Since 16 February 2026, a partner change filed from Mumbai has landed with one of two registrars, and your registered office district alone decides which. Offices in Mumbai City and Mumbai Suburban districts file with ROC Mumbai-I. Offices everywhere else in the region, Thane and Panvel included, file with ROC Mumbai-II at Navi Mumbai. The LLP side of the split runs on MCA notification S.O. 4849(E), and most guides written earlier still describe a single ROC. Address a filing on that assumption and Form 4 sits in the wrong queue while its 30 day window quietly closes. Here is how a partner addition actually works for an LLP in this city, what ₹3,999 buys, and where every deadline sits.
What falls due when your LLP admits a new partner?
Three moves happen in order. First, the incoming partner consents and the existing partners approve the admission under the terms of the current agreement. Second, a supplementary deed amends the LLP agreement to record the new capital contribution and profit share. Third, two filings reach the registrar through MCA V3: Form 4 reporting the change in partners and Form 3 carrying the amended agreement. Each form runs on its own 30 day clock, and the clocks start on different dates.
| Filing | Window | What a miss costs |
|---|---|---|
| Form 4, notice of the new partner | 30 days from the date of admission | Additional fees that climb in slabs with the delay |
| Form 3, the amended agreement | 30 days from the supplementary deed | Slab fees plus a public record still showing the old deed |
| DIN for an incoming designated partner | Needed before Form 4 can go in | No fee by itself, but the 30 day clock keeps running |
| DIR-3 KYC for the new designated partner | Every year after DIN allotment | DIN deactivation until the KYC is made good |
Which registrar receives your Form 4?
The test takes ten seconds. Greater Mumbai, the area the BMC administers, is exactly the two districts of Mumbai City and Mumbai Suburban. A registered office inside those limits answers to ROC Mumbai-I. An office anywhere else answers to ROC Mumbai-II at Navi Mumbai, whose charge covers eight districts: Aurangabad, now Chhatrapati Sambhajinagar, Dhule, Jalgaon, Nandurbar, Nashik, Palghar, Raigad and Thane.
So a restaurant brand with its LLP registered in Bandra West files with the first office, while a logistics partnership registered in Bhiwandi files with the second. Where the partners themselves live never matters. Jurisdiction follows the registered office, and every form travels through the portal in any case, so neither office asks anyone to appear.
What does a late or thin filing actually cost?
Start with the figure older articles still quote. The uncapped additional fee of ₹100 a day on the LLP annual forms was replaced from 1 April 2022 by multiplier slabs of the normal filing fee. Event forms such as Form 4 and Form 3 likewise attract additional fees that climb with each band of delay. The meter is gentler than the old one, but it only ever runs against you.
The larger cost rarely shows up as a fee. A partner who signed a deed that never reached the register is invisible to banks, landlords, franchise counterparties and investors. Diligence teams pull master data before they read agreements, and when the record disagrees with the deed set, the transaction waits until the record is fixed.
Two Maharashtra layers add real money if ignored. The supplementary deed is chargeable under the Maharashtra Stamp Act, 1958, and the duty turns on the instrument and the value involved, so we compute the exact figure before execution and pay it electronically through GRAS. Separately, every LLP partner in the state carries a personal PTEC, a flat ₹2,500 a year enrolled on mahagst.gov.in, and incoming partners miss it constantly because national checklists never mention it.
Which Mumbai LLPs feel the pain first?
Partner additions cluster around a few recurring situations, and this city produces all of them in volume:
- Restaurant and retail brands. A Bandra West brand owner typically admits an operations lead or a family investor as partner just before signing the next outlet lease, and franchise counterparties now ask for the Form 4 receipt before they countersign.
- Technology founders. A Powai SaaS founder converting a senior engineer into a profit sharing partner files the same two forms, usually under time pressure from an investor closing date.
- Professional practices. Design studios and consultancies around Lower Parel admit associates to partnership at financial year end, which stacks both 30 day windows against audit season.
- Family trading houses. Kalbadevi textile firms admitting the next generation often discover the agreement on record has not matched reality for years.
How we run the filing for you
The engagement runs online from start to finish, and most additions close within two weeks. The sequence looks like this:
- Scoping call. We confirm the registered office district, which fixes your registrar, and settle whether the entrant joins as a partner or a designated partner.
- KYC and DIN. We collect the incoming partner's PAN, Aadhaar, address proof and photograph, then file the DIN application wherever the role needs one, because the 30 day clock will not wait for it.
- Supplementary deed. We draft the amendment recording contribution and profit share, compute the Maharashtra stamp duty, and arrange the electronic payment through GRAS before anyone signs.
- Form 4 on MCA V3. Filed with the consent attached, inside 30 days of the admission date.
- Form 3 with the amended agreement. Filed once the stamped deed is executed, on its own separate clock.
- Closure. We verify the updated master data, hand over every filed form and challan, and flag the new partner's personal PTEC enrolment.
What do we need from you?
From the incoming partner:
- PAN, Aadhaar and a recent address proof
- a photograph, plus a mobile number and email that receive OTPs
- the agreed contribution amount and profit share
From the LLP:
- the current agreement with every earlier supplementary deed
- the DSC of the designated partner who signs the filings
- the LLPIN and certificate of incorporation
No step needs anyone at a counter, and nothing is couriered. If you would rather plan it across a table, our office at Haware Fantasia Business Park in Vashi is open for exactly that, though your registrar is fixed by your registered office district, never by where we sit.
Why LegalX India in Mumbai?
Because the local layer is where additions go wrong. National filing portals treat Form 4 as a generic upload: stamp duty gets guessed, the wrong registrar gets addressed, and nobody mentions the incoming partner's PTEC. Our CA and CS team files with both Mumbai registrars every week and prices the work flat at ₹3,999 in professional fees. More than 15,000 businesses have used LegalX India. Our Google rating stands at 4.8 across over 2,500 reviews. Send us your current agreement and we will call back within 30 minutes with a document list and a filing calendar for both 30 day windows.
