    Answers

    Frequently Asked Questions

    Is this legally valid?
    Yes. Every notice is generated using state-specific, attorney-vetted templates that comply with exact statutory requirements (e.g., Florida Chapter 713). We map your job details directly into the required legal format and serve it via USPS Certified Mail with tracking, providing the exact Certificate of Mailing required to prove compliance in court.
    What states do you support?
    Florida, California, Arizona, Nevada, Washington, and Oregon. More coming soon.
    How is this different from hiring a lawyer?
    Attorneys charge $150–$500+ per notice. We do it for $24.99.
    What if I need more than 3 notices on Pro?
    Pro subscribers get an automatic discounted rate of $15 per additional notice.
    Can I try it before I pay?
    Yes. You can create an account and see your completed PDF before you pay. You only pay when you hit send.
    What's the difference between a notice and a demand letter?
    A preliminary notice is prevention — you file it early to protect your lien rights on a job. A demand letter is for when you're already owed: it formally demands payment, sets a deadline, and documents everything by certified mail. Notice protects the next job; demand fights for the last one.
    When should I send a demand letter instead of a notice?
    If your notice deadline has passed, or an invoice is overdue and calls aren't working, the demand letter is your tool. If you're still inside the filing window on a job, file the notice first — it's the stronger protection.
    Does LienFlash collect the debt for me?
    No. We prepare and mail your demand letter — attorney-vetted, certified, on the record. It's your letter, sent professionally. We're not a collection agency and we don't take a percentage; it's a flat $79.

    File first. Get paid.

    Protect the job you're starting, or put the overdue one on formal notice. Either way, it starts in two minutes.
