Sued by a Debt Buyer in Arizona? What Midland, LVNV, Portfolio Recovery, and Cavalry Must Prove

If the company suing you is one you have never heard of — names like Midland Funding, LVNV Funding, Portfolio Recovery Associates, or Cavalry SPV — you are almost certainly being sued by a debt buyer. Debt buyers purchase large portfolios of old, defaulted accounts from original creditors at steep discounts, then file mass lawsuits to collect the full balance. They are not the bank or card issuer that originally extended you credit. That distinction matters, because the further a collector is from the original creditor, the harder it becomes to produce complete documentation.

A note on entities: some of these companies operate through related legal entities with similar names. Check the exact legal name of the plaintiff on your summons and verify it matches any assignment records the plaintiff produces.

Proof requirement 1 — Chain of title: they must prove they own your debt

The foundation of any debt buyer's case is proving they have the legal right to collect. They must establish a complete, unbroken chain of assignment from the original creditor to the current plaintiff. Every transfer in that chain must be documented with a bill of sale or assignment agreement that specifically identifies your account.

The challenge: debts are routinely sold multiple times. If a bank sold a portfolio to Company A, which sold it to Company B, which is now suing you as the current plaintiff, every link must be documented. A missing assignment, a bill of sale that covers a general portfolio without specifically identifying your account, or an assignment referencing a different entity name are all gaps in the chain — and a gap is a defense you can raise in your Answer.

Proof requirement 2 — The correct amount

A debt buyer must prove the amount they are claiming is accurate. Debt portfolios are purchased with electronic records that are sometimes incomplete or out of date. Buyers sometimes add interest, fees, or charges after the account was purchased that may not be authorized by the original credit agreement. Compare the amount in the complaint against any account statements you have from the original creditor. If the balance has been inflated, challenge it explicitly in your Answer.

Proof requirement 3 — The statute of limitations has not run

Debt buyers frequently purchase very old accounts — sometimes accounts that are already past Arizona's limitations period. Under A.R.S. § 12-548(A), creditors have 6 years to sue on a written contract or credit card debt, generally from the date of the first missed payment. If that period has run, the lawsuit is time-barred. But you must raise this defense in your Answer — the court will not apply the SOL on your behalf. See the Arizona statute of limitations guide (linked below) for details on how the clock runs and when it may restart.

Your FDCPA rights: debt validation

Debt buyers are "debt collectors" under the federal Fair Debt Collection Practices Act (FDCPA). The FDCPA gives you the right to request written verification of a debt within 30 days of the collector's first written communication to you. After a timely validation request, the collector must stop collection efforts until they provide written verification and, if requested, the name and address of the original creditor. A debt validation request is separate from your court Answer — do both.

The FDCPA also limits what debt buyers can say during collection. A collector who files a lawsuit knowing the debt is time-barred, or who makes false statements about the amount owed, may be violating the FDCPA. Whether a specific act violates the FDCPA is fact-specific — consult a licensed Arizona attorney if you believe the collector has crossed a legal line.

What to do when you are sued by a debt buyer in Arizona

1. Read the complaint carefully. Who is the plaintiff — exact legal entity name? Does the complaint include documentation of the chain of assignment? Is the amount consistent with your records?
2. Check the Answer deadline. In Arizona Justice Court (cases involving $10,000 or less), you have 20 days from the date of service to file a written Answer. Do not miss it.
3. File a written Answer. Deny what you dispute and raise your affirmative defenses: statute of limitations, lack of standing (no complete chain of assignment), incorrect amount, and any FDCPA violations.
4. Send a written debt validation request. If the lawsuit is your first written contact from the collector, send the validation request now — and also file your Answer with the court.
5. Request documents in discovery. Once you have answered, you can formally request the original credit agreement, account statements, and all assignment records. Many debt buyers settle or drop cases rather than produce complete documentation.

What this does not do

Successfully challenging a debt buyer's documentation may get the lawsuit dismissed — it does not make the underlying debt disappear. Winning a time-barred-debt defense gets the lawsuit dismissed; the underlying debt still exists. The creditor can still attempt to collect through other means within FDCPA limits.
