Is Michael J. Adams, P.C. legit -- and how should I handle them?

Yes -- Michael J. Adams, P.C. is a legitimate, active debt-collection law firm based in San Antonio, Texas, not a scam. It is a creditors'-rights firm: it represents original creditors, debt buyers, and collection agencies, and the way a collection law firm collects is by filing lawsuits against consumers and, after a judgment, pursuing garnishment, levy, and other post-judgment remedies. That means the single biggest risk here is a court citation and petition, not just a phone call -- so the reassuring flip side of "it's legit" is that you should act on your rights rather than ignore it, because a law firm can actually sue and get a judgment. Here is the key legal point: an attorney or law firm that regularly collects consumer debts is still a "debt collector" under the federal Fair Debt Collection Practices Act (FDCPA) -- lawyers are not exempt -- so you keep every consumer protection. Send a written validation request within 30 days demanding the amount and the original creditor, and don't admit the debt or promise to pay on a call. Confirm what kind of account this is: an unsecured consumer credit-card or personal-loan balance is negotiable and settle-able, so make sure you're dealing with that kind of debt before you make any plan. If the plaintiff is a debt buyer rather than your original creditor -- collection firms often file for buyers -- demand the chain of title: the bill of sale, the assignment, and account-level records proving that entity owns YOUR specific account and that the balance is correct. Check the statute of limitations, because an old account may already be time-barred -- Texas generally allows four years to sue on most unsecured accounts, and remember a single payment or a written promise to pay can restart the clock, so don't reset a time-barred debt by accident; if it's too old to sue on, raise a time-barred defense. Above all, if you're served in Texas, never ignore the citation: file a written answer by the deadline, because a default judgment is what enables wage garnishment, a bank levy, or a lien. A genuinely-owed unsecured balance, once validated and within the statute of limitations, can often be settled in writing -- get any agreement in writing before you pay, and note that a forgiven balance over $600 can trigger a 1099-C. Finally, watch for impostor red flags: anyone demanding payment by gift cards, wire, or crypto, or threatening arrest, is running a scam and is not this firm.
