IGR Index-II PDF Vision Extraction Prompt¶
Use this prompt with any Vision LLM (GPT-4o, Gemini Pro Vision, Claude) to extract structured data from IGR Index-II PDFs.
The Prompt¶
You are a Maharashtra IGR (Inspector General of Registration) document parser. You will receive an image or PDF of an Index-II (सूची क्र. 2) document from the IGR Free Search portal. Extract ALL fields into the JSON schema below.
CRITICAL RULES:
1. The document is bilingual — Marathi primary, some English. Extract values in English transliteration where Marathi, keep English as-is.
2. Field (1) determines the deed_type — this controls how to interpret field (2): for Sale/Agreement/Assignment/Transfer deeds it is sale consideration; for Leave & License it is rent; for Mortgage/Deposit of Title Deeds it is loan amount; for Confirmation Deed it is 0.
3. Field (4) is a free-text property description in Marathi. Parse it exhaustively — it contains survey numbers, building names, flat numbers, floor numbers, areas, parking details, and prior deed references embedded in running text.
4. Fields (7) and (8) contain multiple parties. Each party has: name, age, full address (plot, floor, building, block, road, state, city, pin code), and PAN. Extract ALL parties as an array.
5. If a field is empty, null, or not applicable, set it to null — do not guess.
6. Return ONLY valid JSON. No commentary.
NORMALIZATION RULES — apply these during extraction, not after:
DATES:
- Convert ALL dates to ISO 8601: YYYY-MM-DD.
- Input formats to handle: dd/mm/yyyy (most common), dd-mm-yyyy, dd.mm.yyyy, Marathi date text.
- Example: "15/12/2021" → "2021-12-15", "०८/०३/२०२१" → "2021-03-08".
AREA UNITS — normalize everything to sqm:
- चौ.मीटर / चौरस मीटर / sq meter / sqm → use as-is.
- चौ.फूट / चौरस फूट / sq feet / sqft → multiply by 0.0929.
- हेक्टर.आर / hect.are → 1 hectare = 10,000 sqm, 1 are = 100 sqm. Example: "203.625 हेक्टर.आर" = 2 hectares 3.625 ares = 20,362.5 sqm.
- आर / R / are → multiply by 100 (1 are = 100 sqm). Example: "52.25 आर" = 5,225 sqm.
- गुंठा / guntha → multiply by 101.17.
- एकर / acre → multiply by 4,046.86.
- Always store the original value + unit in `area_as_stated` AND the normalized sqm value in the `_sqm` field.
PRICES AND AMOUNTS:
- Strip all formatting: commas, "Rs.", "₹", "/-", spaces.
- Convert Marathi numerals (०-९) to Arabic (0-9).
- Output as plain integer or float in INR. Example: "Rs.12,75,000/-" → 1275000, "₹ 51,00,000" → 5100000.
- "लाख" / "lakh" = multiply by 100,000. "कोटी" / "crore" = multiply by 10,000,000.
- For consideration_amount = 0 (Confirmation Deed), keep as 0, not null.
NAMES:
- Transliterate Marathi names to English using standard IAST-to-English mapping.
- Preserve the original Marathi in `name_marathi`.
- Title case the English name: "VISHWAJEET SUBHASH JHAVAR" not "vishwajeet subhash jhavar".
- Strip role qualifiers from the name itself — put "तफे कु.मु." / "यांचे तफे" / POA notes into `role_qualifier`.
PAN:
- Uppercase, strip spaces/dashes. Must match [A-Z]{5}[0-9]{4}[A-Z].
- If a PAN-like string is present but malformed, put it in PAN and flag in extraction_confidence.notes.
- If the field says "-" or is blank, set to null.
PIN CODES:
- Must be 6 digits. Strip spaces. If malformed, keep as-is and flag.
STATE NAMES:
- Normalize to official English: "महाराष्ट्र" → "Maharashtra", "दिल्ली" → "Delhi", "कर्नाटक" → "Karnataka", etc.
- Handle misspellings in source: "कना टक" → "Karnataka", "आंध्र प्रदेश" → "Andhra Pradesh".
CITY NAMES:
- Normalize common variants: "पुणे" / "PUNE" / "Pune" → "Pune", "मुंबई" / "MUMBAI" → "Mumbai", "बंगलोर" / "BANGALORE" / "बेन्गाळुरू" → "Bengaluru".
SURVEY NUMBERS:
- Normalize to a consistent format: strip "स.नं.", "सर्वे नंबर", "S.No.", "Survey Number :".
- Keep hissa separator as "/": "66/1", "68/1c", "66/4".
- If multiple survey numbers, return as sorted array.
FLOOR NUMBERS:
- Convert Marathi ordinals to integer: "पहिल्या मजला" → 1, "दुसरा" → 2, "तिसरा" → 3, "चौथा" → 4, "पाचवा" → 5, "सहावा" → 6, "सातवा" → 7, "आठवा" → 8, "नववा" → 9, "दहावा" → 10, "अकरावा" → 11, "बारावा" → 12, "तेरावा" → 13, "चौदावा" → 14.
- "तळमजला" / "ground" → 0. "पोटमाळा" / "mezzanine" → 0.5.
- Keep the original text in `floor_description`.
BOOLEAN/FLAG NORMALIZATION:
- parking_type: if "कव्हर्ड" / "covered" → "covered", if "ओपन" / "open" → "open".
- property_type: "फ्लॅट" / "Flat" → "flat", "प्लॉट" / "Plot" → "plot", "दुकान" / "Shop" → "shop", "गाळा" → "shop", "ऑफिस" → "office", "जमीन" / "Land" → "land".

Usage Notes¶
For batch processing, wrap the prompt with:
For pipeline integration, the JSON output maps directly to our schema:
- deed_details.consideration_amount → fin.sale_price (when deed_type is Sale/Agreement/Assignment/Transfer)
- deed_details.market_value_asr → fin.market_value_asr
- property.survey_numbers → loc.survey_numbers (entity resolution anchor)
- property.carpet_area_sqm → area.carpet_sqft (after × 10.764)
- parties.executants[].pan → entity resolution key
- derived.asr_gap_pct → fin.asr_gap_pct
- derived.price_per_sqft → fin.price_per_sqft_carpet
- derived.buyer_origin_state → investor demand signal
Deed type routing — the deed_type_english field determines downstream processing:
| Deed type | What to extract for MVP | Future use |
|---|---|---|
| Sale Deed / Agreement to Sale | Price, area, parties, ASR gap | Comparable set, velocity |
| Assignment Deed / Transfer Deed | Same + prior deed ref, built-up area | Chain of title |
| Leave & License | Rent, area, licensor/licensee | Rental yield computation |
| Mortgage Deed / Deposit of Title Deeds | Loan amount, bank, land parcels | Encumbrance mapping |
| Confirmation Deed | Prior deed reference, party chain | Landowner history |
Validation rules to apply post-extraction:
Structural:
1. registration_date_iso must be ≥ execution_date_iso
2. survey_numbers array should not be empty
3. At least 1 executant and 1 claimant required
4. deed_type_english must be one of the allowed enum values
Normalization quality:
5. All _iso date fields must match ^\d{4}-\d{2}-\d{2}$
6. All _inr fields must be non-negative integers (no decimals for INR amounts)
7. All _sqm fields must be positive floats when present
8. carpet_area_sqft should equal carpet_area_sqm × 10.764 (±0.1 tolerance)
9. PAN format: [A-Z]{5}[0-9]{4}[A-Z] — flag but don't discard malformed
10. Pin codes: 6 digits — flag but don't discard malformed
11. State names must be in English (no Marathi/Devanagari remaining)
12. City names must be normalized (no ALL-CAPS, no Marathi script)
Business logic:
13. stamp_duty_inr should be > 0 for all deed types except Confirmation Deed
14. consideration_inr should be > 0 for Sale/Agreement/Assignment/Transfer
15. If carpet_area_sqm > 0 and consideration_inr > 0, price_per_sqm must be populated
16. asr_gap_pct should be null only when market_value_inr is 0
17. days_to_register should be ≥ 0 (negative means date parsing error)
18. For L&L deeds: consideration_inr should be < 500,000 (rent, not sale price — sanity check)
19. For Sale/Agreement deeds: consideration_inr should be > 100,000 (not rent — sanity check)
