You found a problem. This is the action guide.
A bad or unclear clause doesn't mean the deal is dead — but it does mean you should not sign until it is corrected in writing. This page gives you the specific steps: what to ask for, what a real written change looks like, what doesn't protect you, when to escalate, and when to walk away.

Not all written confirmations are equal. The hierarchy below determines what will actually protect you if a dispute arises after signing:
Signed addendum or amendment attached to the service agreement
A supplemental document referencing the original contract, signed by both parties, specifying the exact clause and the exact new language. This is the standard for enforceable written corrections.
Revised contract PDF with corrected terms, signed by both parties
A new version of the service agreement with the problematic clause corrected and a new signature date. Equivalent in effect to the addendum. Confirm the PDF you sign matches the version that will be on file.
Written email from an authorized company representative
Useful supporting documentation but does not modify the contract itself. A company email confirming a specific term is useful if a dispute arises — but the service agreement is what courts enforce. Treat email confirmation as supplementary, not sufficient on its own.
Rep text message, verbal promise, marketing screenshot, unsigned note
None of these modify the contract. A text from the rep is not legally binding. A screenshot of the company's website is not part of your service agreement. An unsigned note from the rep is worth nothing if disputed. These forms of documentation will not protect you if the company enforces the written contract terms.
The core principle: The service agreement is the document that governs your legal obligations. Any change must be reflected in that document — either through a signed addendum or a revised contract — to be reliably enforceable.
Each item below includes: what to ask for, what the written change should actually say, and what to do if the company refuses.
1. ETF formula — from flat amount to declining-percentage formula
What to ask for
Ask the rep: 'The contract shows a flat ETF of $[amount]. I need the formula changed to reflect a declining percentage of remaining balance, consistent with your standard terms. Can you provide an addendum showing how the ETF is calculated at each month of the term?'
What the written change should say
The addendum should state: 'The Early Termination Fee is calculated as 75% of the remaining monitoring balance at the time of cancellation. Remaining balance = number of months remaining × monthly monitoring fee. Example: if 18 months remain at $[rate]/month, the ETF is 0.75 × (18 × $[rate]) = $[amount].'
If refused
If refused, the flat ETF stands as written. Calculate your maximum exposure: months remaining × rate × any applicable percentage. If the flat amount significantly exceeds 75% of remaining balance at any point in the term, treat this as a STOP SIGN unresolved. Do not sign.
2. Rate escalation ceiling — adding or capping the maximum annual increase
What to ask for
Ask: 'The rate escalation clause has no maximum percentage stated [or states X% which I find too high]. I need a written cap of [X]% annually confirmed in an addendum, or a written confirmation that my rate is locked for the full term.'
What the written change should say
The addendum should state: 'The monthly monitoring rate shall not increase by more than [X]% in any 12-month period during the original contract term. In the event of any increase, you will receive [30/60]-day written notice.' Or: 'The monthly monitoring fee of $[rate] is fixed for the duration of the original contract term and will not be subject to any rate increase.'
If refused
Calculate your worst-case 3-year total at the uncapped or high-cap rate. If the company won't cap escalation in writing, assume the maximum possible rate increase will be applied. Factor that into your comparison with no-contract alternatives. A rate escalation clause with no ceiling is a STOP SIGN.
3. Auto-renewal notice window — reducing from 90+ days to 60 days or less
What to ask for
Ask: 'The auto-renewal clause requires [90]-day advance notice. I need this reduced to 60 days in a written addendum, or I need written confirmation of the exact calendar date by which I must provide notice to prevent renewal.'
What the written change should say
The addendum should state: 'Notwithstanding Section [X] of the Service Agreement, the required cancellation notice period to prevent automatic renewal is [60] days prior to the contract end date. The contract end date is [specific calendar date]. To prevent renewal, written cancellation notice must be received by [company] no later than [date 60 days before end date].'
If refused
If the company won't reduce the notice window, note the exact deadline in your calendar immediately — 30 days before the notice deadline (not the contract end date). A 90-day notice window means you must decide to cancel three months before the contract expires. Set the reminder now, before signing.
4. Financing vs. monitoring separation — written summary of both obligations
What to ask for
Ask: 'I need a written document — either an addendum or a summary sheet signed by an authorized company representative — that states: (1) my monthly monitoring fee, (2) my monthly equipment payment, (3) the total remaining balance on the equipment loan at every year of the term, and (4) what happens to the equipment loan if I cancel monitoring.'
What the written change should say
The addendum or summary should state: 'Your monthly monitoring agreement fee is $[X]/month. This obligation ends upon cancellation of monitoring service with [required notice]. Your equipment financing obligation is $[Y]/month for [N] months through [lender name]. This obligation continues independently of monitoring status. Cancellation of monitoring does not cancel the equipment financing agreement. The remaining loan balance at any point can be calculated as [formula or schedule].'
If refused
If the company refuses to produce this summary, treat the financing exhibit as a standalone consumer loan with its own payoff schedule. Review the Citizens Pay or equipment financing agreement in isolation and calculate the full payoff at every year. Do not assume canceling monitoring ends the financing obligation.
5. Dealer vs. brand entity — confirming the legal counter-party
What to ask for
Ask: 'I need written confirmation of the full legal name of the entity I am contracting with, and confirmation of whether this entity is [Brand] directly or an authorized dealer. If this is a dealer, I need confirmation in writing of whether brand-level dispute escalation is available to me.'
What the written change should say
The addendum or written confirmation should state: 'This agreement is between [your full legal name] and [full legal name of company entity, e.g., 'XYZ Security LLC, an authorized dealer of ADT LLC']. In the event of a dispute that cannot be resolved with [dealer name], you may escalate to ADT customer relations at [contact].' Or: 'This agreement is directly with ADT LLC. No dealer intermediary is party to this agreement.'
If refused
If the company refuses to confirm the legal entity in writing, you are taking on unknown counterparty risk. Review your state's attorney general database or Better Business Bureau records for the dealer entity before signing.
6. Equipment ownership language — confirming automatic transfer at contract end
What to ask for
Ask: 'I need written confirmation that equipment ownership transfers to me automatically at the end of the service term — with no additional payment, removal charge, or reactivation fee required — and that the equipment can be used with another monitoring provider at that point.'
What the written change should say
The addendum should state: 'At the conclusion of the original service term, ownership of all installed equipment transfers automatically to [customer name] at no additional cost. No removal or reactivation fee applies. Equipment that is compatible with third-party monitoring providers may be used accordingly, subject to third-party provider requirements.'
If refused
If equipment ownership at term end requires additional action, additional payment, or is silent on compatibility, note this as a NEEDS CLARIFICATION item. Proprietary equipment that cannot be reused (Vivint is the primary example) reduces the value of 'owning' the equipment post-term — factor this into the total cost comparison.
Date
The date both parties sign the addendum — not the date of the original contract. The addendum must be dated on or before the date you sign the service agreement.
Full legal names of both parties
Your full legal name as buyer, and the company's full legal entity name (e.g., 'XYZ Security LLC' not just 'ADT'). The names must match the names on the original service agreement.
Exact clause reference by section number
The addendum must state which section of the service agreement it modifies. Example: 'This addendum modifies Section 7 (Early Termination) of the Home Security Service Agreement dated [date].' A clause with no section reference is ambiguous and harder to enforce.
Revised language verbatim
The exact new text — not a paraphrase. If the addendum says 'ETF waived in the event of a move,' that is imprecise. It should say: 'Section 7 is amended to add: The Early Termination Fee is waived if the subscriber relocates to a residence outside the provider's service area, as confirmed by the provider in writing within 30 days of relocation notice.' Precise language closes loopholes.
Signatures from both parties
Your signature and a signature from an authorized company representative — not just the sales rep (unless the rep has explicit signing authority). A manager, dealer principal, or company-designated signatory is preferable. Both signatures must appear on the same document.
Explicit reference to the original agreement
The addendum must say it applies to your specific service agreement. Example: 'This addendum is incorporated into and made part of the Home Security Service Agreement between [parties], dated [original date], and supersedes any conflicting terms in that agreement solely with respect to the provisions modified herein.'
What a weak addendum looks like — and why it won't protect you
This is what you should not accept as a written change:
Problems: no legal entity names, no section reference, no revised language verbatim, no company signature, not tied to the service agreement. This note modifies nothing. If the company later enforces the ETF, this note will not help you.
Template wording you can use to request an addendum
Send this in writing (email or text) to the rep before the installation appointment:
Before I sign, I need the following confirmed in a written addendum signed by both parties and attached to the service agreement:
[Describe the specific change — e.g., 'Section 7 (ETF) shall be amended to cap the formula at 75% of the remaining monitoring balance, calculated as a declining balance at the rate of $[X]/month.']
Please send the addendum before the installation appointment. I am not able to sign the service agreement until this is resolved in writing.
When the rep can't or won't provide a written correction, escalation is the next step — not immediate walk-away. Here are the specific triggers and the correct sequence:
Trigger
Rep refuses to provide a written addendum
Step 1: Rep → dealer manager
Ask to speak with the dealer principal or sales manager. State the specific clause at issue and that you need a written addendum before signing. Most legitimate refusals at the rep level are authority limitations, not company policy.
Trigger
Dealer manager defers back to the rep or says it's not possible
Step 2: Dealer manager → brand customer service
Call the brand's customer service line directly (ADT: 1-800-238-2727; Vivint: 1-800-216-5232). State that you are a prospective customer with a specific discrepancy between what the dealer offered and what the contract shows. Ask whether the brand can confirm the term in writing or whether the dealer's contract matches brand standards.
Trigger
Time pressure is being used to prevent you from getting written corrections
Invoke the delay right
State clearly: 'I am not able to sign today. I will review the written contract and addendum request and follow up.' Any legitimate provider will accommodate this. Time pressure that disappears when you invoke your right to delay is manufactured urgency — the promotion will still exist tomorrow.
Trigger
Dealer contract terms differ materially from what the brand advertises
Request brand confirmation before signing the dealer contract
Ask the brand's customer service line to confirm: does this dealer's contract reflect brand-standard terms? Specifically: ETF formula, rate escalation ceiling, and auto-renewal window. If the brand confirms the dealer's terms are within brand standard, proceed with that understanding. If not, you have a stronger basis for requesting corrections.
Walk away — do not sign
Escalate first, then reassess
Walk-away script
Use this verbatim if you need to disengage without confrontation:
"I'm not in a position to sign today. I'll review the written contract and my written addendum requests, and I'll follow up if I decide to move forward. Please don't proceed with any installation scheduling."
