Account Variants: Institutional and Custodial Accounts

Why this page is structured this way: an institutional account is defined less by who the client is than by who settles the trade. The page therefore starts with the clearing model — execution member, clearing member, custodian — because that single fact determines the UCC category, the order-tagging rules, the intraday cut-offs and the margin treatment. Client types, family mapping and the sole-proprietor case follow, because each is a variation on the same clearing skeleton.

TL;DR

• Institutional clients separate execution from clearing. The broker executes; a custodian acting as clearing member confirms the trade and takes on the settlement obligation. The link between the two is the custodial-participant code carried on the order.
• Unconfirmed means unsettled by the custodian and therefore the broker’s own obligation. NSE Clearing’s custodial-participant procedures set the intraday windows — CP-code modification to 16:15, custodian trade confirmation to 19:30 on T, and obligation-transfer-request submission to 20:00 on T with confirmation into the following morning (NSE Clearing, “Custodial Participant Deals” and the NCL Clearing FAQ) [industry practice — unverified] on current values, which move with each settlement calendar. The published-timings template is NCL/CMPT/50078.
• A generic institutional code allows allocation after execution. Orders may be executed under a single institutional code and allocated to the underlying CP codes afterwards, with the break-up uploaded against the contract-note reference the same working day.
• Custodial participants can settle T+0, with a dedicated family mechanism. Eligible since 31 July 2024 per NCL/CMPT/63165, with the Family Account CP code (name suffix FAMILYAC, placeholder PAN FAMIL999999Y) active from 10 February 2025 per NCL/CMPT/66135 — the mechanics are in the T+0 and T+1 settlement deep dive.
• Institutional client categories occupy a distinct band of the UCC table — 12 development financial institution, 23 foreign institutional investor, 31 to 34 provident, superannuation, gratuity and pension funds, 36 mutual fund fund-of-funds schemes, 37 NPS Trust, 38 global development network, 39 FCRA — per the NSE and BSE client-category tables.
• A sole proprietorship is registered as category 13 on the proprietor’s PAN, because the proprietorship has no separate PAN of its own.
• UPI-based secondary-market payment does not reach institutional accounts — it applies only to categories 01 and 03.
• The CP-code requirement was removed for NRI clients by SEBI/HO/MIRSD/MIRSD-PoD/P/CIR/2025/109 (29 July 2025, in force 1 September 2025); it remains the model for genuine custodian-cleared flow.

Conceptual overview

In the retail model the broker is both the execution member and the clearing member: it places the order, it carries the obligation, it collects the margin, it settles. In the institutional model those roles split. A mutual fund, an alternative investment fund, a portfolio manager’s client, an insurance company or a pension fund appoints a custodian — a bank or a specialised custodian registered under the SEBI (Custodian) Regulations — to hold its assets and to clear its trades. The client then distributes execution across several brokers, and each executed trade is tagged with the custodian’s CP code so that the obligation lands with the custodian rather than the executing broker.

Everything operationally distinctive about these accounts follows from that split. The broker does not call for margin from the client in the retail sense, because the custodian posts margin against the confirmed obligation. The broker’s risk is not market risk on the position but confirmation risk on the trade: if the custodian rejects or fails to confirm within the window, the obligation reverts to the executing member, who then has an unhedged position and a pay-in to fund. Institutional desks therefore reconcile confirmations continuously through the day rather than in an end-of-day batch.

The KYC picture is correspondingly thinner and sharper. The broker still registers a unique client code against the client’s PAN and still holds the client agreement set, the authorised-signatory list and the beneficial-ownership record appropriate to the entity’s constitution — a mutual-fund scheme is a trust, an AIF is usually a trust, an insurer is a company, a portfolio manager’s client may be an individual. What it does not do is build the depository relationship: the securities sit in the custodian’s demat arrangement, not in a demat account the broker’s DP opened.

The sole-proprietor case sits at the opposite end and is included here because it is the last remaining non-individual shape a retail broker meets. A proprietorship is not a person at all: it is an individual trading under a business name, so the PAN, the KYC and the liability are the proprietor’s, while the bank account and the trade name are the business’s.

1. Regulatory framework

• SEBI/HO/MIRSD/MIRSD-PoD/P/CIR/2025/90 — Master Circular for Stock Brokers (April 2025), consolidating broker obligations to 31 March 2025 including client registration, running-account settlement and margin obligations that apply differently to custodian-cleared clients.
• SEBI/HO/MIRSD/SECFATF/P/CIR/2023/169 (12 October 2023) — Master Circular on KYC norms; the non-individual annexure governs the constitution-specific document set for each institutional client type.
• SEBI/HO/MIRSD/SECFATF/P/CIR/2024/78 (June 2024) — AML/CFT Master Circular: customer due diligence and beneficial-owner identification, which for a fund means tracing to the sponsor, trustee, investment manager and controlling persons.
• SEBI/HO/MIRSD/MIRSD-PoD/P/CIR/2025/109 (29 July 2025, in force 1 September 2025) — operational efficiency in monitoring NRI position limits in exchange-traded derivatives; removes the CP-code requirement that had applied to NRI clients, leaving CP codes to genuine custodial flow. See NRI.
• NCL/CMPT/63165 (31 July 2024) — extends the T+0 rolling settlement cycle to custodial-participant transactions.
• NCL/CMPT/66135 (15 January 2025, effective 10 February 2025) — operational clarifications for T+0 custodial-participant transactions; activates the Family Account CP code with name suffix FAMILYAC and placeholder PAN and SEBI registration FAMIL999999Y, restricted to non-marginable CP codes, with trade confirmation at family-account level and obligations at individual CP level. Annexure 1 timings: regular market close 13:30, early-pay-in cut-off 13:45, custodian trade-confirmation cut-off 14:45, securities pay-in 15:30, funds pay-in 16:00.
• NCL/CMPT/50078 (22 October 2021) — the template for how obligation-transfer-request, CP-code modification and confirmation windows are published for a given session.
• SEBI (Portfolio Managers) Regulations 2020 — a portfolio manager must appoint an independent custodian except where it provides only advisory services, and cannot hold client securities in its own name; client-level accounts are maintained by the custodian.
• SEBI (Custodian) Regulations 1996, as amended by SEBI/LAD-NRO/GN/2026/308 (3 July 2026) — custodian fees move from annual to monthly, payable within 15 days after month-end, from 1 October 2026.
• NSE Clearing, “Custodial Participant Deals” and the NCL Clearing FAQ — CP-code allotment through the clearing front-end, the generic institutional code, obligation-transfer-request mechanics and the intraday cut-offs. Named public documents rather than numbered circulars.

2. The clearing model and the CP code

Step	Who acts	What happens	Timing reference
1. CP-code allotment	Clearing member or custodian	Applies through the clearing corporation’s front-end; the code is unique to the constituent and active from the next trading day	NSE Clearing, “Custodial Participant Deals”
2. Client-to-CP mapping at the broker	Broker	Maps the client’s UCC to the CP code in the order-management system so that orders carry it automatically	Broker configuration
3. Order entry	Broker	Order carries the CP code, or a generic institutional code where allocation will follow	Intraday
4. CP-code modification	Broker	Correcting or assigning the CP code on executed trades	Up to 16:15 [industry practice — unverified]
5. Allocation break-up	Broker	Uploads the break-up of obligations across institutional clients with the contract-note reference	Same working day
6. Custodian confirmation	Custodian	Confirms the trades; on confirmation the obligation is the custodian’s	Up to 19:30 on T [industry practice — unverified]
7. Obligation transfer request	Broker	Reallocates CP codes after trading hours where confirmation or allocation needs correction	Up to 20:00 on T, confirmed into T+1 morning [industry practice — unverified]
8. Rejection handling	Broker	Unconfirmed or rejected obligations revert to the executing member	Immediately on window expiry
9. Settlement	Custodian or broker	Confirmed obligations settle through the custodian; reverted obligations settle through the broker	Per settlement calendar

Confirmation risk is the whole risk

For a retail client the broker’s exposure is the client’s ability to pay. For an institutional client it is the custodian’s willingness to confirm. A trade executed against a limit the custodian’s own system does not recognise — a stale limit file, a mandate breach, a wrong CP code — will be rejected, and the obligation lands on the executing member after the market has closed and with no ability to square off until the next session. Reconcile confirmations at least hourly through the afternoon, alert on any unconfirmed institutional trade by 18:00, and treat the confirmation cut-off, not the market close, as the end of the trading day for these accounts.

Give-up and take-up

Give-up and take-up is the same idea expressed through membership rather than custody: the executing member “gives up” the trade and a different clearing member “takes it up” and carries the obligation. The exchange and clearing corporation define the file format and the confirmation window; the broker-side mechanics are summarised in the broker process narrative, and the order-management plumbing — trade-capture reports for off-book and give-up flows — is in OMS internals. From the client-facing side the only thing that changes is the mapping table: the client agreement must name the clearing member, and the broker must hold that member’s acceptance before the first trade.

3. Client types and how each is onboarded

Client type	Constitution	UCC category	Who signs	What the broker holds
Mutual fund scheme	Trust; the asset management company acts for it	36 for fund-of-funds schemes; other schemes registered per exchange guidance	Authorised officials of the AMC	Trust deed, SEBI registration, AMC authorisation, scheme PAN, custodian mapping
Alternative investment fund	Usually a trust; sometimes an LLP or company	Per constitution and exchange guidance [industry practice — unverified]	Trustee or investment manager under the fund documents	Trust deed, SEBI AIF registration, investment-management agreement, PAN, custodian mapping
Portfolio management client	The client is an individual or entity; the portfolio manager acts under a power of attorney	The client’s own category — 01, 03, 04 and so on	Client, with the portfolio manager operating under the PMS agreement and POA	PMS agreement, POA, client KYC per the client’s own constitution, custodian mapping
Insurance company	Company	04 or 07	Board-authorised officials	Certificate of incorporation, IRDAI registration, board resolution, PAN
Provident, superannuation, gratuity, pension fund	Trust	31, 32, 33, 34	Trustees	Trust deed, recognition or approval, trustee resolution, PAN
NPS Trust	Statutory trust	37	Authorised officials	Constitutive instrument, authorisation, PAN
Development financial institution	Statutory or corporate	12	Authorised officials	Constitutive statute or incorporation documents, authorisation, PAN
Foreign institutional investor / FPI	Per home jurisdiction	23	Investment manager or custodian under POA	Registration certificate, PAN, LEI, POA — see FPI and FVCI
FCRA entity	Trust, society or Section 8 company	39	Trustees or office bearers	FCRA registration, designated account details, constitutive documents — see Trust, society and AOP
Sole proprietorship	Not a separate person	13	The proprietor	Proprietor’s PAN and KYC, business registration proof, business bank account

The entity-level document sets are not repeated here: a fund that is a trust is onboarded using the trust document set in Trust, society and AOP, and an insurer using the company set in Company. What this page adds is the clearing layer that sits on top of whichever constitution applies.

Portfolio management clients are not institutional clients

This distinction causes more implementation confusion than any other on this page. In a PMS relationship the client is the account holder — an individual, an HUF, a company — and the portfolio manager operates under an agreement and a power of attorney. The UCC is registered in the client’s name and category, the client’s own KYC applies, and the custodian maintains client-level accounts because the portfolio manager may not hold client securities in its own name. The portfolio manager is an operator, not the client. A system that registers the portfolio manager as the client will produce wrong tax reporting, wrong contract notes and wrong position limits.

4. Sole proprietorship accounts

Aspect	Treatment
PAN	The proprietor’s individual PAN; a proprietorship has no PAN of its own
UCC category	13 Sole Proprietorship
Client name	The proprietor’s name, with the trade name recorded as the business name where the exchange record supports it
KYC	Individual KYC of the proprietor, plus business-existence proof
Business proof	GST registration, Shops and Establishments registration, Udyam registration, professional licence, or an income-tax return showing business income [industry practice]
Bank account	Current account in the business name, with the proprietor as the sole authorised signatory
Demat account	In the proprietor’s own name; the trade name cannot hold securities
Liability	Unlimited and personal to the proprietor
Nomination	Available, because the underlying holder is an individual
Third-party payment risk	The business current account is not a third-party account, because the proprietor and the business are the same person — but the name mismatch will trip naive penny-drop matching

The recurring implementation defect is treating category 13 as a non-individual path. It is an individual account with a business overlay: individual KYC, individual demat, individual nomination, business bank account and business proof.

5. Field deltas at each destination system

Field	Type	Length	Mandatory	Source system	Destination systems	Notes
Client category	N	2	Yes	Onboarding form	NSE UCC, BSE UCC	12, 13, 23, 31–34, 36–39 per client type
Client PAN	AN	10	Yes	Onboarding form	KRA, CKYC, UCC, back-office	Scheme PAN for a fund; proprietor PAN for category 13
CP code	AN	—	Yes for custodian-cleared	Clearing corporation	Order-management system, obligation allocation, back-office	Mapped to the UCC; wrong mapping causes rejection
Clearing member code	AN	—	Yes where give-up applies	Exchange membership records	OMS, clearing files	Names the member taking up the trade
Custodian name and identifier	AN	—	Yes	Client instruction	Client master, reconciliation	Drives the confirmation workflow
Family Account CP code	AN	—	Conditional	Clearing corporation	T+0 allocation	Name suffix FAMILYAC, PAN and SEBI registration FAMIL999999Y; only non-marginable CP codes may be linked
Institutional generic code	AN	—	Conditional	Exchange convention	Order entry	Used where allocation follows execution
Authorised-signatory block	AN	—	Yes	Constitutive documents	Instruction verification, CKYC related persons	Per the entity’s own constitution
Beneficial-owner block	—	—	Yes	Declaration	CKYC, AML screening, CDD file	Traced per the entity’s constitution type
SEBI registration number	AN	—	Yes for regulated entities	Registration certificate	Client master, risk categorisation	Mutual fund, AIF, portfolio manager, FPI
FATCA entity classification and GIIN	AN	—	Yes	Declarations	KRA, FATCA/CRS reporting	Funds and insurers classify as financial institutions
Margin source flag	AN	—	Yes	Configuration	Risk-management system	Distinguishes custodian-posted margin from client-collected margin
UPI eligibility	—	—	Not applicable	—	Payment rails	Categories 01 and 03 only
Business name	AN	—	Conditional	Business proof	UCC, back-office, contract notes	Category 13 only

Field provenance across destinations is in the field atlas; the exchange-registration block is at U — exchange registration.

6. Family and mapped accounts

Two unrelated things travel under the word “family” and they should not be conflated.

Mechanism	What it is	Where it operates	Constraint
Family Account CP code	A clearing-corporation construct for T+0 custodial settlement: a parent CP code with the FAMILYAC suffix and placeholder PAN FAMIL999999Y, to which participating CP codes are tagged; confirmation happens at family level, obligations remain at individual CP level, and the custodian settles to the end investor within the day	Clearing corporation and custodian, per NCL/CMPT/66135	Only non-marginable CP codes may be linked; custodian maintains the audit trail
Broker-level family mapping	A servicing convenience: linking a client’s accounts to those of declared family members for a consolidated view, a combined holdings statement, or to whitelist a family member’s bank account against third-party-payment controls	Broker’s own systems and, for consolidated demat viewing, depository investor-facing services	Does not permit pooling of funds, securities or margin across PANs [industry practice — unverified]

The line that must not be crossed is margin and ledger pooling. Each PAN is a separate client with a separate ledger, a separate margin obligation and a separate reporting trail; a family mapping that lets one PAN’s credit support another PAN’s position is an inter-client transfer, not a feature. Consolidated viewing is safe; consolidated obligation is not. The upstreaming and segregation machinery that makes this concrete is in client funds upstreaming.

7. Alternatives

Option	Who it suits	Trade-off
Broker as both execution and clearing member	Mid-size corporates and funds without a custodian mandate	Broker carries the full obligation and collects margin directly; simpler operationally, heavier on the broker’s capital
Custodian-cleared with CP code	Mutual funds, AIFs, insurers, pension funds, FPIs	Obligation moves to the custodian, but the broker lives inside the confirmation cut-offs and carries rejection risk
Give-up to a separate clearing member	Clients who execute with many brokers but clear with one member	Requires the clearing member’s standing acceptance; adds a second confirmation dependency
Direct corporate account without custodian	Corporate treasuries trading modest size — see Company	Full corporate CDD on the broker, direct margin and pay-in
PMS relationship	Individuals and entities delegating discretion	The client remains the client; the portfolio manager operates under POA with an independent custodian
Sole proprietorship account	Individual businesses	It is an individual account with business documents, not a non-individual account

Practical notes

• [gotcha] The CP-code-to-UCC mapping table is the single highest-consequence configuration object on an institutional desk. A stale entry produces a trade the custodian will not recognise, discovered after the confirmation window. Version-control it, review it on every client or custodian change, and reconcile it against the clearing corporation’s master weekly. [industry practice]
• [gotcha] Cut-off times published in settlement-calendar and session-timing circulars move — holiday sessions and Muhurat sessions have their own schedules, of which NCL/CMPT/50078 is the template. Read the timings from the applicable circular each session rather than hard-coding them.
• [risk trade-off] Allocating under a generic institutional code and breaking up afterwards improves execution quality but concentrates operational risk into the post-close window. Desks that execute large institutional blocks should staff the allocation and confirmation window as deliberately as they staff the open.
• [gotcha] The CP-code requirement was removed for NRI clients from 1 September 2025 by SEBI/HO/MIRSD/MIRSD-PoD/P/CIR/2025/109. Code paths that branch on “foreign or institutional” rather than on the actual clearing arrangement will either keep demanding a CP code from NRIs or drop it from genuine custodial clients.
• [industry practice] Institutional clients are the group for whom the broker’s obligations under running-account settlement and margin collection differ most from retail, because the custodian posts margin. Model the margin source as an explicit flag rather than inferring it from the client category. [industry practice — unverified]
• [gotcha] A PMS client’s contract notes, capital-gains statements and tax reporting must be in the client’s name, not the portfolio manager’s. Registering the portfolio manager as the client corrupts all three and is very expensive to unwind after a financial year has closed.
• [cost optimization] For sole proprietorships, reuse the individual onboarding flow end to end and add only two artefacts: business-existence proof and a business bank account with relaxed name matching. Building a separate non-individual path for category 13 duplicates work and produces the wrong demat treatment.
• [gotcha] Family mapping must never be implemented as shared margin or shared ledger across PANs. Consolidated viewing, consolidated statements and whitelisted family bank accounts are defensible; anything that lets one PAN’s balance meet another PAN’s obligation is an inter-client transfer.
• [industry practice — unverified] Custodians commonly publish their own daily limit files to executing brokers, and many rejections trace to the broker trading against a limit file it did not refresh. Automate the refresh and alert on staleness rather than relying on the desk to notice.
