The fast answer
You have the full contract in front of you. This page gives you the fast triage: which terms are normal, which need a written answer before signing, and which are genuine stop signs. The 9 flags below are the terms most likely to cause buyer regret — not because they're rare, but because they're rarely explained clearly before signing.
Key takeaways
This is not a comprehensive contract guide — it is a fast warning check for the terms most likely to cause buyer regret. For full clause-by-clause verification, use the how to read a home security contract guide → after clearing these stop signs.
NORMAL
This term is standard. Understand it, document it, and proceed if comfortable.
NEEDS CLARIFICATION
Get a written answer to the specific question before signing. Verbal clarification is not sufficient.
STOP SIGN
Do not sign until this term is corrected in writing. Proceeding locks in the risk.

1. ETF formula charges more than 75% of remaining balance
STOP SIGNWhat it looks like in the contract
The early termination section states a percentage above 75%, or a flat-dollar amount that — when calculated against your remaining term — exceeds 75% of remaining payments.
What it means
ADT's standard professionally installed contract ETF is approximately 75% of remaining monitoring balance. Any formula that results in a higher charge — 80%, 90%, or 100% of remaining balance — is above market. Some dealer-originated contracts use flat ETF amounts (e.g., '$850 regardless of cancellation date') that can significantly exceed the standard percentage calculation. Always calculate your worst-case ETF from both the formula and any flat amount before signing.
What to do
Ask the rep to confirm the exact formula and a worked example: 'If I cancel at month 12 and month 24, what is my exact ETF in dollars?' If the result exceeds 75% of remaining monthly payments, negotiate or walk away. Do not accept 'it's standard' without seeing the calculation.
2. Rate escalation clause with no ceiling, or ceiling above 10%
STOP SIGNWhat it looks like in the contract
The monitoring fee section includes language like 'may increase annually' or 'subject to adjustment' without specifying a maximum percentage. Or the cap is stated but is unusually high — above 10%.
What it means
A rate escalation clause with no ceiling gives the company unlimited flexibility to raise your rate at any time. Most legitimate contracts cap annual increases at 3–7%. A 10%+ cap on a 36-month contract at $52.99/month starting rate could push your bill to $70+/month by year 3. The clause with no ceiling is almost never disclosed verbally and creates significant total-cost exposure buyers don't anticipate.
What to do
Find the rate escalation section. Confirm the ceiling percentage is specified. If the ceiling is absent or above 10%, ask for a written rate cap or rate-lock addendum before signing. Calculate total cost at the maximum allowed rate — not just the starting rate.
3. "No ETF" or "no contract" language alongside a separate financing exhibit
STOP SIGNWhat it looks like in the contract
The main monitoring agreement says 'no early termination fee' or 'no contract' — but there is also a separate document titled 'SmartPay Agreement,' 'Citizens Pay,' 'Equipment Financing Terms,' or similar.
What it means
This is the most common structural trap in Vivint contracts and some other provider offers. Vivint's monitoring agreement genuinely has no ETF — but the Citizens Pay equipment loan is a real consumer installment loan that continues on schedule regardless of monitoring status. 'No monitoring contract' does not mean 'no financial obligation.' Canceling monitoring stops dispatch and app access; it does not stop equipment loan payments. Missing loan payments damages credit and triggers collections.
What to do
If any financing exhibit exists alongside 'no contract' monitoring language: read the financing exhibit in full. Calculate the remaining loan balance at every point in the term. Treat the loan payoff amount as your effective ETF equivalent. Do not assume 'no monitoring contract' means you can walk away with no financial consequence.
4. ETF calculated on full contract value, not remaining balance
STOP SIGNWhat it looks like in the contract
The ETF clause states a fixed dollar amount equal to 100% of the remaining contract value — not a declining percentage as months pass.
What it means
Some dealer-originated contracts use a flat ETF that is effectively 100% of remaining payments, rather than the declining 75%-of-remaining-balance formula. This means your ETF doesn't decline meaningfully as you pay down the contract. A buyer at month 20 of a 36-month contract pays almost as much to exit as they did at month 1. This is materially worse than the 75% standard and is not always disclosed.
What to do
Calculate your ETF at three points: month 6, month 18, and month 30. If the ETF does not decline meaningfully as months pass, the formula is not percentage-of-remaining. Ask for clarification in writing. If the company confirms it is a flat amount, negotiate for a declining-balance formula or factor this into your signing decision.
5. Auto-renewal notice window longer than 60 days
NEEDS CLARIFICATIONWhat it looks like in the contract
The cancellation or auto-renewal section requires written cancellation notice 61–90 days (or more) before the contract end date to prevent renewal.
What it means
Standard auto-renewal notice windows are 30–60 days. A 90-day notice window means you must decide to cancel three months before your contract ends — well before most buyers begin thinking about renewal. Missing this window typically locks you into another full term with a new ETF cycle. Windows longer than 60 days are above market and create meaningful auto-lock-in risk.
What to do
Find the auto-renewal or cancellation section. Note the exact notice period and required method (written notice, certified mail, online portal). Set a calendar reminder for 30 days before the notice deadline — not the contract end date itself. If the window is 90+ days, ask whether it can be shortened to 60 days in writing.
6. Contract counter-party is a dealer, not the brand
NEEDS CLARIFICATIONWhat it looks like in the contract
The contract header identifies the 'Service Provider' or 'Company' as a third-party entity — 'ABC Security LLC,' 'XYZ Protection Inc.' — rather than ADT Inc., Vivint Smart Home Inc., or another brand entity directly.
What it means
A dealer contract is legally valid but your dispute rights, service escalation path, and contract terms may differ from the brand's published defaults. Dealer-originated ADT contracts can carry higher ETFs, different rate escalation ceilings, and different equipment terms than ADT's direct-to-consumer agreements. Your escalation path leads to the dealer — not ADT or Vivint corporate — unless brand-level escalation is explicitly preserved.
What to do
Ask: 'Is this agreement with [Brand] directly, or with an authorized dealer?' Get the legal entity name in writing. Confirm what happens if you need to escalate a dispute beyond the dealer. Compare the specific contract terms against what the brand publishes directly, particularly the ETF formula and rate escalation ceiling.
7. Assignment clause allows contract transfer without buyer consent
NEEDS CLARIFICATIONWhat it looks like in the contract
The assignment section says the company may 'assign this agreement to any third party without prior notice' or 'without the customer's consent.'
What it means
Assignment clauses are standard in most home security contracts — the company needs to be able to sell or merge without renegotiating every customer agreement. However, clauses that allow transfer without any notice are unusually broad. If the monitoring company is acquired (which happens frequently in home security), your contract may transfer to a new entity with different service standards, without your knowledge.
What to do
Find the assignment section. Note whether notice is required and what your options are if the contract is assigned. Ask: 'If this company is acquired, does my rate and contract term remain unchanged?' A legitimate answer should confirm term protection even through assignment.
8. Mandatory arbitration clause that eliminates class action rights
NEEDS CLARIFICATIONWhat it looks like in the contract
A dispute resolution section (sometimes labeled 'Arbitration,' 'Mandatory Arbitration,' or buried in 'Legal Remedies') states that you waive the right to join a class action and must resolve disputes individually through binding arbitration.
What it means
Mandatory arbitration clauses are common in home security contracts and are broadly legal. The practical effect: if the company applies a billing error, rate increase, or ETF calculation you believe is wrong, you cannot join a class action lawsuit. You must individually pursue arbitration, which is typically more expensive and less accessible for individual consumers. This is not automatically disqualifying, but it changes your recourse if something goes wrong.
What to do
Locate the arbitration clause. Note whether it includes a small-claims court carve-out (most do). Note any opt-out provisions — some arbitration clauses allow a 30-day written opt-out. If an opt-out exists, exercise it in writing before the window closes.
9. Equipment financing buried in a separate exhibit with no main-body summary
NEEDS CLARIFICATIONWhat it looks like in the contract
The main service agreement contains no mention of equipment financing, but there is a second document — an addendum, exhibit, or 'Equipment Financing Agreement' — containing loan terms. The monthly payment on the main agreement doesn't break out monitoring vs. financing.
What it means
Many buyers sign two separate agreements without realizing the second is a standalone consumer loan. The monthly payment in the main contract may show a single number without clarifying the monitoring-vs.-financing split. When you later try to cancel monitoring, you discover the loan continues independently — and the loan balance you weren't tracking is still due in full.
What to do
If any secondary exhibit exists: read it fully. Identify the loan term, APR, total financed amount, payoff schedule, and what happens to the loan if monitoring is canceled. Ask for a written summary of both obligations — monitoring and financing — in a single document. Treat any secondary financing document as its own financial obligation.
NORMAL — understand and proceed
A NORMAL term is standard in the industry. It's not a reason to stop — but it is a reason to document. For every NORMAL clause: note the specific term, the specific percentage or amount, and any deadline. These are the numbers you'll need if a billing dispute or cancellation arises later.
Practical step: Screenshot or photograph every page of the signed contract. Store it where you can retrieve it in 18 months — not just in a email thread you'll have to search for.
NEEDS CLARIFICATION — get a written answer before signing
A NEEDS CLARIFICATION term is not automatically disqualifying. But the specific question it raises must be answered in writing — not verbally — before you sign. If the rep answers verbally but cannot produce a written addendum, treat that reluctance as a signal about whether the answer will hold post-signing.
Practical step: Write down the exact question the clause raised. Ask the rep to show you the contract clause that addresses it. If no clause exists, ask for a written addendum. Get the addendum before the installation appointment.
STOP SIGN — do not sign until corrected in writing
A STOP SIGN term creates meaningful financial risk or removes meaningful buyer protections. Do not sign a contract with an unresolved STOP SIGN term. Once you sign, the risk is locked in. Correction requires a written addendum modifying the specific clause. Verbal assurances do not count. If the company refuses to correct a STOP SIGN term in writing, that is complete information: they intend to enforce it as written.
Practical step: Identify the exact clause by section number. Ask for a specific written modification. If refused, decide whether this is a walk-away trigger — or factor the known risk into your signing decision explicitly.
ADT: what to specifically watch for
Vivint: the "no contract" financing trap
Vivint monitoring genuinely has no ETF and no monitoring contract. But most Vivint installations involve a Citizens Pay equipment loan, which is a multi-year consumer installment loan for the hardware — and it is a contract.
The contract governs. What the rep said does not.
If the contract says something different from what the rep told you — a different term length, a different ETF amount, a rate escalation clause that contradicts a "locked rate" promise — do not sign until the discrepancy is resolved in writing.
