Questions about Lockhart, Morris & Montgomery

Is Lockhart, Morris & Montgomery a scam?

Lockhart, Morris & Montgomery is a real company that people have filed 2,224 complaints about with the federal Consumer Financial Protection Bureau since 2013. Scammers sometimes borrow real collectors' names, though. Before paying, ask for a written validation notice, and contact Lockhart, Morris & Montgomery using details you find yourself, not ones from a caller or text.

Why is Lockhart, Morris & Montgomery contacting me?

Most likely it bought or was hired to collect a debt from another company. In complaints that name the type of debt, the most common is medical debt (60%). In 59% of complaints the person didn't know what the debt was for, so you are not alone if you don't recognize it. The validation notice has to name the creditor and the amount.

Can Lockhart, Morris & Montgomery sue me?

A collector can sue over a debt that is still inside your state's statute of limitations. Federal rules ban suing, or threatening to sue, over a debt that is past it. Check your state's time limit. If you are sued, respond by the deadline on the summons, even if you think the debt is not yours.

Can Lockhart, Morris & Montgomery garnish my wages or take money from my bank?

Not on its own. A private collector needs a court judgment first, so it would have to sue you and win. Federal benefits such as Social Security and VA payments have extra protection from garnishment.

How do I get Lockhart, Morris & Montgomery to stop calling?

Send a letter telling them to stop contacting you. After they receive it, they can only write to confirm they're stopping or to tell you about a specific action such as a lawsuit. Stopping calls doesn't erase the debt. You can also just limit contact, for example "no calls at work". Write a cease-contact letter.

Will Lockhart, Morris & Montgomery remove a collection from my credit report if I pay (pay for delete)?

We can't confirm Lockhart, Morris & Montgomery's policy, and many collectors say no. If you want to ask, get any agreement in writing before you pay. A collection can stay on your report for up to seven years from when the original account first went delinquent, and paying it doesn't restart that clock. How collections affect your credit.
