Contract Analysis & Compliance Checker

1. Overview

The Contract Analysis & Compliance Checker reviews two or more versions of a contract, extracts the key obligations and important dates, and compares each clause across the versions to flag any inconsistencies. The result is a concise report that the Contract Manager can use to verify compliance and manage contractual risks.

2. Business Value

Risk reduction – By automatically spotting missing or altered obligations, the organization reduces exposure to unfavorable contract changes.
Efficiency – Manual line‑by‑line comparison can take hours; this process delivers the same insight in minutes.
Compliance – Highlights dates (e.g., renewal, termination) that must be tracked, supporting timely actions.

3. Operational Context

When to run:
- When a new version of a contract is received and needs to be compared with a prior version.
- When a contract manager wants to verify that obligations and dates have been captured correctly.
Who uses it: Contract Managers, Legal Operations staff, and any stakeholder responsible for contract compliance.
How often: Every time a contract version is revised (typically 2–3 times per contract lifecycle).

4. Inputs

Name/Label	Type	Details Provided
Version A Document	PDF file	The original version of the contract (PDF).
Version B Document	PDF file	The updated version of the contract (PDF).
Version Labels (optional)	Text	Friendly name for each version (e.g., “Original – 2022‑04‑01”, “Revised – 2023‑03‑15”). If not supplied, the system will use the file names.
Clause List (optional)	List of text items	Optional list of clause headings (e.g., “Termination”, “Confidentiality”) that the reviewer wants to focus on. If omitted, all clauses will be examined.

Note: Only the files listed above are needed for a single run of this process.

5. Outputs

Name/Label	Contents	Formatting Rules
Obligations List	A table of each identified obligation with: Obligation Text, Clause Heading, Version, Reference Location (page and paragraph).	Plain‑text table; each row contains one obligation.
Important Dates List	A table of extracted dates with: Date, Event Description (e.g., “Effective Date”, “Expiration Date”), Version, Reference Location.	Dates formatted as YYYY‑MM‑DD.
Clause Consistency Report	A list of clauses that differ across versions, showing: Clause Heading, Version A Text, Version B Text, Difference Description (e.g., “Added new restriction”, “Clause removed”).	Bullet points for each discrepancy.
Summary Report	A concise, written summary (maximum 500 words) that includes:

Number of obligations extracted,
Number of dates extracted,
Number of clause differences, and
Recommendations for follow‑up (e.g., “Review Clause 4.2 – new termination notice requirement”). | Formal, professional tone; headings for each section; plain‑text (no markup). |

6. Detailed Plan & Execution Steps

Load the Documents
- Open the PDF for Version A.
- Open the PDF for Version B.
Extract Text
- For each PDF, extract the full text preserving page numbers.
Identify Obligations
- Scan each paragraph for duty‑bearing verbs (e.g., “shall”, “must”, “will be required to”).
- For each identified sentence, record: the exact sentence, its clause heading, version label, and location (page/paragraph).
Extract Dates
- Scan the entire text for date patterns (e.g., “January 5, 2024”, “2024‑01‑05”, “15/03/2024”).
- For each date, note the surrounding text that explains its meaning (e.g., “Effective Date”, “Payment Due”).
Compile Clause Texts
- Locate every clause heading (e.g., “Termination”, “Confidentiality”).
- Capture the entire text under each heading for both versions.
Compare Clauses
- For each clause heading, compare the version‑A text with the version‑B text.
- Identify differences: added/removed sentences, altered obligations, changed dates, or new language.
- Record any difference with a brief description of the change.
Create the Obligations List
- Assemble all identified obligations into the Obligations List table (Section 5).
Create the Dates List
- Assemble all extracted dates into the Important Dates List table (Section 5).
Create the Clause Consistency Report
- List each clause where a difference was found, with the text from both versions and a short explanation of the difference.
Generate the Summary Report
- Write a short narrative that (a) counts the obligations, dates, and inconsistent clauses, (b) highlights any critical changes (e.g., new penalties), and (c) suggests next steps (e.g., “review new termination notice period”).
Review and Finalise
- Verify that all tables are complete and that the summary accurately reflects the findings.
Deliver Outputs
- Provide the three tables (Obligations List, Important Dates List, Clause Consistency Report) and the Summary Report to the Contract Manager.

7. Validation & Quality Checks

Document Presence – Ensure both PDF files are accessible and readable.
Extraction Confirmation – Verify that each obligation and date includes a location reference (page and paragraph).
Date Format Check – All dates must follow the YYYY‑MM‑DD pattern; flag any unrecognizable date for manual review.
Clause Matching – Confirm that every clause heading appears in both versions; flag any missing heading as a “Missing Clause” error.
Report Consistency – The total number of obligations listed must equal the count of rows in the Obligations List.
Final Review – The Contract Manager reviews the Summary Report for accuracy; if any errors are found, they are flagged for re‑run.

8. Special Rules / Edge Cases

Missing Document – If either PDF cannot be opened, abort the process and flag for manual review; no output is generated.
Unreadable Pages – If any page cannot be read, note the page number in the Summary Report and continue with the rest of the document.
No Obligations Found – If no obligations are detected in a version, add a note “No obligations detected in Version X” and continue with dates and clause comparison.
Multiple Versions – The process can handle more than two versions. The same steps repeat for each pair of versions; the Clause Consistency Report will include a comparison column for each version.

Summary Report

Formal, professional tone

Summary of Findings – Contract Comparison (Original vs. Revised)

Obligations – 12 obligations identified across both versions. The most significant new obligation is the extended confidentiality period (5 years) introduced in the revised version.

Dates – 5 date entries identified (two effective dates, two expiration dates, and a new renewal‑notice deadline). All dates conform to YYYY‑MM‑DD format.

Clause Differences – 3 major changes identified: (a) termination notice period increased from 30 to 60 days; (b) confidentiality period extended from 3 to 5 years; (c) new force‑majeure clause added.

Recommendations – Review the extended notice period and the new force‑majeure clause with the legal team to confirm compliance with corporate policy. Update the contract register with the new expiration dates and set calendar reminders for the renewal‑notice deadline (2023‑02‑01).

Appendix A – FAQ

Q1. What if a PDF contains scanned images instead of selectable text? A: The process requires readable text. If a document is scanned, request a searchable (OCR‑processed) PDF and resubmit.

Q2. Can I compare more than two versions at once? A: Yes. Add each additional version as a separate PDF and label it accordingly. The SOP will compare each version to the first (original) version and report all differences.

Q3. How are “obligations” defined? A: Any sentence that imposes a duty, requirement, or restriction on a party (e.g., “shall”, “must”, “required to”, “will be responsible for”).

Q4. What should I do if a date is ambiguous (e.g., “the first day of the next month”)? A: Flag the date as “Unclear” in the Important Dates List and note the original text. Manual review will be required.

Q5. The Clause Consistency Report shows “No change” for some clauses—should I keep those? A: Yes. “No change” confirms that the clause text is identical across the versions, confirming consistency.

Q6. What happens if the same clause appears under different headings in the two versions? A: The process will treat them as separate headings and will still compare the text. If the content matches, the report will note “No change.”

Q7. How are duplicate obligations handled? A: If the same obligation appears in multiple clauses, each instance is listed separately with its location reference.

Q8. I need a report in a specific format (e.g., Excel). A: This SOP only produces plain‑text tables. Convert the tables to the desired format (e.g., copy into Excel) after receiving the output.

Q9. Who reviews the final output? A: The Contract Manager should verify the Summary Report and, if needed, flag any items for further legal review.

Q10. What if a clause is missing entirely in the revised version? A: The report will mark the clause as “Missing in Revised version.” This is a critical inconsistency that should be investigated.
