Notice Harbor

Terms of Service

Last updated: April 18, 2026

These Terms of Service (“Terms”) govern your use of Notice Harbor (“we,” “us,” or the “Service”), a service that prepares and mails California preliminary notices under Cal. Civ. Code §§ 8100–8118. By creating an account or using the Service, you agree to these Terms.

1. Not a law firm

Notice Harbor is not a law firm and does not provide legal advice. Nothing on this site, in any notice we prepare, or in any communication from us constitutes legal advice or creates an attorney–client relationship. California preliminary notice rules are strict and fact-specific. If you are uncertain whether you have lien or bond rights, consult an attorney.

2. Eligibility

You must be at least 18 years old and legally authorized to send preliminary notices 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.

3. Your responsibility for accuracy

You provide the information used to prepare each notice, including the property address, assessor’s parcel number, property owner, general contractor, lender, description of work, project dates, and claim amount. We do not independently verify this information. You are solely responsible for its accuracy, and a notice based on incorrect information may be legally ineffective.

Our auto-fill and verification features (property lookup, USPS address verification, county assessor links) are conveniences only. You must review and confirm every field before submitting.

4. What we do and don’t do

We:

We do not:

5. Deadlines and delivery

California generally requires preliminary notices to be served within 20 days of first furnishing labor or materials (Cal. Civ. Code § 8204). You are responsible for ordering your notice in time for us to prepare and mail it before your deadline.

We make reasonable efforts to mail notices promptly after submission, but we do not guarantee same-day mailing, and we do not control USPS delivery timing. The date shown on the Proof of Service is the date we deposit the notice with USPS Certified Mail, which is the date the law treats as the date of service.

6. Payments and credits

Purchases are one-time charges processed by Stripe. Credits added to your account may be redeemed toward future notices and do not expire. We do not offer refunds once a notice has been mailed. If we are unable to process a notice before mailing — for example, because of missing or clearly invalid information and you do not respond to our request — we will refund or credit the charge.

7. Acceptable use

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

8. 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), Smarty (USPS address verification), Google (address autocomplete), and USPS (mail delivery). Their availability and accuracy are outside our control.

9. 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, and non-infringement. We do not warrant that the Service will be uninterrupted or error-free, or that any specific notice will preserve any specific legal right.

10. Limitation of liability

To the maximum extent permitted by law, our total liability for any claim arising from or related to the Service is limited to the amount you paid us for the notice giving rise to the claim. We are not liable for indirect, consequential, incidental, special, or punitive damages, including lost profits or lost lien or bond rights.

11. Indemnification

You agree to indemnify and hold harmless Notice Harbor from any claim arising from (a) information you provided that was inaccurate or that you lacked authority to submit, (b) your violation of these Terms, or (c) your violation of any law.

12. Termination

You may stop using the Service and delete your account at any time. We may suspend or terminate accounts that violate these Terms.

13. Governing law

These Terms are governed by the laws of the State of California, without regard to conflict-of-law rules. Any dispute arising from or related to these Terms or the Service will be resolved in the state or federal courts located in California.

14. 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. Continued use of the Service after changes take effect constitutes acceptance of the new Terms.
