What is Mesne?

Mesne is title insurance production software. It reads recorded documents — deeds, mortgages, satisfactions, and others — and extracts the structured data your firm uses to produce commitments, examination memos, and policies.

The model does the mechanical work: reading the document, pulling out parties, dates, recording references, legal descriptions, and prior instrument citations. The paralegal verifies every extraction before it flows downstream. No assertion appears on a commitment without human review.

Mesne replaces the abstractor role, not the paralegal. The chain of title is a structured object in the system, the commitment renders from verified data with full provenance, and every correction is logged with timestamp and user.

Workflow

How a file moves through Mesne

1. Intake
Open a new matter and capture what you know from the engagement letter — parties, transaction type, search period.
2. Documents
Upload recorded documents from the county recorder — deeds, mortgages, satisfactions, and other instruments you pull for the file. Each upload triggers extraction in the background.
3. Review
Open each document and review the model's extraction. Edit anything the model got wrong; acknowledge values you accept. When every field is addressed, approve to commit the data into the matter.
4. Compose
As documents are approved, Mesne assembles the chain of title, identifies surviving encumbrances, and renders the ALTA commitment with Schedule A, B-I, B-II, and Exhibit A. The commitment re-renders whenever you approve a new document or correct an existing one.
5. Memo
Once the file is complete, Mesne drafts the examination memo in the firm's voice — chain narrative, encumbrances summary, issues and resolutions, summary judgment on insurability. The firm reviews and edits like any working document.

Terms

Glossary

Abstractor: A title professional who reads recorded documents and prepares the structured data the firm uses for examination. Mesne replaces this role with software.
Anchor party: The party at the center of the matter (typically the purchaser on a sale, the borrower on a refinance). Used to verify the chain ends at the right person.
Chain of title: The sequence of conveyances showing how ownership of the property moved over time. The central argument any title commitment makes.
Commitment: The ALTA-form document the firm issues before closing, identifying the proposed insured, requirements to clear, exceptions that survive, and the legal description.
Conveyance: A transfer of title from one party to another, typically via a recorded deed.
Deed: The recorded instrument that conveys title. The grantor conveys to the grantee.
Encumbrance: Any claim, lien, or restriction on the property that affects ownership rights — mortgages, easements, covenants, judgments, restrictions.
Grantor / Grantee: The party conveying (grantor) and receiving (grantee) title in a deed.
Mortgagor / Mortgagee: The borrower granting (mortgagor) and the lender receiving (mortgagee) a security interest in the property.
Recording: The act of filing an instrument with the county recorder. The instrument's book and page (or instrument number) identify it uniquely within the county.
Satisfaction: The recorded instrument releasing a mortgage once the underlying loan is paid off.
Schedule A: The portion of the commitment listing what's being insured — the proposed insured, the amount, the estate, and the current vesting.
Schedule B Part I: The portion of the commitment listing requirements that must be satisfied at or before closing.
Schedule B Part II: The portion of the commitment listing exceptions to coverage — encumbrances that survive against the property (open mortgages, easements, covenants).
Search period: The number of years backward the firm searches for recorded documents (typically 40 years for a residential examination in most Southeastern states).

FAQ

Common confusion points

Why is the Approve button disabled?: Every required field needs a value, and every REVIEW-tone field needs to be either edited or acknowledged with OK as-is. The banner above the button explains what is blocking. Required fields are marked with a REQUIRED tag in their eyebrow.
What do the confidence tones mean?: REVIEW (red ring, low confidence): Mesne is uncertain. Edit it or confirm it. VERIFY (amber): Mesne is moderately confident. Glance at it. No tone (green band, high confidence): the model is confident; accept or edit as you see fit.
Why didn't a mortgage and satisfaction link automatically?: Linkage runs at approval time. If a satisfaction was approved before its target mortgage had complete recording data, the link won't fire. Today there's no manual re-link affordance — re-approve the satisfaction once the mortgage has correct book/page to retry the match.
What is a draft?: A drafted Schedule B-II title exception — paralegal-authored prose with structured book/page references that the synthesis model proposes for review. NOT a draft of the full commitment. Each draft sits in Pending until you Approve (Promote) or Reject it; promoted drafts become exceptions on the commitment.
What do the concern kinds mean (Source uncertainty / Inference / Conflict / Convention / Pairing inference)?: Source uncertainty: a fact in the draft that the model could not fully verify against the source document — worth a glance at the source PDF. Inference: a claim the model derived rather than read verbatim — confirm it reflects the source. Conflict: language in the source that contradicts another fact in the matter, office conventions, or another cited instrument — investigate the discrepancy before approving. Convention: a stylistic or formatting choice tied to office convention — confirm the phrasing matches the firm's standard. Pairing inference: an office convention requires a companion exception to be authored separately alongside this one — author the paired exception as well.
What does "cites a document not in your uploads" mean?: The exception cites a recorded document by reference (e.g., a plat at Plat Book 84/Page 102). Uploading that document is OPTIONAL — the exception text is correct either way. If you do have the document, uploading it lets Mesne verify the citation against the image; if you don't, the exception still stands as cited and is correct as-is. This is normal title work; the label is a heads-up, not a warning.
What does "Generate drafts" do per click?: Each click runs the synthesis model once and produces ONE new draft from the focused document. The model picks the most salient exception fresh each time, so repeated clicks on the same document typically produce paraphrases of the same exception. Only click again if you expect another distinct exception in the document.
What do Pending, Promoted, and Rejected mean for a draft?: Pending: the draft is awaiting your review. Promoted: you approved it, and it now renders as an exception on the commitment. Rejected: you marked it not a real exception; it stays in the audit log with your name and timestamp but does not render on the commitment.
