How to Document Debt Collector Harassment and FDCPA Violations

It's 7:40 a.m. and your phone is buzzing — same number as yesterday. Last week they called your sister. There's a voicemail about "legal action" if you don't call back today. Some of that may be illegal. But knowing a collector broke the law and being able to prove it are two very different things. Proof is what makes a collector back off, what makes an attorney take you seriously, and what a judge will need.

First: does the FDCPA apply?

The FDCPA covers third-party debt collectors — agencies, debt buyers, and law firms that regularly collect for others — and only personal debts. If it's your original creditor collecting under its own name, the FDCPA generally doesn't apply (some states, like California, cover them). That's why the first thing you write down about every contact is the company's actual name.

What to watch for

• Timing: calls before 8 a.m. or after 9 p.m. your time.
• Frequency: more than 7 calls in 7 days about one debt, or a call within 7 days after a phone conversation — presumed harassment under Regulation F.
• Your job: calls at work after they know your employer prohibits them.
• Other people: telling family, friends, or coworkers about your debt.
• Threats: arrest, or lawsuits or garnishment they can't or won't pursue.
• The numbers: misstated balances or unauthorized fees.
• Language: profanity or abuse.
• Ignoring your letters: contact after a written cease request, or collection after a timely written dispute without verification.
• Your attorney: contacting you after learning a lawyer represents you.

The 7-part evidence file

Keep one paper folder and one computer folder, in date order.

1. The contact log

Every contact: date and time, number they called from and which of your numbers, company, name given, type (call, voicemail, text, email, letter), what was said, and any witnesses. Get as close to exact words as you can and put quotation marks around word-for-word quotes. "He said, 'If you don't pay today, we'll have you arrested'" is something an attorney can use. Write it right after the call ends.

2. Your phone's call history

Your log is your account; your call history is independent backup. Screenshot recent calls regularly with dates and times visible — phones only keep a limited history. Check whether your carrier lets you download call records. Missed calls count toward the 7-in-7 presumption.

3. Voicemails

Export each voicemail as an audio file to email or cloud storage and name it date-first ("2026-09-14 – CompanyName – voicemail"). A voicemail is the collector's own voice and words with a timestamp.

4. Recording calls — carefully

Federal law permits recording a call you're part of (18 U.S.C. § 2511(2)(d)), but some states, including California, Florida, Pennsylvania, and Washington, require everyone on the call to consent. The collector may be in another state. The safe approach: say "I'm recording this call" at the start. If they hang up, log it. Don't secretly record anyone before checking your state's law.

5. Letters, emails, and texts

Keep every letter with its envelope — postmarks help prove dates, like whether the validation notice arrived within five days of first contact. Lay letters side by side and note any unexplained changes in the balance. Screenshot texts and emails with date and sender visible.

For anything you send — a dispute or a cease letter — use certified mail with a return receipt, and keep a copy, the mailing receipt, and the delivery proof. Every later contact is measured against that date.

6. Your credit reports

Download all three reports from AnnualCreditReport.com as PDFs, date-named. A collector that reports information it knows is false, or reports a disputed debt without noting the dispute, may violate the FDCPA (§ 1692e(8)). You can't show that later unless you saved what your report said at the time.

7. Witnesses and what this is costing you

Ask anyone who got a call about your debt to write down who called, when, and what was said — signed and dated. Keep records of costs: missed work, a doctor's visit because of stress, changing your phone number. Actual damages have to be shown.

Mistakes that wreck a good file

• Embellishing. If your notes say they cursed and the recording shows they didn't, nothing else in your file will be trusted.
• Giving payment info to end a call. No card or bank numbers, no "I'll send something Friday."
• Paying or acknowledging old debts. In some states that can restart the statute of limitations.
• Ignoring a lawsuit. Evidence of collector misconduct doesn't make the debt disappear. If served, respond by the deadline.

Putting the file to work

1. CFPB complaint at consumerfinance.gov/complaint (attach documentation), your state attorney general, and the FTC at ReportFraud.ftc.gov.
2. A consumer attorney. A winning consumer generally recovers reasonable attorney's fees from the collector, so many attorneys review FDCPA cases free. Find one through NACA. Know that statutory damages top out at $1,000 and most courts read that as per lawsuit, not per violation; actual damages and fees are separate.
3. Put the collector on notice. A factual letter listing dates and sections, with nothing you can't back up.
