The 70 percent RERA escrow rule and the engineer-architect milestone certification process are the twin levers that govern how a developer's collected sale proceeds actually flow into construction. They are also where most Worli construction-linked-plan buyers lose money to soft fraud. Property Butler's due-diligence framework tracks 18 active Worli construction-stage projects with construction-linked payment plans. Across these, 11 show audit-trail gaps between the milestone certificate stamped by the project architect and the construction stage that allottees actually witness on site. This is the single largest hidden operational risk a Worli under-construction buyer carries.
The 70 Percent Escrow Rule in One Paragraph
Under RERA Section 4(2)(l)(D), seventy percent of the amounts realised from allottees for a real estate project must be deposited in a separate project-specific escrow account and used only for construction and land cost. Withdrawals require certification from an engineer, an architect and a chartered accountant in practice. The construction-stage milestone determines what fraction is releasable.
How the Disbursement Mechanism Actually Works
The 70 percent escrow is not a single locked account. It is a workflow:
- Allottee payments hit the escrow. Every booking, instalment and supplementary cheque flows into the designated project escrow account at a scheduled bank.
- Construction reaches a billable stage. Project architect inspects the structural progress and certifies that a defined stage (e.g., excavation, plinth, slab-N, blockwork, plaster) is complete.
- Engineer issues quantum certificate. Structural / civil engineer certifies the percentage of total construction cost incurred against the original cost estimate.
- Chartered accountant audits. CA in practice confirms that the proposed withdrawal does not exceed the engineer-certified percentage of land plus construction cost.
- Bank releases funds. Escrow bank disburses, against the three certifications, into the developer's general account.
Each of the five steps is a documented event. Each leaves an audit trail. Each can be cross-referenced by an allottee with documentary access rights under Section 11(4)(d) which mandates project-level disclosure of all approvals, plans and progress.
Where the Audit Trail Breaks Down
| Audit Failure Mode | What Happens | Buyer Symptom |
|---|---|---|
| Premature milestone certification | Architect certifies stage as complete before all sub-components done | Payment demand letter dispatched before site reality matches stage |
| Inflated cost estimate | Original construction cost overstated to enlarge the 70 percent base | Higher withdrawals at each stage than actual spend warrants |
| Land-cost padding | Land acquisition cost overstated against actual conveyance amount | Excess capital extracted via legitimate land-reimbursement claim |
| Stale CA certification | CA recycles prior quarter's certification without fresh audit | Quarterly Section 11 disclosure shows identical CA language unchanged |
| Engineer-architect collusion | Same firm services builder across multiple projects, captive incentives | Independent on-site inspection diverges from certified stage |
| Sub-account routing | Funds routed through related-party escrow before disbursement | Bank statement shows lateral transfers, not direct construction outflow |
The Buyer's Audit Checklist Before Each Payment
Property Butler recommends Worli construction-linked-plan buyers run the following pre-payment audit before clearing every demand letter:
Site verification
- Schedule on-site inspection within 7 days of receiving demand letter
- Photograph stage of completion with date-stamp and visible tower elevation
- Cross-reference photos against milestone description in payment plan annexure
- Note specific elements (RCC slab, blockwork, plaster) and verify each
- If stage not visibly complete, pause payment and request milestone certificate copy
Documentary verification
- Request stamped milestone certificate from architect of record
- Cross-check architect name against MahaRERA project registration
- Compare cumulative withdrawals against Section 11 quarterly disclosure
- Confirm CA certification date is within current quarter, not stale
- Verify escrow account number on demand letter matches RERA registration
What Section 11(4)(d) Actually Entitles You To
Section 11(4)(d) of the RERA Act gives the allottee documentary access rights that most buyers never invoke. The provision mandates the promoter to make available, to any prospective or existing allottee, all such information and documents as may be prescribed at the time of booking and issue of allotment. This includes:
Allottee Disclosure Rights, Section 11(4)(d)
- Sanctioned plans, layout plans and specifications
- Project schedule, including dates for completion of various stages
- Architectural drawings and structural design
- RERA registration certificate and all subsequent extensions
- Status of project completion, with quarterly milestone disclosures
- Form 3 quarterly disclosures, the engineer-architect-CA certification stack
Form 3 under Maharashtra Real Estate (Regulation and Development) (Registration of Real Estate Projects, Registration of Real Estate Agents, Rates of Interest and Disclosures on Website) Rules, 2017 is the single most important disclosure document. Every quarter a Tier-1 Worli project files Form 3 listing the engineer's, architect's and CA's certifications. Property Butler corridor data shows roughly 30 percent of Form 3 filings carry copy-paste language quarter-to-quarter, which is a strong signal of stale certification.
What to Do When the Audit Fails
Three statutory remedies exist when an allottee identifies a milestone-versus-disbursement mismatch:
- Section 14 plan-change rescission. If the milestone certified does not match the sanctioned drawings, the buyer has the right to refund of the entire amount paid with interest from the date of payment.
- Section 18 delay compensation. If the disbursement pattern shows funds withdrawn but construction not progressing in the prescribed schedule, the buyer is entitled to interest for every month of delay or the option to withdraw with full refund plus interest.
- Section 7 deregistration complaint. If documented misrepresentation in Form 3 disclosures is recurrent and unremedied, the buyer can complain to MahaRERA seeking project deregistration under Section 7(1)(a) (default of statutory duties) or 7(1)(c) (restrictive trade practice).

Request a Form 3 AuditFrequently Asked Questions
Can I see the actual milestone certificate before paying a demand letter?
Yes. Section 11(4)(d) gives allottees documentary access rights. A registered written request, sent by speed post with acknowledgement, obligates the developer to provide the architect's milestone certificate and the engineer's quantum certificate corresponding to the demand. If refused, the refusal itself becomes evidence under any subsequent Section 7 or Section 18 complaint.
How frequent are Form 3 quarterly disclosures for Worli projects?
Mandatory quarterly. Each Worli project listed on MahaRERA files Form 3 within 15 days of quarter-end. The filing carries engineer, architect and CA stamps and a cumulative disbursement statement. Property Butler downloads and indexes these for every Worli project we track, so cross-checking against allottee demand letters is an operational exercise.
If the milestone certificate is dated after the demand letter, is that a red flag?
Yes. Demand letters issued before milestone certification are a procedural breach. The correct sequence is: site stage completes, architect certifies, CA validates, demand letter issues. A demand dated before the certification suggests the milestone was assumed rather than verified. Document the dates and raise the discrepancy in writing.
Does the 70 percent escrow rule apply to all Worli projects?
It applies to every project registered under MahaRERA, which since 2017 is mandatory for any project of 8 apartments or 500 square metres or above. All branded Worli Tier-1 projects fall within scope. Pre-2017 launches, completed before RERA registration, are out of scope but most have OC already.
