Proofle reviews ALTA/NSPS land title surveys against the complete 2026 ALTA/NSPS Minimum Standard Detail Requirements — an 86-item checklist covering certification, boundary, streets, notes, encroachments, and all Table A items in scope.

When a title commitment is provided, Proofle cross-references Schedule B exceptions, checks the legal description against the commitment, and checks commitment numbers, effective dates, and certification entities against the survey — the most error-prone part of the review process. Upload a survey PDF, provide project metadata, and Proofle returns a structured first-pass report, usually in one to five minutes; large surveys take longer. Results are categorized as FAIL, RECOMMEND, PASS, or N/A based on scope, the same four the Civil 3D plug-in reports.

The most commonly missed items on survey drafts: certification block errors, missing surveyor email, assurance note issues, street numbers absent from the drawing face, and Schedule B items listed without a required disposition. Proofle checks all of these on every submission — consistently, regardless of surveyor or office.

Proofle flags for your review missing certification entities, Schedule B deficiencies, drawing-face labeling issues, and title commitment cross-reference failures. The review methodology is proprietary, developed from real production survey corrections, and continuously validated against a reviewer-adjudicated benchmark dataset.

Proofle's evaluation methodology was built from actual correction findings made by experienced human reviewers on real production surveys dating back to 2004 — the specific, documented reasons surveys failed review. That record exists only because a working commercial due-diligence firm, in business since 2003, adjudicated real surveys, item by item.

The failure-pattern expertise that record encodes — which requirements are routinely misunderstood, which vary by state, which are most likely to be wrong on a draft, and what correct looks like across thousands of real examples — is largely independent of any single standard revision; surveys fail for the same human reasons year over year. Proofle applies that expertise against the current 2026 ALTA/NSPS Minimum Standard Detail Requirements.

The methodology is continuously validated against our reviewer-adjudicated benchmark dataset and refined as the standard and review practice evolve. It doesn't stand still.

Proofle is a professional aid, not a replacement for licensed surveyor judgment. It is designed to flag the most common survey draft deficiencies and focus reviewer attention — not to make the final determination on survey acceptability.

All findings must be verified by a qualified professional before action is taken or corrections are transmitted to the surveyor.
