LienFlash handles routine preliminary notice filings the way TurboTax handles a simple W-2. But some situations still require a licensed construction attorney.

Most W-2 employees don't hire a CPA to file a simple tax return. They use software. The same logic applies to preliminary notices. If you're a subcontractor filing a standard notice on a straightforward project, you don't need to pay an attorney $150–$500 for a document that follows a statutory template. LienFlash uses attorney-vetted templates that comply with each state's exact statutory requirements, including mandatory warning text, formatting rules, and service methods. You fill in your project details, we verify the address, and we mail it via USPS Certified Mail. Total cost: $24.99. Total time: under 5 minutes.
LienFlash is not a law firm and does not provide legal advice. There are situations where hiring a licensed construction attorney is essential: (1) You need to actually file and enforce a mechanics lien in court. LienFlash handles preliminary notices only — the step that preserves your right to lien. The lien itself is a separate legal action. (2) You're involved in a payment dispute that may escalate to litigation. (3) The project has unusual complexity — multiple tiers of subcontractors, federal projects, or cross-state jurisdictional issues. (4) You've already missed your preliminary notice deadline and need legal guidance on your remaining options. In these cases, an attorney's personalized advice and courtroom representation are irreplaceable.
Consider a subcontractor who works 10 projects in a quarter. With an attorney at $200 per notice, that's $2,000 per quarter just for routine document preparation. With LienFlash at $24.99 per notice, the same 10 projects cost $249.90 — an 87% savings. The Pro plan ($49/month) makes it even cheaper for high-volume filers. The money you save on routine filings can be redirected toward legal representation for the cases that actually require it.
Florida gives you 45 days. Oregon gives you 8 business days. When you're running multiple jobs, a 3–7 day attorney turnaround can eat into a deadline that's already tight. LienFlash processes your notice in under 5 minutes and gets it into USPS Certified Mail the same day. You don't have to call an office, wait for a callback, or chase down a retainer agreement. You file from the truck and move on to the next job.
The smartest approach for most subcontractors: use LienFlash for every routine preliminary notice filing to protect your lien rights on every project. Keep a relationship with a construction attorney for the 5–10% of projects where something goes wrong and you need legal firepower. This way you're protected on 100% of your jobs without spending attorney-level money on routine paperwork.
Most services help you manage notices on jobs you're starting. We also put a formal, statute-cited demand letter in the mail for $79 when you're already owed.
