The most expensive habit among Mumbai LLPs is treating a signed supplementary deed as the finish line. Partners agree on a new profit split, the deed is printed and signed over chai, and the papers settle into a cupboard in the back office. Nobody stamps the document. Nobody files Form 3. Months later a lender or a large customer asks for the agreement on record, and the registrar's copy still shows ratios that stopped being true last year.
The fix is sequence, not heroics. Draft the supplementary agreement, pay Maharashtra stamp duty before anyone signs, collect the signatures, then file Form 3 on MCA V3 within 30 days of the change. LegalX India runs that sequence for ₹1,499 and usually closes it in 7 to 10 days.
What has to reach the registrar, and by when?
Form 3 carries every amendment of the agreement to the registrar and falls due within 30 days of the change taking effect. Where a partner joins or exits, Form 4 rides along under the same clock. Here is the schedule as we apply it for Mumbai clients.
| Change in the deed | Filing | Deadline |
|---|---|---|
| Profit sharing or capital terms revised | Form 3 | 30 days from the change |
| Partner admitted or retiring | Form 3 with Form 4 | 30 days from the event |
| Business activities widened or narrowed | Form 3 | 30 days from the change |
| Name or registered office clause redrawn | Form 3 plus the separate address or name filings | 30 days from the change |
Two things about the clock deserve respect. It starts on the effective date written into the deed, not on the day you get around to filing, and it does not pause for stamping or signature delays. Build the paperwork backwards from day 30.
Both filings happen online on MCA V3. Nobody stands in a queue anywhere in the city, and the only physical step in the whole engagement is signing the stamped deed.
Mumbai-I or Mumbai-II: which registrar reads your Form 3?
Since 16 February 2026 the region has had two registrars, created for LLPs by notification S.O. 4849(E) with a parallel order for companies. The test is the district of the registered office. Mumbai City and Mumbai Suburban, the two districts that form the BMC area, belong to ROC Mumbai-I. The other eight districts, Thane, Palghar, Raigad, Nashik, Dhule, Jalgaon, Nandurbar and Chhatrapati Sambhajinagar, belong to ROC Mumbai-II at Navi Mumbai. The split did not change your LLPIN or your portal login; it changed which office examines what you file.
In practice, a Powai or Ghatkopar LLP files with Mumbai-I, while a Bhiwandi, Thane or Panvel LLP files with Mumbai-II. Older guides still describe a single ROC for the city, and a Form 3 prepared on that assumption addresses the wrong office. One more wrinkle: when the amendment itself shifts your registered office across the district line, Mulund to Thane for example, the registrar you answer to changes with it.
What does an unfiled amendment actually cost?
MCA V3 adds fees over the normal filing fee once the 30 day window lapses, and the meter runs until the day you file. The fee framework itself changed on 1 April 2022. The old uncapped ₹100 a day charge on the annual Forms 8 and 11 gave way to multiplier slabs then, and blogs still quoting flat daily penalties for LLP forms are reading from an old script.
The additional fee is rarely the real damage. An unfiled amendment means the public record contradicts your working reality. A partner who retired months ago still shows on it. A capital infusion everyone remembers has no filed basis. In a dispute, the partner relying on the unfiled deed argues uphill. And when a logistics client audits its Bhiwandi vendor before renewing a contract, the audit reads the filed agreement, not the one in the cupboard. Banks read filed records just as literally, and a working capital renewal can stall for weeks over a profit sharing clause that no longer matches the partners' income tax filings.
Which Mumbai LLPs does this bite hardest?
Four patterns repeat in our Mumbai files.
- Warehousing and logistics operators around Bhiwandi. Fleet partners rotate, capital arrives ahead of every new godown, and each change belongs in the deed before the next client audit reads it.
- Family textile businesses in Kalbadevi that converted the old partnership into an LLP and are now writing the next generation into the profit split.
- Service firms in Powai or Andheri East whose original deed lists activities they outgrew two pivots ago.
- LLPs moving the registered office across the district line, from Mulund to Thane say, without noticing that the registrar changes along with the address.
If you recognise your LLP in any of these, the cheapest day to file was the day of the change. The second cheapest is today.
How does LegalX India run the filing for you?
The engagement follows five fixed stages, and you can see where your file sits at any point.
- Scope the change. A company secretary hears what is changing, confirms which forms your situation triggers, and checks which side of the registrar split your district falls on.
- Draft the deed. We write the supplementary agreement so it reads consistently with the original, clause by clause.
- Stamp it. Stamp duty in Maharashtra depends on the instrument and value; we compute the exact figure before execution and have the duty, set by the Maharashtra Stamp Act, 1958, paid before anyone signs.
- Collect signatures. Every partner signs the stamped deed, and the designated partners keep their DSCs ready for the filing.
- File and track. Form 3, with Form 4 where partners change, goes onto MCA V3, and we chase it until the acknowledgment lands in your inbox.
What will we need from you?
The list is short, and most clients assemble it within a day. Delays usually come from papers arriving piecemeal, so we share the checklist upfront.
- The existing LLP agreement, along with any earlier supplementary deeds
- Your LLPIN and the district of the registered office
- A plain note of what is changing and the date it takes effect
- The partners' consent or resolution approving the change
- Digital signatures of the designated partners
- For partner changes, the incoming partner's DIN and KYC papers
