Dispute letters, explained like you're 5
Four kinds of dispute letter in plain words, what to include and gather, and a labeled sample letter about a security deposit. It never says who is in the right or what to demand.
Explain it like I'm 5
A dispute letter is a short written note that says what happened and what the writer is asking for. It is like a clear note someone can read later. Having it in writing with proof makes the facts clear. The rules that decide the outcome come from your state, your card issuer, or the court.
This explains. It does not advise.
Where all four AIs agree is the solid ground. Where they disagree is exactly what to ask your state consumer protection office, a tenant organization or legal aid, your card issuer, or the small claims court clerk. This guide never says who is in the right, what you will win or what to demand: a letter states facts and asks, and your state's rules decide the rest.

Four kinds of dispute
Not good versus bad: what each letter should include and what weakens it.
Security deposit
A security deposit is money paid for a rental. This letter asks a landlord to return the deposit or explain deductions in writing. State law decides what is allowed, so ask a tenant organization, legal aid, the state consumer protection office, or a lawyer licensed in your state.
What to include
- Gather the lease, proof of payment, rental address, move-out date, forwarding address, and photos.
- Include the deposit amount and ask for the deposit back or an itemized list of deductions.
What weakens a letter
- Missing payment proof, move-out details, or a mailing address.
- Guesses, accusations, or unsupported claims about deductions.
Landlord repairs
This letter reports a problem in a home and asks for it to be fixed. State law and the lease decide what is allowed, so ask a tenant organization, legal aid, the state consumer protection office, or a lawyer licensed in your state.
What to include
- Describe the problem, location, start date, effects, and preferred way to reach you.
- Gather dated photos, earlier messages, call notes, access records, and the lease repair section.
What weakens a letter
- Vague descriptions without a room, date, or clear explanation.
- Relying only on calls.
Chargebacks and card disputes
A chargeback or card dispute asks a card issuer to review a charge. The card's own statement and the issuer set the dispute steps, so read the statement and ask the issuer.
What to include
- Include the statement entry, charge date, amount, account details, and reason for the dispute.
- Gather the statement, receipts, order records, messages, cancellation or return records, and earlier contact.
What weakens a letter
- Using the wrong address or ignoring the statement's dispute instructions.
- Dates or amounts that do not match the statement, or missing copies and delivery proof.
Small claims
A small claims court is a court for smaller money disputes. Its rules and money limits differ by place, so ask the court clerk about local forms and steps.
What to include
- Write a short timeline, identify the money dispute, and gather contracts, receipts, photos, messages, and letters.
- Ask the court clerk which forms, filing steps, and local requirements apply.
What weakens a letter
- Assuming another place's forms, limits, or filing steps apply.
- Missing records, copies, or proof of delivery.
Rules to know
- A credit card billing error
- The CFPB says to send a written notice to the card company no later than 60 days after it sent the statement where the error first appeared, using the address in your bill's instructions (it can differ from the payment address), with your name, address, account number and a clear explanation, and to keep a copy. The company has 30 days to tell you it got your letter and another two billing cycles to finish looking into the dispute. You do not have to pay the disputed charge while it does, but you still must pay correct charges on time. The page was last modified June 4, 2025.

- A debit card or bank transfer error
- For an unauthorized debit card or other electronic fund transfer, the CFPB says to notify your bank or credit union no later than 60 days after it sends the statement that shows the transaction. Once notified, it generally has ten business days to investigate (20 if the account is under 30 days old), must correct an error within one business day of finding one, and must generally resolve the issue in 45 days, or up to 90 days in some cases.

Common mistakes
- Leaving out dates or identifying details makes it unclear which event, home, deposit, or charge you mean.
- Using angry labels instead of facts can distract from the question and weaken the explanation.
- Sending original records can leave you without documents when you need them later.
- Skipping delivery proof makes it harder to show what was sent and when.
- Assuming state, issuer, and court procedures are the same everywhere can cause a missed step.
Questions to ask before you send it
Ask your state consumer protection office, a tenant organization or legal aid, your card issuer, or the small claims court clerk.
- Landlord: Where should I send my written deposit request or repair report?
- Card issuer: Which statement instructions, address, or process applies to my dispute?
- Court clerk: Which forms and local steps apply to this small claims matter?
- Tenant organization: Which state rules and records matter for my deposit or repair question?
- Legal aid: Can someone review my housing letter and explain the state rules?
- State consumer protection office: Which office handles this type of consumer question?
