Construction Lien Attorneys in Ontario, California

Mechanic’s and Materialmen’s Liens are the best way for subcontractors and material suppliers in Ontario, California, to secure payment. At The Cromeens Law Firm, we have a 90% success rate in collections before foreclosure becomes necessary, saving you from expensive legal fees.

Don’t Let California’s Complex Lien Laws Cost You Thousands

Every month in California, contractors and subcontractors lose $75,000+ payments, not because the work wasn’t done or the materials weren’t delivered, but because they failed to navigate California’s labyrinthine lien requirements. Miss a preliminary notice deadline, serve the wrong party, or file in the wrong timeframe, and California courts will dismiss your claim without considering its merits.

In California, there are no do-overs. One missed step means walking away from everything you’re owed.

At The Cromeens Law Firm, we help Ontario construction professionals navigate California’s complex lien maze with a proven 90% success rate in collections before foreclosure becomes necessary.

What Is a Mechanic’s and Materialmen’s Lien?

A mechanic’s lien is a legal claim you file against a property when you haven’t been paid for work or materials provided. In California, it can:

  • Block property sales or refinancing until you’re paid
  • Create powerful leverage in payment negotiations
  • Preserve your legal right to file a foreclosure lawsuit
  • Work alongside stop payment notices to freeze funds immediately

However, California lien law is among the nation’s most complex laws. If your preliminary notice is late, your lien names the wrong parties, or you miss California’s unique procedural requirements, it can be thrown out, no matter how much you’re owed.

California Mechanics Lien Deadlines: Multiple Traps, No Second Chances

California’s deadlines vary by project type and create multiple opportunities for costly mistakes:

Private Projects: 90 days after completion of work
Private Projects with Notice of Completion: 60 days after notice is recorded
Public Projects: 90 days after completion
Preliminary Notices: Must be served within 20 days of first providing labor/materials
Stop Payment Notices: Can be filed anytime before the final payment
Lien Enforcement: 90 days from recording to file foreclosure

Missing any of these deadlines invalidates your lien rights, regardless of how strong your payment claim is.

Why California Liens Fail (And How We Prevent It)

Most invalid liens fail due to California’s technical complexity:

  • Missing preliminary notices – Required on virtually all projects, regardless of size
  • Wrong service parties – California requires service on multiple parties with specific procedures
  • Incorrect property descriptions – San Bernardino County records can be complex
  • Improper timing – Multiple overlapping deadlines create confusion
  • Missing stop payment notice opportunities – Failing to use California’s unique collection tools

We don’t let that happen. Our attorneys personally verify every detail and handle all filings with San Bernardino County courts and the recorder’s offices.

Why California Lien Law Is Uniquely Challenging

California has the most complex lien system in the nation, governed by Civil Code Sections 8000-8484, making it particularly unforgiving for construction professionals:

Mandatory Preliminary Notices: Unlike most states, California requires preliminary notices on virtually all projects, regardless of contract amount. These must be served within 20 days of first providing labor or materials, with no exceptions.

Multiple Deadline Scenarios: California’s completion dates vary dramatically based on whether a Notice of Completion is filed, creating confusion about which deadline applies to your specific project.

Complex Service Requirements: California requires service on property owners, general contractors, and construction lenders using specific procedures that go far beyond simple mailing.

Dual Collection Systems: California offers both traditional liens and stop payment notices, but using them incorrectly can actually harm your collection efforts.

Stop Payment Notice Complications: While powerful, stop payment notices have their own service requirements, timing rules, and procedural traps that can invalidate them if not handled properly.

San Bernardino County Specific Issues: Rapid development in the Ontario area creates frequent property ownership changes and subdivision updates that can render lien descriptions invalid.

These technical landmines make California one of the most challenging states for DIY lien filing, which is why experienced legal representation isn’t just helpful, it’s essential for protecting your payment rights.

What a Properly Filed Lien Does For You

A valid California lien becomes your strongest collection tool:

  • Block property sales or refinancing until you’re paid
  • Force faster negotiations with general contractors or owners
  • Establish payment priority over other creditors
  • Provide legal grounds to foreclose if needed
  • Work with stop payment notices to freeze funds immediately
