Extract data from mechanics liens

A mechanics lien is a claim a contractor, subcontractor, or supplier records against a property when it has not been paid for work or materials that went into improving it. The lien attaches to the real estate itself, which is what gives an unpaid tradesperson a strong hand: the owner usually cannot sell or refinance cleanly until the claim is released. It is the counterpart of a lien waiver, the document a payee signs to give up that claim once paid. General contractors, title companies, and construction lenders all track liens because an unreleased one clouds title. Cornerstone Framing LLC recorded a lien on 2026-06-12 in Denver County, Colorado, against Highland Development Partners for unpaid framing work on the Larkspur Terrace Phase 2 project at 88 Larkspur Avenue. The claim totals 148,500 USD: a work_items table of labor totaling 88,500 USD and a materials_supplied table of lumber and fasteners totaling 60,000 USD. Of that, 40,000 USD has been paid, leaving a balance due of 108,500 USD, which reconciles to the total less the payment. The general contractor is Meridian Builders Inc., a notice of non-payment was served on 2026-04-30, and the claim is made under the Colorado mechanics lien statute (C.R.S. 38-22). Talonic reads the lien and returns the lienor, the property owner, the property description, the total claimed, the amount paid, and the balance due as fields, with the work items, the materials supplied, and the payment history as tables. The balance due is checked against the total less payments, so a filing that claims 148,500 USD and 40,000 USD paid but states a balance other than 108,500 USD is flagged. It captures the claim as recorded and makes no judgment about whether the lien is valid, perfected, or enforceable; those are questions for counsel and the recording jurisdiction.

What gets extracted from mechanics liens

How extraction works for mechanics liens

Mechanics liens are recorded on jurisdiction-specific forms and vary by state, so the lienor, the claimed amount, and the property description sit in different places from one county to the next. Talonic classifies the filing and aligns it to the lien schema in the Field Registry, so lienor.name, property_owner.name, total_amount, amount_paid, and balance_due each resolve to a field, while the work_items and payment_history tables load per row with amounts typed as numbers in USD. The 2026-06-12 filing date and the 2026-04-30 notice date parse to ISO 8601, and the lien_type and payment_status enums are preserved. Every value carries a confidence score and a source-region pointer under DIN SPEC 91491, so a title officer can verify the 108,500 USD balance against the recorded claim. Talonic reports the lien as filed and makes no validity or perfection judgment.
