DUBAI REST KNOWLEDGE CORPUS
**Purpose:** the verified knowledge brain for the platform's REST-Intelligence chatbot. Every capability, service, fee formula, document list, and rule below is drawn from the official Dubai Land Department / RERA source (dubailand.gov.ae) or corroborated 2026 sources, and carries a source note. This is the chatbot's grounding layer — it must answer *from this corpus*, never from invention.
**Governing principle (never lose this):** REST services split into **computable** (the chatbot can own: explain, calculate, verify-guide, pre-fill) and **sovereign** (only DLD/RERA can execute: authenticated registration, signing, money movement, certificates of record). The chatbot masters both but only *performs* the computable ones; for sovereign acts it prepares everything up to the gate and hands off to the real REST/MyDLD service with a deep link. Impersonating a government function is prohibited.
**Verification stamps:** figures marked `[SRC: dld ...]` are from the official DLD service pages fetched during research. Figures marked `[SRC: 2026 corroborated]` come from multiple 2026 industry sources and should be re-verified before high-stakes use. `[VERIFY]` = confirm against live DLD before quoting to a client. Last corpus build: 2026-07-02.

PART 1 — WHAT DUBAI REST IS (the frame)
Dubai REST (Real Estate Self Transaction) is DLD's smart real-estate super-app — the authoritative platform through which owners, tenants, brokers, developers, valuators, and investors transact and enquire. `[SRC: dld dubai-rest]`
It provides: a **real-estate wallet** (owner's properties, current prices, rental return, service charges); **off-plan project transparency** (completion %, actual project photos, escrow account number, dues payable); **lease management** via Ejari (register / renew / cancel); **rental dispute** filing; **valuation certificates**, **To Whom It May Concern** letters, **map issuance**; the **rental index** and **sale index**; directories of **brokers and their performance levels**, **offices/classifications**, **valuation companies**, **management companies**, **consultancies**, and **certified developers**; and **Noqodi** electronic payment. Available in Arabic + English, iOS + Android. `[SRC: dld dubai-rest]`
**DLD already runs its own AI assistant inside REST — "Malik," powered by OpenAI**, plus a voice agent. `[SRC: dld dubai-rest page]` → *Implication for our chatbot: do NOT imitate or claim to be Malik or an official DLD channel. We are the private-developer REST-literate assistant that guides to REST; the authoritative action stays in REST.*

PART 2 — THE FULL SERVICE CATALOG (verified from the DLD all-services page)
`[SRC: dld all-services?id=19503]` — grouped as DLD groups them. Each entry tagged **[C]=computable by us** or **[S]=sovereign / handoff**.
2.1 Real Estate Development Services
2.2 Real Estate Licensing Services
2.3 Real Estate Rental Services
2.4 Real Estate Transaction Services
2.5 Title Deed Data Services
2.6 Information / Inquiries (mostly [C] — this is our richest lane)
---
PART 3 — FEE & COST FORMULAS (the calculator engine spec)
All formulas below are what the chatbot computes. **Rates carry verify stamps because government fees change.**
3.1 DLD transfer / registration fee
3.2 Off-plan project registration (developer-side, context only)
3.3 Oqood initial-sale registration (off-plan)
3.4 Title-deed conversion at handover
3.5 Agent commission (secondary)
3.6 Ejari / tenancy
3.7 Golden Visa threshold (property route)
**Calculator rule:** every computed figure returns with its formula shown + a "rates last verified" date + a "confirm on DLD" pointer. Never present a fee as final/binding.
---
PART 4 — INDEXES (rental, sale, service charge)
- **Rental Index / Smart Rental Index** — DLD's basis for permissible rent and rent-increase caps (RERA rental increase calculator logic). The chatbot explains how an area/property maps to index rent and what increase %, if any, is allowed on renewal. Live values come from DLD; `// API` lookup stub in build. `[SRC: dld rental-index]`
- **Sale / Transaction Index** — historical + current transaction price levels by area/type; basis for "is this price in line with market." `[SRC: dld]`
- **Service Charge Index** — per-community annual service-charge rate (AED/sqft); the chatbot uses it to estimate holding cost. `[SRC: dld service-charge-index]`
**Discipline:** index *values* are live/moving data → `// API` or official-channel lookup, never hardcoded invented numbers. Index *methodology* (how to read it) is corpus knowledge and can be explained freely.
---
PART 5 — TRANSACTION LIFECYCLES (process knowledge the chatbot walks)
5.1 Off-plan purchase (developer → buyer)
5.2 Secondary / resale (owner → buyer)
5.3 Off-plan assignment (resale before completion)
5.4 Ejari (tenancy)
5.5 Gift / inheritance transfers
---
PART 6 — DOCUMENT REQUIREMENTS (per service — the pre-fill checklists)
**Oqood initial sale — individual:** signed SPA copy; valid UAE ID; valid passport (non-residents). **Minor:** guardian signs + guardian ID/passport. **Decree holder:** valid "To Whom It May Concern" from Federal Authority for Identity & Citizenship. `[SRC: dld initial-sale]`
**Oqood — company:** valid trade licence; UAE ID/passport of licence holder; POA if any; (LLC) legal-translated MOA + annexes (Arabic); shareholder certificate. `[SRC: dld initial-sale]`
**Corporate buyer/seller (2026):** **TRN** + proof of 9% corporate-tax compliance required before transfer initiates. `[SRC: 2026 corroborated] [VERIFY]`
**Secondary transfer:** signed Form F; NOC from developer; seller mortgage liability letter (if any); IDs/passports; Form A on file. `[SRC: form-F 2026]`
**Escrow reference (SPA Engine):** project escrow IBAN + RERA-approved trustee bank name (from the Approved Escrow Trustees directory). Funds go only here. `[SRC: dld certified-escrow-agents]`
---
PART 7 — VERIFICATION & DIRECTORY LOGIC (anti-fraud lane)
The chatbot can guide every REST verification and explain *what a clean result looks like*:
- **Broker/office:** licensed in the Licensed Brokers directory; valid **e-card**; valid **Trakheesi permit** on the specific ad. A broker not in the register, or an ad with no permit number, is a red flag. `[SRC: dld directories + form-A 2026]`
- **Developer:** in the Licensed Developers register.
- **Title deed:** authenticate via Verify Title Deed (guards against forged deeds).
- **Escrow trustee:** must be on the Approved Escrow Trustees list (Central-Bank-licensed, RERA-approved).
- **Valuation certificate:** verify via Taqyimee.
- **Payment safety rule (quote to buyers):** pay only to the named **Project Escrow Account** IBAN, verified through official channels — never to an individual or company operating account; refuse "off-book discount" payments. `[SRC: 2026 corroborated]`
---
PART 8 — THE SOVEREIGN BOUNDARY (hard rules the chatbot never crosses)
The chatbot **must not** claim to, or appear to:
- Register a project / sale / Ejari, submit Oqood, issue a title deed, or file with DLD directly.
- Sign anything via UAE PASS on a user's behalf, or generate a *legally valid* Form F outside REST.
- Move, hold, or receive money; process Noqodi payments.
- Issue any certificate of record (valuation, TWMC, rental certificate, deed).
- Impersonate Malik, DLD, RERA, or any official channel.
For each of these it instead: explains the service, runs the pre-flight checklist, **pre-fills the data package**, and **deep-links to the exact REST/MyDLD service** with the doc list ready. Framing: *"I've prepared everything — the final step happens on Dubai REST, where the law requires it."*
---
PART 9 — SOURCING & MAINTENANCE POLICY
- Structure/process/doc-lists = stable corpus knowledge (from DLD source), safe to state directly.
- Dirham fees + index values = **moving**; carry "last verified" dates; `[VERIFY]` before client-facing quotes; live values via `// API` or official lookup.
- Never invent a fee, IBAN, permit number, project number, or index value. Unknown → flag `[ — verify on DLD ]`, don't fabricate.
- Re-verify Part 3 fees and Part 4 indexes before any pitch; DLD updates the services site frequently (page footers showed May–June 2026 updates).
- All directory/verification results are *pointers to* the official register, not our assertions of licensure.

PART 10 — CHATBOT ANSWER CONTRACT (how every response is shaped)
1. **Answer from corpus** — grounded, sourced, with the formula or process shown.
2. **Compute if computable** — show the math + "rates last verified" date.
3. **Verify-guide if a lookup** — walk the official check; never assert licensure ourselves.
4. **Handoff if sovereign** — pre-fill + deep-link + doc checklist; state the legal reason.
5. **Never** fabricate figures or impersonate DLD. Uncertain → flag + point to DLD.
6. Bilingual EN/AR where possible (REST is bilingual); Arabic in proper Gulf/MSA register.
