Which Forum Hears Your Redevelopment Dispute — Co-operative Court, MahaRERA, High Court or Consumer Forum?

The right forum for a Mumbai redevelopment dispute depends on two simple questions: who you are in dispute with, and what the dispute is about. Internal society matters — elections, membership, or how a redevelopment resolution was passed — go to the Co-operative Court under Section 91 of the Maharashtra Co-operative Societies Act, 1960 (the "MCS Act"). Delay or unauthorised plan changes in a RERA-registered project go to MahaRERA under Section 31 of the Real Estate (Regulation and Development) Act, 2016 ("RERA"). Enforcing or ending the development agreement is usually an arbitration or civil-court matter, with the Bombay High Court supervising. A "deficiency of service" by the builder can go to a consumer forum under the Consumer Protection Act, 2019. And outright cheating or misuse of society money is a criminal matter for the police and a magistrate. This page is general legal information, not legal advice for your particular case, so always confirm your route with a lawyer before you file.

The decision table: your dispute, your forum, and what you actually file

Find your row. The last column is the document that has to leave your hands — not a description of it. Every provision below is a section of a statute you can look up and quote in your covering letter.

Why picking the right door matters so much

Each forum has its own powers, procedure and — crucially — its own time limits. File in the wrong place and your society can spend a year or more only to be told the forum has no jurisdiction to hear you. You then start again elsewhere, often with the limitation clock (the deadline for filing) now working against you, and sometimes with a defaulting developer using the delay to dig in. Choosing correctly at the very start protects your members' time, money and legal rights.

Think of it as five different doors. Behind each sits a different law, a different decision-maker, and a different kind of relief. The rest of this guide explains what each door handles, which provision fixes the boundary between them, what document opens it, and what your managing committee has to record in the minute book on the way.

The five forums — and what each one decides

1. Co-operative Court and the Registrar — society governance

Set up under the MCS Act, these bodies deal with the internal life of the society: the managing committee and elections, membership and transfer disputes, alleged irregularities in a Special General Body Meeting (SGBM), and whether a redevelopment resolution or the members' consent was obtained correctly. Section 91(1) of the MCS Act is wider than most committees assume. It covers a dispute touching the constitution, the elections of the committee or its officers, the conduct of general meetings, and the management or business of a society. A badly convened SGBM is therefore squarely within it — you do not have to stretch the words "business of the society" to get there.

Section 91(1) then applies a second, harder test: both sides must fall within the list of parties it sets out — the society, its committee or any past committee, any past or present officer, agent or servant; a member, past member or a person claiming through one; a surety; or another society. If your opponent is not on that list, the Co-operative Court cannot hear you however strong your case is. Once a dispute is within Section 91, Section 163 bars the civil court from touching it, so filing a civil suit instead simply loses you the time.

What you file: a dispute application under Section 91, with court fee, accompanied by a certified true copy of the resolution authorising the filing, the minutes of the meeting complained of, and an extract of the I-Register. Before you file: if you are suing the society or an office-bearer in a civil court over an act touching its business, Section 164 requires two months' written notice delivered to the Registrar first — the suit is not maintainable until that period expires. Your deadline: Section 92 fixes the limitation and it varies with the kind of dispute, so fix the date against that section on the day the grievance arises.

The Registrar (and the Deputy or District Deputy Registrar) also plays a hands-on role in redevelopment itself. Under the Section 79A State directive dated 4 July 2019, the Registrar appoints an authorised officer to attend and video-record the developer-selection SGBM, where a 2/3rd quorum must be present and the developer must be approved by not less than 51% of the society's total membership. Complaints that this process was rigged or short-circuited are raised on this governance track. To understand the ground rules the committee must follow, read your society bye-laws and the 51% consent rule.

2. MahaRERA — registered projects, delay and plan changes

The Maharashtra Real Estate Regulatory Authority regulates registered real estate projects under RERA. Where the redevelopment project is registered and existing members are allotted new flats, they are generally treated as "allottees" and can file a complaint under Section 31 of RERA. MahaRERA is the natural forum for three things: delay in handing over possession (Section 18 lets an allottee claim a refund with interest, or interest for the period of delay, if the promoter fails to deliver on time); changes to the sanctioned plans or carpet area made without the previous consent of at least two-thirds of the allottees (Section 14(2)); and defects in structure, workmanship, quality or services, which must be reported to the promoter within five years of handover and rectified free of charge within 30 days, under Section 14(3).

Check the gate before you draft anything. MahaRERA's jurisdiction depends on the project being registrable. Under Section 3(2)(a) of RERA, registration is not required where the land proposed to be developed does not exceed 500 sq m or the number of apartments does not exceed eight, inclusive of all phases. A small society redevelopment can fall outside RERA altogether — in which case MahaRERA is not your forum and the contract and consumer routes are. Search the project on the MahaRERA portal and note the registration number and the promoter's declared completion date; those two entries are the backbone of a delay complaint. Your standing comes from Section 2(d), which defines an allottee as the person to whom an apartment has been allotted, sold or otherwise transferred by the promoter — a member allotted a new flat under a registered agreement answers that description on the words of the section.

Two different officers, two different applications. The Authority decides a Section 31 complaint and can direct completion, refund and interest. A claim for compensation under Sections 12, 14, 18 and 19 goes instead to the Adjudicating Officer under Section 71, on a separate application quantifying your loss head by head. Societies routinely lose their compensation claim by never making that second application. An order for interest, penalty or compensation is recoverable as an arrear of land revenue under Section 40. And if the promoter appeals, Section 43(5) stops the Tribunal from even entertaining the appeal until the promoter deposits at least 30% of the penalty, or the whole amount payable to the allottee including interest and compensation, whichever is higher — a fact worth putting in writing to a builder threatening to "appeal all the way".

MahaRERA can direct the developer to complete the work, pay interest for delay, or pay compensation, and its orders are enforceable as a decree. If your builder has stalled, read builder delay: what your society can do before you file, and check the promoter's duties in our note on MahaRERA promoter obligations. A MahaRERA order is appealed to the Maharashtra Real Estate Appellate Tribunal within 60 days of receiving a copy of the order (Section 44(2)), and from the Tribunal to the Bombay High Court within 60 days of the decision being communicated (Section 58).

3. Bombay High Court, arbitration and the civil courts — the agreement and public authorities

Disputes about the development agreement itself — enforcing it, terminating a non-performing developer, or claiming damages — are contract disputes. Most modern redevelopment agreements contain an arbitration clause, in which case the fight goes to a private arbitrator; the Bombay High Court appoints the arbitrator where the parties cannot agree and later hears any challenge to the award. (Remember that the development agreement and the Permanent Alternate Accommodation Agreement must be registered under Section 17 of the Registration Act, 1908 — an unregistered agreement weakens your hand in any of these forums.) Where there is no arbitration clause, the society files a civil suit in the City Civil Court or the High Court, depending on the value, seeking reliefs such as specific performance or an injunction. For the mechanics of ending a defaulting builder's contract, see terminating a non-performing developer.

The exact steps on the arbitration track. Arbitration does not start when you write a letter of complaint. Under Section 21 of the Arbitration and Conciliation Act 1996, the arbitration commences on the date the request to refer the dispute is received by the other side — so send the notice invoking arbitration by a mode that proves delivery, and keep that proof, because it fixes your commencement date. If the developer will not agree on an arbitrator, apply to the Bombay High Court under Section 11. If the site needs protecting in the meantime — materials being removed, third-party rights being created — apply for interim measures under Section 9. Once an award is made, a challenge under Section 34 must be filed within three months of receiving it, extendable by 30 days only and only on sufficient cause. That is the shortest clock on this page.

An arbitration clause binds only the parties to that agreement. The society signs the development agreement; individual members usually do not. A member's own claim against the promoter therefore does not automatically go to arbitration merely because the society's agreement says so. Check whose name is on the document before assuming the route.

Registration is not a formality. Under Section 23 of the Registration Act, a document must be presented for registration within four months of execution; beyond that, registration is possible only under Section 25, within a further four months, on payment of a fine. Under Section 49, an unregistered document that ought to have been registered cannot be received as evidence of the transaction. Separately, Section 13(1) of RERA bars a promoter from taking more than 10% of the cost of an apartment before a written agreement for sale is executed and registered — a useful line to quote when a builder asks for money against an unregistered "letter of intent".

The High Court also has a separate writ jurisdiction (under Article 226 of the Constitution). This is used to challenge decisions of public authorities — an order of the Registrar, a municipal or planning permission under DCPR 2034, or a final order of the RERA Appellate Tribunal. Writ is about the legality of a government decision, not a private contract quarrel.

4. Consumer forums — deficiency of service

Flat purchasers are "consumers", and where there is a deficiency in service — serious construction defects, broken promises about amenities, or a failure to deliver what was paid for — a complaint can be filed before the District, State or National Consumer Disputes Redressal Commission under the Consumer Protection Act, 2019. Consumer forums can order the builder to complete the work, refund money, or pay compensation. A co-operative society can complain in its own name: "person" under Section 2(31) includes a co-operative society. Watch the exclusion in Section 2(7) — services availed for a commercial purpose are outside the Act.

The tier is fixed by value, and the value is what was paid as consideration — not what you are claiming as damages.

Where you can file is set by Section 34(2): where the opposite party resides or carries on business, where the cause of action arose wholly or in part, or — a change the 2019 Act introduced — where the complainant resides or personally works for gain. By when: two years from the date the cause of action arose, under Section 69(1); a delayed complaint can be admitted only if the Commission records its reasons for condoning the delay, so plead the delay expressly rather than hoping it is overlooked.

5. Police and criminal courts — cheating and breach of trust

The forums above deliver money, possession or an order. They do not punish. Where a developer or an office-bearer acts dishonestly, a criminal complaint is a separate track. Under the Bharatiya Nyaya Sanhita, 2023 (which replaced the old Indian Penal Code), Section 318 (cheating) applies where there was dishonest intent from the very start — for example, a builder who never intended to perform. Section 316 (criminal breach of trust) applies where money or property was received lawfully and then misused — for example, corpus or rent funds diverted for other purposes. The two cannot be alleged on the same set of facts. A criminal complaint goes to the police and then a magistrate, and can run alongside a civil or MahaRERA claim.

The two steps, in order. First, a written complaint at the police station with territorial jurisdiction, registered as an FIR under Section 173 of the Bharatiya Nagarik Suraksha Sanhita, 2023. Ask for the FIR number and a free copy — you are entitled to one. If the police will not register it, the second step is an application to the Magistrate under Section 175(3) of the BNSS for a direction to investigate. Attach the same complaint and the proof that you sent it to the police. Offences of this gravity are not time-barred, but bank records, site records and witnesses decay quickly, so the practical deadline is set by your evidence, not by a statute. Our guide on filing an FIR against a builder explains when this route makes sense — and when it does not.

Where the statute itself draws the line — three tests you can apply yourself

You do not need a judgment to work out most of this. Three provisions decide the boundaries, and you can read each of them in a minute.

Test 1 — Is your opponent on the Section 91 list?

The single most expensive mistake committees make is assuming that because the society is a co-operative, every redevelopment fight belongs in the Co-operative Court. Section 91(1) itself answers this. It requires both parties to the dispute to fall within its stated categories: the society, its committee or a past committee; a past or present officer, agent or servant; a member, past member or a person claiming through one; a surety; or another society. A developer appointed under a development agreement is a contracting third party and is not on that list. So a society-versus-developer contract dispute does not fit Section 91 on the words of the section, and belongs instead to arbitration, the civil court, MahaRERA or a consumer commission depending on the relief you want. Conversely, once a dispute is within Section 91, Section 163 shuts the civil court out of it, so the mistake runs both ways.

Test 2 — Is the project registered, and are you an "allottee"?

MahaRERA is a creature of registration. Section 3 requires registration of the project, subject to the exemption in Section 3(2)(a) for land not exceeding 500 sq m or a project of not more than eight apartments. Section 2(d) defines an allottee as the person to whom an apartment has been allotted, sold or otherwise transferred by the promoter, and expressly excludes a person to whom an apartment is merely given on rent. An existing member who is allotted a new flat under a registered agreement in a registered project answers that definition on its own terms. Section 14(2) then locks the plans: no alteration to the sanctioned plans without the previous consent of at least two-thirds of the allottees. That is the provision behind our companion note on why changing sanctioned plans needs consent.

Test 3 — Which statute has the overriding clause, and which is only additional?

The overlap between MahaRERA and the consumer commission is not a grey area invented by lawyers; it is written into both Acts. Section 88 of RERA says the Act is in addition to, and not in derogation of, other laws. Section 100 of the Consumer Protection Act 2019 says the same of that Act. So neither remedy is abolished by the other. But Section 89 of RERA gives RERA overriding effect where another law is inconsistent with it, and Section 79 bars a civil court from entertaining any matter that the Authority, the Adjudicating Officer or the Appellate Tribunal is empowered to determine. The practical reading for a committee: the consumer route survives, the civil suit for a RERA-determinable matter generally does not, and running two forums for the same relief gives the developer an easy preliminary objection. Pick one route per grievance and say so in your minutes.

Where the fight is instead about the legality of a government decision — a planning permission, an order of the Registrar, or an order of the Appellate Tribunal — the remedy is the High Court's writ jurisdiction under Article 226, because that jurisdiction is directed at public authorities and not at a private contract quarrel. Where a planning authority has refused development permission or imposed conditions, note also the statutory appeal under Section 47 of the Maharashtra Regional and Town Planning Act, 1966; read that section for the period, because it is short. The through-line: the forum follows the nature of the relationship and the relief, not merely the fact that a co-operative society is involved.

The document pack — get these before you draft anything

Cases are lost on missing paper far more often than on bad law. Each row below is a document, the forum that will demand it, and the office it comes from.

What the committee must minute, and when

• Before filing anything: a resolution authorising a named office-bearer to institute proceedings, stating the forum, the opponent and the relief sought. A certified true copy is annexed to the filing. A resolution that says only "to take legal action" is routinely challenged as insufficient authority.
• On the day any order is received: minute the date of receipt and initial the envelope. RERA s. 44(2) runs 60 days from receipt of a copy of the order; Consumer Protection Act s. 41 runs 45 days. Limitation arguments are won and lost on this one entry.
• When you choose a forum: minute the choice with reasons, and record that the society will not pursue the same relief elsewhere. This is your answer to the developer's inevitable objection that you are running parallel proceedings.
• At the developer-selection SGBM: minute the name and designation of the Registrar's authorised officer, the fact and custody of the video recording, and the vote count against the 51% of total membership required by the 79A directive of 4 July 2019. Then resolve to preserve the recording.
• When a defect appears after possession: minute the date it was noticed and the date written notice went to the promoter. RERA s. 14(3) gives you five years from handover to raise it, and gives the promoter 30 days to rectify free of charge.
• When appointing an advocate: minute the appointment, the scope and the fee sanction. An unsanctioned fee becomes an audit objection and, occasionally, a s. 88 proceeding against the office-bearer who paid it.

What this means for your society — a practical checklist

• Apply the Section 91(1) party test first. Write down who you are actually fighting. If that person is not the society, its committee, a past or present officer, agent or servant, a member or past member, a surety or another society, the Co-operative Court cannot hear you — and a developer is none of those.
• Check the RERA gate, not just the RERA website. Registration is not required where the land does not exceed 500 sq m or the apartments do not exceed eight, under Section 3(2)(a). Confirm which side of that line your project falls on, then print the registration page with the promoter's declared completion date and keep the printout dated.
• Read your development agreement first. An arbitration clause decides how contract disputes are resolved and can override your instinct to rush to court. Our red flags in a development agreement guide shows what to look for, and a free tender and agreement review can catch these problems before they become disputes.
• Do not run two forums for the same relief. There is real overlap between MahaRERA and the consumer forum on delay and defects. Pick the single strongest route for your facts and evidence rather than filing everywhere.
• Diarise three dates the moment a dispute starts. The date the cause of action arose (two years for a consumer complaint, s. 69). The date any order is received (60 days to the RERA Tribunal, s. 44(2); 45 days to the State Commission, s. 41). And the date an arbitral award reaches you (three months to challenge under s. 34(3), extendable by 30 days only).
• Serve the Section 164 notice before you draft the plaint. If the society or an office-bearer is to be sued in a civil court over an act touching the society's business, two months' written notice must be delivered to the Registrar first, and the two months must actually expire.
• Keep your paperwork forum-ready. Registered agreements, meeting minutes, the video record of the selection meeting, and consent letters are your evidence in any forum. An unregistered agreement is the worst gap of all — Section 49 of the Registration Act keeps it out of evidence altogether.
