Notice Harbor

Terms of Service

Version 2026-07-08 · Last updated: July 8, 2026

These Terms of Service (“Terms”) are a binding agreement between you and AG Labs LLC, a New York limited liability company, doing business as Notice Harbor (“Notice Harbor,” “we,” “us,” or the “Service”), and govern your use of Notice Harbor, a service that prepares, serves, and — for mechanics liens — records California construction notices and lien documents, including preliminary notices (Cal. Civ. Code §§ 8100–8118), notices of intent to lien, and mechanics liens (Cal. Civ. Code §§ 8410–8424). By checking the acceptance box when you create an account or when prompted in the Service, or by using the Service, you agree to these Terms. Please read §16 (Dispute Resolution and Mandatory Arbitration) carefully — it requires most disputes to be resolved by binding individual arbitration and waives your right to a jury trial and to participate in a class action.

1. Not a law firm

Notice Harbor is not a law firm, is not a substitute for a law firm, and does not provide legal advice. Nothing on this site, in any notice or lien document we prepare, or in any communication from us — whether from automated tools or a member of our staff — constitutes legal advice or creates an attorney–client relationship. We do not advise you whether you have, or whether any document preserves, any lien, bond, or other right. California preliminary notice and mechanics lien rules are strict, fact-specific, and carry deadlines that, if missed, can permanently extinguish your rights. If you have any question about the law or your particular project, consult a qualified California construction attorney.

2. Eligibility and authority

You must be at least 18 years old and legally authorized to send the notice or record the lien on behalf of the claimant you represent — whether that is yourself, your company, or another party you are entitled to act for. You are solely responsible for confirming that authority. If you use the Service on behalf of a company or other entity, you represent that you are authorized to bind that entity to these Terms.

3. Your responsibility for accuracy

You provide the information used to prepare each document, including the property address, assessor’s parcel number, property owner(s), general contractor, lender, description of work, project dates, and claim amount. You are solely responsible for the accuracy of this information. A notice or lien based on incorrect, incomplete, or out-of-date information may be legally ineffective, and recording an inaccurate or exaggerated lien can expose you to statutory liability (see §8).

Our auto-fill, lookup, and verification features — including property and owner lookups drawn from third-party and public records (such as county assessor and tax data), USPS / address-deliverability checks, and any owner, general-contractor, or lender details that our staff locate, add, or research for you — are conveniences only. We do not independently verify, and we do not warrant the accuracy or completeness of, any information obtained from public records, third parties, or our own research, and we make no representation that we have identified every owner, contractor, or lender of record. You must review and confirm every field before submitting. Where we add or research a party for you, you remain responsible for confirming it is correct.

4. What we do and don’t do

We do not:

5. Limited agency authorization

By using the Service, you authorize Notice Harbor to act as your limited agent for the sole purpose of carrying out the services you request — namely, researching and verifying project and party information, preparing standard construction notice and lien documents, serving those documents by Certified Mail, and, for mechanics liens, submitting the Claim of Mechanics Lien to the county recorder on your behalf. This is a limited agency for these purposes only. It does not authorize us to give legal advice, make legal judgments for you, or act for you in any other matter, and it does not make us responsible for the accuracy of the information you provide or approve.

6. Electronic contracting, signatures, and declarations

You consent to do business electronically and to the use of electronic signatures and records. Checking a box presented with these Terms (for example, “I have read and agree to the Terms of Service and Privacy Policy”) is your electronic signature and constitutes your acceptance of these Terms, with the same legal effect as a handwritten signature under the federal ESIGN Act and the California Uniform Electronic Transactions Act. We keep a record of each acceptance — including the date, time, and the version of the Terms accepted — and you may request a copy at hello@noticeharbor.com. When you type your name and check the accompanying box on a notice or lien, you are signing that document electronically, and your electronic signature has the same legal effect as a handwritten signature under the federal ESIGN Act and the California Uniform Electronic Transactions Act. For documents that require a verification — including a Notice of Intent to Lien and a Claim of Mechanics Lien — your typed name and checkbox also constitute your declaration, under penalty of perjury under the laws of the State of California, that you have read the document, know its contents, and that the statements in it are true of your own knowledge. You are responsible for the truthfulness of every declaration you sign.

7. Deadlines and delivery

California imposes strict deadlines — for example, preliminary notices generally must be served within 20 days of first furnishing labor or materials (Cal. Civ. Code § 8204), and mechanics liens must be recorded within statutory windows tied to completion or cessation of work. You are solely responsible for knowing your deadlines and for ordering each document with enough lead time for us to prepare, serve, and (for liens) record it before your deadline.

Any turnaround time we mention — such as a goal of mailing within one business day — is a target, not a promise or guarantee. We make reasonable efforts to act promptly after you submit and pay, but we do not guarantee any preparation, mailing, or recording time, and we do not control USPS delivery timing or county recorder processing. In the event of any conflict between a turnaround estimate shown elsewhere in the Service and these Terms, these Terms control. The date shown on the Proof of Service is the date we deposit the document with USPS Certified Mail, which is the date the law treats as the date of service.

8. Mechanics liens

Recording a Claim of Mechanics Lien does not establish that the lien is valid, perfected, enforceable, or correctly stated; whether a lien is valid depends on facts and law outside our control and is for you and your attorney to determine. California law imposes penalties for recording a false, frivolous, or willfully exaggerated lien (see, e.g., Cal. Civ. Code § 8422). You are solely responsible for the amount you claim, for releasing the lien when required, and for any consequence of recording a lien you were not entitled to record. We do not provide notarization, and California does not require it for a mechanics lien verified under penalty of perjury.

9. Payments and credits

Charges are processed by Stripe and, except as stated below, must be paid before we begin work. For mechanics liens, you authorize us to charge your saved payment method, off-session, for the actual county recording fee and Certified Mail cost when we record and serve the lien. Any credits or prepaid entitlements added to your account may be redeemed toward future notices and do not expire. We do not offer refunds once a document has been mailed or recorded. If we are unable to complete a document — for example, because of missing or clearly invalid information and you do not respond to our request — we will refund or credit the corresponding charge.

10. Acceptable use

You agree not to use the Service to send or record any document that is knowingly false, fraudulent, exaggerated, harassing, or unrelated to a legitimate construction claim. We may decline or cancel any document at our discretion; if we do so before mailing or recording, we will refund or credit the charge.

11. Third-party services

The Service relies on third-party providers, including Stripe (payments), Supabase (hosting, database, authentication, storage), Vercel (application hosting), Resend (transactional email), ATTOM (property data), Lob (USPS address verification and certified-mail dispatch), Google (address autocomplete), USPS (mail delivery), and county recorders. Their availability, accuracy, and timing are outside our control, and we are not responsible for their acts, omissions, or errors.

12. Disclaimers

The Service is provided “as is” and “as available,” without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the Service or any data within it will be uninterrupted, error-free, or accurate, or that any specific notice or lien will be accepted, will be effective, or will preserve any specific legal right.

13. Assumption of risk

The Service is a self-help tool that prepares standard documents from the information you provide. It is not a substitute for the advice of a licensed attorney. You understand and accept the risks of using a non-attorney document-preparation and filing service to protect time-sensitive and legally significant rights, including the risk that a document may be ineffective, untimely, or incorrect because of information you provided, a missed deadline, or a matter of law on which you did not consult an attorney.

14. Limitation of liability

To the maximum extent permitted by law, the total liability of Notice Harbor and its owners, officers, employees, agents, and contractors for any and all claims arising from or related to the Service or these Terms is limited to the greater of (a) the amount you paid us for the specific document giving rise to the claim or (b) one hundred dollars ($100). We are not liable for any indirect, consequential, incidental, special, exemplary, or punitive damages, including lost profits, lost revenue, lost data, or lost lien, bond, or other legal rights, even if we have been advised of the possibility of such damages. This contract and these limitations are your sole and exclusive remedy. You agree not to bring any tort or other non-contract claim against Notice Harbor or any person protected by this section arising from the Service. You agree these limitations are reasonable and that, without them, we could not provide the Service at the prices charged.

15. Indemnification

You agree to defend, indemnify, and hold harmless Notice Harbor and its owners, officers, employees, agents, and contractors from any claim, loss, liability, cost, or expense (including reasonable attorneys’ fees) brought by you or any third party and arising from (a) information you provided that was inaccurate, exaggerated, or that you lacked authority to submit, (b) any document we prepared, served, or recorded based on that information, (c) your violation of these Terms, or (d) your violation of any law or the rights of any third party.

16. Dispute resolution and mandatory arbitration

Please read this section carefully. It affects your legal rights, including your right to sue in court and to participate in a class action.

Any dispute arising out of or relating to these Terms or the Service — except a claim by us to collect amounts you owe us, and except a claim that may be brought in small-claims court — shall be resolved as follows. You must first give us written notice of the dispute, with enough detail and supporting documents for us to evaluate it, at hello@noticeharbor.com. If the dispute is not resolved within thirty (30) days after we receive your notice, it shall be resolved exclusively by final and binding individual arbitration administered by the American Arbitration Association under its Commercial Arbitration Rules then in effect, and judgment on the award may be entered in any court of competent jurisdiction in California.

Class-action and jury waiver. All claims must be brought in your individual capacity, and not as a plaintiff or class member in any purported class, collective, consolidated, or representative proceeding. The arbitrator may not consolidate the claims of more than one person and may not preside over any form of a representative or class proceeding. You and we each waive any right to a jury trial. If the class-action waiver in this section is found unenforceable as to any claim, that claim (and only that claim) shall be severed and proceed in court, while all other claims remain in arbitration.

30-day opt-out. You may opt out of this arbitration and class-waiver section by emailing hello@noticeharbor.com with your account email and a statement that you opt out, within 30 days of first accepting these Terms. Opting out does not affect any other part of these Terms.

17. Attorneys’ fees

In any dispute, arbitration, or proceeding arising out of or relating to these Terms or the Service, the prevailing party is entitled to recover its reasonable costs, expenses, and attorneys’ fees, to the extent permitted by law.

18. Governing law and venue

These Terms are governed by the laws of the State of California, without regard to conflict-of-law rules. Subject to §16, any dispute not subject to arbitration will be resolved exclusively in the state or federal courts located in California, and you consent to their jurisdiction and venue.

19. No third-party beneficiaries

These Terms are for the sole benefit of you and Notice Harbor and our respective successors and permitted assigns. Nothing in these Terms, express or implied, confers on any other person or entity — including any property owner, general contractor, lender, or other recipient named in a document — any legal or equitable right, benefit, or remedy of any kind.

20. Entire agreement; modification

These Terms are the entire agreement between you and Notice Harbor about the Service and supersede all prior agreements and representations. No promise or representation outside these Terms is binding. We may update these Terms as described in §24; otherwise, they may be amended only in a writing we issue or agree to, and not orally or by conduct.

21. Severability

If any provision of these Terms is held unenforceable, it will be reformed only to the extent necessary to make it enforceable, or, if it cannot be reformed, severed, and the remaining provisions will remain in full force and effect.

22. Construction

You had the opportunity to review these Terms and to consult counsel. The rule that ambiguities are construed against the drafter does not apply to these Terms.

23. Termination

You may stop using the Service and delete your account at any time. We may suspend or terminate accounts that violate these Terms. Sections that by their nature should survive termination — including §§ 3, 6, 8, and 12–22 — survive.

24. Changes

We may update these Terms from time to time. If we make material changes, we will notify users by email and update the “Last updated” date above. For material changes we may also require you to accept the updated Terms before continuing to use the Service; the version identifier above changes with each update. Continued use of the Service after changes take effect constitutes acceptance of the new Terms.
