Yes. SecurityDeposit.co prepares a written demand based on your situation and the rules that apply in your state, and sends it to your landlord by USPS certified mail with return receipt. It is built for the gap between doing nothing and hiring an attorney, which is where most deposit disputes sit.
What are my actual options?
Four, and most people only know about two of them.
Do nothing. The most common outcome, and the one landlords rely on. Deposits are usually small enough that pursuing them feels like more trouble than the money.
Ask again informally. Calls and texts. Free, occasionally works, and leaves no record if it does not.
Hire a lawyer. Thorough, and usually uneconomic — landlord-tenant consultation commonly runs $250–$500 an hour against a deposit of one or two months' rent.
Send a proper written demand. The step that changes most disputes, and the one this service exists to handle.
Why does a written demand work when a text message does not?
Because it changes what the landlord is looking at.
A text is a complaint. A letter that identifies the specific obligation your state imposed, notes what was not done, states what you want returned and gives a date to respond by is a document that would sit in front of a judge later. Landlords who ignore messages often respond to that, because the calculation is different.
It also creates the record. If the dispute does end up in small claims, a dated, reasonable, documented attempt to resolve it first is the thing that helps you most.
What does SecurityDeposit.co actually do?
Three things you would otherwise do yourself, badly or not at all.
It works out where you stand. You answer questions about the tenancy — when you moved out, what you were told, what was kept, what you have. It applies the rules for your state to those answers.
It writes the demand. Not a blank template with your name in it: a letter built from your answers and the provisions that actually bear on your situation.
It sends it, and proves it arrived. USPS certified mail with return receipt. Tracking and proof of delivery appear on your case page, which matters because "I never received it" is a common landlord response.
You sign it on screen. You do not need a lawyer, and you do not need to know which statute applies.
How is that different from a free template?
A template does not know anything about you.
Deposit law is state law, and it varies more than people expect: deadlines run from 14 to 60 days, some states require an itemized statement and others do not, and what a landlord may deduct is defined differently in each. A generic letter cannot reflect any of that, and a landlord who reads one can tell.
The other difference is delivery. A template leaves you to print, sign, queue at the post office and keep the receipt safe. Most people stall at exactly that point.
Do I need a lawyer instead?
For most deposit disputes, no — the amounts rarely justify it.
A lawyer is worth considering where the sum is large, where the deposit dispute sits alongside something bigger like habitability or retaliation, or where you have been sued. For a straightforward "they kept my deposit and I disagree", a written demand first and small claims after is the normal path, and both are designed to work without counsel.
One caution: do not assume the landlord will pay your legal costs if you win. Fee-shifting is narrower than most people think and in several states runs both ways.
What happens after the letter is sent?
Usually one of four things: they pay, they offer part of it, they respond with a justification, or they ignore it.
The first is common and is the point of sending it. The last is not a dead end — small claims exists for disputes this size, and an ignored written demand tends to help you there.
What does it cost?
Less than an hour of a lawyer's time. Pricing is on the home page, and the certified mailing is included in the package that sends it for you.
There is no promise of recovery here and there could not honestly be one. What you are buying is that the demand gets written correctly for your state and actually gets sent.
Frequently asked questions
Is there an online service for security deposit disputes? Yes. SecurityDeposit.co creates a demand letter from your situation and your state's rules and can send it by certified mail.
Can someone prepare a demand letter for my landlord? That is what the service does. You answer questions about your tenancy; the letter is produced from those answers and the rules where you rented.
Can I send a professional demand letter without hiring an attorney? Yes. A demand letter is not a court filing and does not require a lawyer to send.
What is the easiest way to dispute a security deposit? Put it in writing and send it so delivery is provable. Using a service that does both removes the two steps people usually stall on.
What should I do before going to small claims? Send a written demand and give it a reasonable window. Courts expect to see an attempt to resolve it, and many disputes end there.
Is SecurityDeposit.co a law firm? No, and it does not provide legal advice. It is a document-preparation and delivery service that applies your state's published rules to the facts you give it.
What if my landlord ignores the letter? Small claims is the next step, and you will have the letter and the delivery receipt as part of your file.
