showing that part of the work was completed
An attorney needs the complete picture to assess the strengths and risks of the case. Unfavorable evidence is usually easier to address when it is identified early.
Evidence You Should Not Create
Preserving evidence is different from manufacturing it.
Do not:
Alter photographs
Edit original messages
Re-create receipts
Backdate documents
Pretend a new note was written at the time of the event
Ask a witness to change their account
Post exaggerated accusations online
Continue unnecessary communications merely to provoke a response
Secretly access another person’s account
Record conversations without determining whether it is lawful
You may prepare a new written summary based on your recollection, but clearly label it with the date it was created.
Organize the Evidence
Create one main folder with clearly labeled subfolders:
Timeline and Summary
Contracts
Payments
Communications
Photos and Videos
Inspections
Repair and Completion Estimates
Damages
Business Information
Complaints and Responses
Use filenames that include a date and description:
2026-04-10 Signed Contract.pdf
2026-04-15 Deposit Confirmation.pdf
2026-05-20 Text Promising Completion.pdf
2026-06-01 Photos of Defective Flooring
2026-06-10 Independent Repair Estimate.pdf
Clear filenames make the evidence easier to review and reduce the time spent searching for important information.
Bring These Key Items to a Lawyer First
You do not necessarily need to send hundreds of documents before the initial consultation.
Start with:
A one-page timeline
The contract
Proof of payment
The most important communications
Representative photographs
An inspection report, if available
A repair or completion estimate
A summary of your financial losses
Any demand letter and response
Any court filing, lien, collection notice, or document containing a deadline
Tell the attorney what additional evidence exists and how it is organized.
2026-04-10 Signed Contract.pdf
2026-04-15 Deposit Confirmation.pdf
2026-05-20 Text Promising Completion.pdf
2026-06-01 Photos of Defective Flooring
