Your Rights Under Federal Law

The FDCPA protects you from abusive debt collection practices. Debt collectors must follow strict guidelines when contacting you.

No Harassment or Abuse

Collectors cannot harass, oppress, or abuse you in any way. They cannot threaten violence or harm to you or anyone else.

No False or Misleading Statements

Collectors cannot lie about the amount you owe. They cannot misrepresent your legal options or pretend to be someone else.

No Calls at Inconvenient Times

Debt collectors cannot contact you before 8 a.m. or after 9 p.m. They must stop calling if you request it in writing.

No Sharing Your Information

Collectors cannot disclose your debt to others. Your employer cannot be contacted. They may only speak with your attorney or spouse.

Capital One owes you compensation if they violated these rules. Visit our guide on FDCPA violations to understand your rights.

What to Do If Capital One Sues You

Capital One may escalate collection efforts by filing a lawsuit. Ignoring a lawsuit guarantees you lose.

You must respond within the deadline stated on your summons. Most states give you 20-30 days to file an Answer.

Our partner Solo helps you prepare your legal response. The process takes about 15 minutes online.

Your Answer should address each claim in the complaint. You can raise defenses like:

  • Statute of limitations expired
  • Debt amount is incorrect
  • You already paid the debt
  • The debt belongs to someone else
  • Lack of proper documentation

Filing your Answer protects your rights in court. It forces Capital One to prove their case with evidence.

Negotiate a Settlement with Capital One

You can often settle for less than you owe. Capital One may accept 40-60% of the original debt.

Start by requesting debt verification. Capital One must prove they own the debt and the amount is accurate.

Make a realistic offer based on your budget. Get any settlement agreement in writing before paying.

Our partner Solo can help you negotiate and document your settlement properly.

Block the Number as a Last Resort

Blocking 800-955-6600 stops the immediate annoyance. Most smartphones include built-in blocking features.

However, blocking doesn’t solve the underlying debt problem. Capital One can still sue you or use other numbers to call.

Use blocking alongside other strategies, not as your only solution.

Start with a verbal request to stop calling. Follow up with a written cease and desist letter.
