Certified mail requires you to sign for it — which means it's designed to be difficult to claim you didn't receive. When it comes from a law firm, that's intentional. The sender wants legal proof you received the document. Here's what you're likely dealing with.
Why Attorneys Use Certified Mail
Certified mail creates a paper trail proving delivery. Attorneys use it when:
- They need documented proof you received a notice or demand
- A deadline is triggered by receipt (your response window starts when you sign)
- The document has legal significance that requires evidence of delivery
- They're trying to establish that you were formally put on notice
Common Documents Sent by Certified Mail from Attorneys
Demand Letter
The most common. Before filing a lawsuit, attorneys often send a demand letter — stating what their client claims you owe or must do, and giving you a deadline to respond before litigation begins. This is usually pre-lawsuit, meaning you still have time to resolve the matter.
Notice of Intent to Sue
More formal than a demand letter. Some claims — including certain consumer rights cases — require attorneys to formally notify you of an intent to sue before actually filing.
Notice of Lawsuit (Summons)
In some jurisdictions, you can be served a summons (see: what is a summons) by certified mail rather than personal service. If the document says "SUMMONS" and mentions a court case number, you've been sued and have a hard deadline to respond.
Contract Notice
A formal notice required by the terms of a contract — for example, a lease termination notice, notice of breach, or notice of default under a commercial agreement.
Insurance Claim or Coverage Denial
Insurance companies often communicate formal positions by certified mail to ensure legal documentation.
IRS or Government Agency Letter
Some government correspondence arrives certified. The IRS uses certified mail for final notices (like the CP504 or CP90), which trigger legal timelines.
What to Do Immediately
Step 1: Sign for It
Don't refuse it. Refusing certified mail doesn't make the legal process go away — it just makes you look like you're avoiding service, which courts may view unfavorably. In many cases, refusing counts as legal notice anyway.
Step 2: Read It Completely
Before doing anything else, read the entire document. Specifically identify:
- Who sent it: Which attorney or firm? On behalf of which client?
- What it says: Is it a demand? A notice? A summons?
- What they want: Money? Cessation of a behavior? An action?
- The deadline: What date must you respond by?
Step 3: Don't Respond Immediately (But Don't Ignore the Deadline)
Your first instinct may be to call the attorney and explain your side. Resist this. Anything you say can be used in litigation. Take time to understand the document before communicating.
However: Note the deadline and make sure you respond before it passes. Missing a legal deadline can forfeit your rights.
Step 4: Consult an Attorney
For anything involving a lawsuit (summons), a claim over a few thousand dollars, or any document you don't fully understand — speak to an attorney before responding. Most personal attorneys offer free or low-cost initial consultations. Legal aid organizations provide free help if you qualify by income.
Step 5: Gather Your Documentation
Whatever the claim is about, start collecting relevant records:
- Contracts or agreements
- Payment records and receipts
- Communications (emails, texts, letters)
- Photos or other evidence
What You Should Not Do
- Don't throw it away or pretend you didn't receive it
- Don't call the opposing attorney and talk freely — you're not represented; they are
- Don't post about it on social media
- Don't make payments before understanding what you're agreeing to — partial payments can sometimes imply you accept liability
- Don't miss the deadline — if you need more time, request it in writing before it passes
The Silver Lining
Getting certified mail from an attorney is stressful, but it means you're in the pre-lawsuit or early-lawsuit stage — which is when you have the most options. Cases that reach this stage settle far more often than they go to trial.
Most legal disputes are about money and can be resolved through negotiation. A good attorney on your side can often resolve a demand letter faster and cheaper than if you ignore it and let it escalate to a lawsuit.
