Reg Z / TILA, Part 1: Open-End and Credit Cards

Truth in Lending is the biggest single body of consumer-credit law on this exam, so we'll split it across two lectures. The Truth in Lending Act, at fifteen U-S-C sixteen-oh-one, and Regulation Z at twelve C-F-R part ten twenty-six, exist to make the cost of credit transparent and comparable. Reg Z divides the world into two buckets: open-end credit, like credit cards and home-equity lines, where the consumer can borrow repeatedly up to a limit, and closed-end credit, like a car loan or a mortgage, with a fixed amount and term.

This lecture covers open-end credit. The next covers closed-end and mortgages. The disclosure machinery differs between them, and the exam tests whether you know which bucket you're in.

Two terms anchor all of Reg Z. The finance charge is the total dollar cost of credit, the interest plus certain fees the consumer pays to get the loan. The Annual Percentage Rate, the A-P-R, expresses that cost as a yearly percentage, so a consumer can compare offers.

Reg Z requires both to be disclosed accurately, and there are tolerances for how far off a disclosed figure can be before it's a violation. The exam frequently asks whether a particular fee is part of the finance charge, application fees, certain insurance, points, or excluded. Learn the finance-charge concept well; it drives the A-P-R, and the A-P-R drives much of what the exam asks.

A useful rule of thumb: a charge is part of the finance charge if it's imposed by the creditor as a condition of, or incident to, the extension of credit, interest, points, and certain mandatory fees qualify, while charges that would be paid in a comparable cash transaction, like taxes or certain third-party fees, generally don't. The exam will test borderline fees, so when you see a fee, ask whether the consumer is paying it because they're borrowing. If yes, it's likely in the finance charge.

For open-end credit, particularly credit cards, Reg Z requires a sequence of disclosures. At the application or solicitation stage, the consumer gets a standardized table, often called the Schumer box, summarizing the A-P-R, fees, and key terms. At account opening, fuller disclosures follow.

Then periodic statements lay out the balance, payments, interest, and fees each cycle. And before changing significant terms, the issuer must send a change-in-terms notice, generally forty-five days in advance for credit cards. The exam likes to test the forty-five-day advance notice and the content of the periodic statement, including how payments are allocated.

Keep the open-end disclosure timeline straight from the closed-end one we'll cover next.

The Credit Card Accountability, Responsibility, and Disclosure Act of 2009, the CARD Act, layered strong protections into Reg Z, and the exam tests them. Issuers generally can't raise the rate on an existing balance except in limited circumstances, and rate increases on new transactions require forty-five days' notice. Statements must be mailed so the consumer has at least twenty-one days before the due date.

When a consumer pays more than the minimum, the excess must be applied to the highest-A-P-R balance first. Issuers must assess the consumer's ability to pay before opening an account or raising a limit, and there are special rules for applicants under twenty-one. When a card question mentions a rate hike or payment allocation, think CARD Act.

Open-end credit also carries billing-error rights under the Fair Credit Billing Act, woven into Reg Z. A consumer who spots a billing error, a charge they didn't make, a wrong amount, generally has sixty days from the statement to dispute it in writing, and the issuer must investigate and resolve it within defined timeframes, much like Reg E but for credit. There's also an over-limit opt-in: an issuer can't charge an over-the-limit fee unless the consumer affirmatively consented to over-limit transactions.

Notice how these opt-in patterns echo Reg E's overdraft opt-in, the regulators favor affirmative consent before fee-generating services. The exam rewards you for spotting that recurring design across rules. One more open-end nuance: there's a clear distinction between a billing error under the Fair Credit Billing Act, which is about the statement itself, and a claim-and-defense right, which lets a consumer assert against the card issuer a dispute they have with the merchant over goods or services purchased with the card, subject to certain conditions.

Both protect cardholders, but they solve different problems, so read the fact pattern for whether the complaint is about the statement or about the purchase.

Recap of open-end Truth in Lending. Reg Z, at twelve C-F-R ten twenty-six, discloses the true cost of credit. For open-end accounts, expect the Schumer box at solicitation, account-opening disclosures, periodic statements, and change-in-terms notices.

The finance charge is the dollar cost; the A-P-R is its yearly rate. And the CARD Act adds key protections: twenty-one-day grace, forty-five-day advance notice, highest-rate payment allocation, and ability-to-pay. Go test yourself, then we move to closed-end credit and mortgages, the densest piece of Reg Z.
