Common Mistakes When Filing a Class Action Claim

Most lost settlement payments come down to a handful of avoidable mistakes. Here's what they are and how to avoid each one.

The most common mistakes when filing a class action claim are filing too late, misreading the class definition, entering wrong payment or contact details, ignoring deficiency notices, filing duplicates and filing on a fake website. Each one can cost you your payment, and each is easy to avoid with a few minutes of care.

1. Waiting until the deadline

Settlement websites can slow down near deadlines, and life gets in the way. If you file at the last minute, you also have no time to respond if something goes wrong. File as soon as you know you qualify. Our guide to tracking settlement deadlines covers simple systems.

2. Not reading the class definition

The class definition decides who qualifies. It usually names a product or service, a time period and sometimes a location. People often assume they qualify because they used the brand, when the settlement only covers a specific product line, a specific state or a specific date range. Read the definition on the official site before filing.

3. Typos in payment details

Electronic payments go wherever you tell them to. A mistyped email or phone number for PayPal, Venmo or Zelle can mean your payment fails or goes to the wrong account. A wrong mailing address means your check goes astray. Double-check these fields before submitting.

4. Using contact details you won't keep

Payments can come many months after you file. If you use a work email, a temporary address or a phone number you're about to change, you may miss updates or payment. If you move after filing, update your address with the administrator. See how to update your address on a claim.

5. Ignoring a deficiency notice

If something is missing or unclear, the administrator may send a deficiency notice asking you to fix it by a set date. These often land in spam. If you don't respond in time, your claim can be denied. Check your email, including spam, for a few weeks after filing.

Deficiency notices have their own deadline

The deadline to cure a deficiency is separate from the claim deadline and can be short. Respond as soon as you see the notice, with exactly the information it asks for.

6. Filing more than once

Submitting the same claim twice, perhaps because you weren't sure the first one went through, can get both flagged as duplicates. If you're unsure whether your claim was received, check your confirmation email or contact the administrator instead of filing again.

7. Filing on a fake or unofficial site

Scam sites copy settlement names to collect personal information or charge fees. Real claims are filed on the official administrator's site, and filing is free. Find the official site from a trustworthy source, and be cautious with links in unexpected texts.

8. Choosing the wrong tier

Many settlements offer a basic no-proof tier and a higher documented tier. People with receipts or records sometimes choose the basic tier out of habit and leave money behind. Others choose the documented tier without attaching documents and get bumped down or rejected. Pick the tier that matches what you can actually show.

9. Overstating the claim

Inflating purchases or losses isn't just a mistake, it's a false statement under penalty of perjury, and administrators screen for it. Give honest, good-faith estimates. See what happens if you lie on a claim form.

10. Not saving the confirmation

Without your claim ID or confirmation, it's much harder to check your status or fix a problem later. Screenshot or save the confirmation page and keep the email.

11. Letting the check expire

Settlement checks often expire after a set period printed on the check. If you set it aside and forget, the money may be redistributed or sent elsewhere. Deposit checks as soon as they arrive. Our guide on cashing a settlement check has tips.
