FINRA Rule 11550

Paragraph (a), General Requirements, establishes that any registered security to be good delivery must be accompanied by an assignment and, when required under paragraph (g), a power of substitution conforming to the requirements of FINRA Rules 11550 through 11574, with any expense from a seller's failure to meet these requirements borne by the seller. 

Paragraph (b), Assignment, governs whether an assignment is executed on the certificate itself or on a separate paper. 

Paragraph (c), Signature Requirements, establishes the technically correct signature standard. 

Paragraph (d), Detached Assignment Requirements, specifies the content a separate assignment must contain. 

Paragraph (e), Two or More Names, requires all registered owners' signatures for jointly registered certificates. 

Paragraph (f), Alteration or Correction, requires an explanation accompanying any alteration. 

Paragraph (g), Power of Substitution, governs the blank-execution chain when attorneys and substitute attorneys are named. 

Paragraph (h), Guarantee, requires a guarantee acceptable to the transfer agent or registrar, without mandating any specific guarantor. 

Paragraph (i), Foreign Internal Securities, exempts most foreign internal registered securities from paragraphs (b) through (g) and FINRA Rule 11572, deferring instead to the foreign market's usual conditions. 

And paragraph (j), Uniform Transfer Instruction Form, requires that a properly executed Uniform Transfer Instruction Form — set forth as Supplementary Material .01 — accompany securities presented for transfer.

FINRA Rule 11550 was amended by SR-FINRA-2010-030 effective December 15, 2010, by SR-NASD-91-13 effective November 1, 1991, and effective March 1, 1970 and December 1, 1972. Two selected notices are associated — 84-44 and 10-49.

FINRA Rule 11550 sits within the 11500 Delivery of Securities with Restrictions subsection of the 11000 Uniform Practice Code, immediately following FINRA Rule 11540's delivery under government regulations framework and immediately preceding FINRA Rule 11560's certificate of company whose transfer books are closed framework.

FINRA Rule 11550(a): The Foundational Requirement and Seller-Borne Expense Allocation

FINRA Rule 11550(a) establishes the rule's foundational principle — any registered security to be a good delivery must be accompanied by an assignment and a power of substitution (when such power of substitution is required under paragraph (g) of this Rule) conforming to the requirements set forth in Rule 11550 to 11574, inclusive.

This provision extends the good delivery framework this dictionary has traced through FINRA Rules 11510, 11520, 11530, and 11540 to registered securities specifically — a registered security, to constitute good delivery, must be accompanied by an assignment (the document effecting the transfer of the registered owner's interest to the new holder) and, in the circumstances paragraph (g) specifies, a power of substitution (an additional document this dictionary will examine below). Critically, these accompanying documents must themselves conform to the requirements set forth across the entire span of FINRA Rules 11550 to 11574, inclusive — meaning FINRA Rule 11550's own paragraphs (b) through (j) and the entire FINRA Rule 11570 cluster (FINRA Rules 11571 through 11574) collectively define what conformance requires.

The second sentence establishes the now-familiar burden-allocation principle this dictionary has observed throughout the Uniform Practice Code — any expense incurred through failure of a seller to meet these requirements shall be paid by the seller. This mirrors FINRA Rule 11340(b)'s seller-borne stamp tax allocation, FINRA Rule 11410(d)'s seller-borne shipment expenses, and FINRA Rule 11510's seller-borne temporary-to-permanent certificate exchange burden — in each case, the party delivering bears the cost of ensuring the delivery satisfies the applicable documentation requirements, rather than shifting that cost to the receiving party.

FINRA Rule 11550(b): Assignment On the Certificate or On Separate Paper

FINRA Rule 11550(b) establishes the two permissible forms an assignment may take — an assignment shall be executed on the certificate itself or on a separate paper, in which latter case there shall be a separate assignment for each certificate.

This provision recognizes two distinct documentary approaches to effecting an assignment. The first — execution on the certificate itself — involves the registered owner signing directly on the certificate's own assignment section, a feature commonly printed on the reverse of registered security certificates for precisely this purpose. The second — execution on a separate paper — involves a standalone assignment document, distinct from the certificate itself, which paragraph (d) will specify the required content for.

The in which latter case there shall be a separate assignment for each certificate qualifier applies specifically to the separate-paper approach — where a holder is transferring multiple certificates and chooses to use separate-paper assignments rather than executing assignments directly on each certificate, a distinct separate assignment document is required for each individual certificate being transferred, rather than a single separate-paper assignment attempting to cover multiple certificates at once. This one-assignment-per-certificate requirement for the separate-paper approach ensures that each certificate's transfer is documented by its own dedicated assignment instrument, maintaining a clear one-to-one correspondence between certificates and their assignment documentation.

FINRA Rule 11550(c): The Technically Correct Signature Standard

FINRA Rule 11550(c) establishes one of the most operationally exacting standards in the entire rule — the signature to an assignment or power of substitution shall be technically correct; i.e., it shall correspond with the name as written upon the certificate in every particular without alteration or enlargement, or any change whatever, except that "and" or "&" "Company" or "Co." may be written either way.

This technically correct standard demands an extraordinarily precise correspondence between the registered name on the certificate and the signature on the assignment or power of substitution — every particular, without alteration or enlargement, or any change whatever. The phrase without alteration or enlargement is notable for what it implies about the kinds of departures that might otherwise seem trivial but are nonetheless prohibited — enlargement suggests that even expanding an abbreviated name to its full form (or vice versa) would violate the technically correct standard, absent the specific exception the provision goes on to establish.

That specific exception — except that "and" or "&" "Company" or "Co." may be written either way — carves out precisely two categories of variation as acceptable: the conjunction and versus the ampersand &, and the word Company versus its abbreviation Co. For these two specific variations only, the signature may use either form regardless of which form appears on the certificate itself. No other variation — however seemingly minor — falls within this exception.

The rationale for this exacting standard relates directly to the function an assignment serves — an assignment is the instrument by which the registered owner directs the transfer of their registered interest, and the transfer agent or registrar processing that assignment must be able to verify that the person signing the assignment is, in fact, the registered owner (or duly authorized to act on the registered owner's behalf). A signature that deviates from the certificate's registered name — even in ways that might seem inconsequential to a casual observer — introduces ambiguity about whether the signer is truly the registered owner, ambiguity that the technically correct standard is designed to eliminate by demanding exact correspondence, subject only to the two narrowly-defined exceptions paragraph (c) establishes.

FINRA Rule 11550(d): Required Content for Detached Assignments

FINRA Rule 11550(d) specifies what a separate (detached) assignment — the separate-paper approach paragraph (b) contemplates — must contain: a separate (detached) assignment shall contain provision for the irrevocable appointment of an attorney, with power of substitution, and a full description of the security, including name of issuer, issue, certificate number, and amount (expressed in words and numerals).

Two distinct elements are required. First, provision for the irrevocable appointment of an attorney, with power of substitution — this is the mechanism by which the registered owner's assignment becomes operative for transfer purposes; rather than the registered owner personally appearing before the transfer agent to effect the transfer, the assignment appoints an attorney (in the legal sense of an attorney-in-fact, not necessarily a lawyer) with authority to act on the registered owner's behalf in effecting the transfer, with that appointment being irrevocable (the registered owner cannot simply revoke the appointment once the assignment has been executed and the certificate delivered) and including power of substitution (the appointed attorney can themselves appoint a substitute attorney — a concept paragraph (g) will elaborate further).

Second, a full description of the security, including name of issuer, issue, certificate number, and amount (expressed in words and numerals) — this content requirement ensures the detached assignment unambiguously identifies which specific security and which specific certificate it pertains to, consistent with the one-assignment-per-certificate principle paragraph (b) establishes for separate-paper assignments. The amount (expressed in words and numerals) requirement — requiring the amount to be stated both as written-out words and as numerical figures — provides a redundancy check against transcription errors or alterations, a documentary practice with parallels in other formal financial instruments where dual word-and-numeral amount expression serves as a safeguard against fraud or error.

FINRA Rule 11550(e): Joint Registration and the All-Signatures Requirement

FINRA Rule 11550(e) addresses certificates registered in multiple names — a certificate registered in the names of two or more individuals or firms shall be a good delivery only if signed by all the registered owners.

This provision establishes an unambiguous all-or-nothing requirement for jointly registered certificates — where a certificate's registration reflects two or more individuals or firms as registered owners, good delivery requires that all of those registered owners have signed the assignment (or power of substitution, where applicable). A signature from only some, but not all, of the registered owners would not satisfy paragraph (e)'s requirement, and the certificate would not constitute good delivery on that basis.

This all-signatures requirement reflects the nature of joint registration itself — where multiple parties are registered as joint owners of a security (whether as joint tenants, tenants in common, or under whatever specific form of joint registration applies), each registered owner holds an interest that, depending on the specific form of joint ownership, may require that owner's own consent for a transfer of the jointly-held security to be effective. Paragraph (e)'s requirement that all registered owners sign ensures that a transfer of a jointly registered certificate cannot proceed on the authority of only some of the joint owners, protecting the interests of any joint owner who has not consented to the transfer by signing the assignment.

FINRA Rule 11550(f): Alterations and Corrections Require Explanation

FINRA Rule 11550(f) addresses the scenario where an assignment or power of substitution has been altered or corrected after initial execution — any alteration or correction in an assignment or power of substitution shall be accompanied by an explanation on the original instrument signed by the person or firm executing the same.

This provision requires that any alteration or correction — whatever its nature — be accompanied by an explanation, with that explanation itself appearing on the original instrument and signed by the same person or firm who executed the original assignment or power of substitution. This requirement serves an evident anti-fraud and clarity function — an assignment or power of substitution that has been altered or corrected after its original execution presents an obvious opportunity for fraud (an unauthorized party altering the document's terms after the registered owner's original signature) or, even absent fraud, simple confusion about what the document's operative terms actually are. By requiring that any alteration or correction be explained, on the original instrument, by the same person or firm who executed it, paragraph (f) ensures that the transfer agent or registrar reviewing the document has both notice that an alteration occurred and an explanation, from the original signer, of what that alteration represents — preserving the evidentiary integrity of the assignment or power of substitution notwithstanding the post-execution change.

FINRA Rule 11550(g): The Power of Substitution and the Blank-Execution Chain

FINRA Rule 11550(g) addresses the power of substitution mechanism that paragraphs (a) and (d) have already referenced — when the name of an individual or firm has been inserted in an assignment, as attorney, a power of substitution shall be executed in blank by such individual or firm. When the name of an individual or firm has been inserted in a power of substitution as substitute attorney, a new power of substitution shall be executed in blank by such substitute attorney.

This provision establishes what might be described as a chain-of-blank-powers mechanism. When an assignment names a specific individual or firm as the attorney (the attorney-in-fact appointed under paragraph (d)'s irrevocable appointment provision), that named attorney must execute a power of substitution in blank — meaning the power of substitution document is signed by the named attorney but does not itself name who the substitute attorney will be, leaving that name blank to be filled in later, presumably by whoever comes to hold the certificate and assignment in the ordinary course of subsequent transactions.

The second sentence extends this chain — if a power of substitution itself names a specific individual or firm as substitute attorney, that named substitute attorney must, in turn, execute a new power of substitution, again in blank. This creates a potentially extending chain — attorney executes a blank power of substitution; if that blank power of substitution is later filled in naming a specific substitute attorney, that substitute attorney must execute their own new blank power of substitution; and so on.

The function of this blank-execution chain becomes clear when considered in light of the broader transfer mechanics paragraph (d) establishes — the irrevocable appointment of an attorney, with power of substitution, in the original assignment is what allows a security to change hands multiple times without each successive holder needing to obtain a fresh assignment directly from the original registered owner. Each holder in the chain, by virtue of holding the certificate together with the assignment and (where applicable) the executed-in-blank power of substitution, can effect a transfer to the next holder by filling in that holder's name as substitute attorney — and that next holder, in turn, must execute their own blank power of substitution to enable the chain to continue, under paragraph (g)'s second sentence. This blank-execution chain mechanism allows a single original assignment, executed once by the original registered owner, to support multiple successive transfers without requiring the original registered owner's involvement in each subsequent transfer.

FINRA Rule 11550(h): The Guarantee Requirement and Its Deliberately Unspecified Guarantor

FINRA Rule 11550(h) establishes a guarantee requirement with a notably flexible standard for who may provide that guarantee — each assignment, endorsement, alteration and erasure shall bear a guarantee acceptable to the transfer agent or registrar. It is not the intent of this paragraph (h) that a "New York," national securities exchange member or other specific guarantee is required; rather, it is the intent only that the guarantee be acceptable to the transfer agent.

The first sentence establishes the requirement itself — every assignment, endorsement, alteration, and erasure must bear a guarantee, with that guarantee's acceptability determined by the transfer agent or registrar. A guarantee, in this context, refers to a signature guarantee — a certification, typically provided by a financial institution, vouching for the genuineness of the signature on the assignment, endorsement, alteration, or erasure, providing the transfer agent or registrar with assurance that the signature is genuine and that the signer had the authority to execute the document.

The second sentence is a clarifying interpretive statement addressing what might otherwise be a natural assumption — that some specific, named category of guarantee (the rule's example being a "New York" guarantee, presumably referring to a signature guarantee from a New York-based institution, or a national securities exchange member guarantee) is required. Paragraph (h) explicitly disclaims any such specific requirement — it is not the intent of this paragraph (h) that any such specific guarantee is required; rather, it is the intent only that the guarantee be acceptable to the transfer agent. This leaves the acceptability determination to the transfer agent itself, without FINRA Rule 11550 imposing any particular categorical requirement on what kind of institution or guarantor must provide the guarantee — the transfer agent's own acceptance standards govern.

This deference to the transfer agent's own acceptability standards is notable for its flexibility relative to the highly specific requirements found elsewhere in FINRA Rule 11550 — paragraph (c)'s technically correct signature standard, for example, leaves essentially no room for variation beyond its two named exceptions. Paragraph (h), by contrast, explicitly avoids imposing any specific categorical guarantor requirement, instead trusting the transfer agent's own determination of what guarantees it will accept — a determination that, in practice, is shaped by the Securities Transfer Agents Medallion Program and similar signature guarantee programs that have developed within the industry, though FINRA Rule 11550(h) itself does not reference any such specific program by name.

FINRA Rule 11550(i): The Foreign Internal Securities Carve-Out

FINRA Rule 11550(i) establishes a significant carve-out from paragraphs (b) through (g) for a specific category of foreign securities — except for Canadian Securities, American Depositary Receipts, American Shares, New York Shares and similar securities, the provisions of paragraphs (b) through (g) of this Rule, inclusive, and Rule 11572 shall not apply to Foreign Internal Securities in registered form. In default of specific Rules in this Code, the usual conditions of delivery and transfer of Foreign Internal Securities in registered form in the foreign market where principally traded shall apply.

This provision distinguishes between two categories of foreign-connected securities. The first category — Canadian Securities, American Depositary Receipts, American Shares, New York Shares and similar securities — represents foreign-connected securities that, despite their foreign connection, are structured or traded in a manner sufficiently integrated with the U.S. market (or, in the case of Canadian securities, sufficiently proximate and integrated with U.S. practice) that FINRA Rule 11550's paragraphs (b) through (g) and FINRA Rule 11572 continue to apply to them in the ordinary way. This category connects directly to FINRA Rule 11140(b)(3)'s ADR and foreign securities provision examined earlier in this dictionary's coverage, which similarly singled out ADRs and foreign securities for distinct treatment within the ex-date framework.

The second category — Foreign Internal Securities in registered form, falling outside the first category's enumerated exceptions — is exempted from paragraphs (b) through (g) and FINRA Rule 11572 entirely. For this category, paragraph (i)'s second sentence establishes the governing standard: in default of specific Rules in this Code, the usual conditions of delivery and transfer of Foreign Internal Securities in registered form in the foreign market where principally traded shall apply. This is a deference provision — rather than imposing the U.S.-centric assignment, signature, power of substitution, and guarantee framework of paragraphs (b) through (g) on securities whose principal trading occurs in a foreign market with its own established conventions for registered security delivery and transfer, paragraph (i) defers to that foreign market's usual conditions, recognizing that imposing FINRA Rule 11550's U.S.-developed framework on securities principally governed by a different market's established practices could create friction or incompatibility without corresponding benefit.

The Foreign Internal Securities terminology itself — distinguishing securities that are internal to a foreign market from the enumerated categories (Canadian Securities, ADRs, American Shares, New York Shares) that represent various forms of cross-border integration with the U.S. market — reflects a recognition that not all foreign-connected securities present the same considerations, and that FINRA Rule 11550's detailed assignment and transfer framework is calibrated to securities trading within the U.S. market's own conventions, whether those securities are domestic or represent one of the enumerated cross-border-integrated categories.

FINRA Rule 11550(j) and Supplementary Material .01: The Uniform Transfer Instruction Form

FINRA Rule 11550(j) establishes the final documentary requirement — a properly executed Uniform Transfer Instruction Form must accompany securities presented for transfer — with a footnote confirming this form's origin: specifications for use of the Uniform Transfer Instruction Form are contained in the Final Report of the Banking and Securities Industry Committee entitled "Four Uniform Forms" dated December 22, 1971.

This confirms what this dictionary's FINRA Rule 11360 entry anticipated — the Uniform Transfer Instruction Form referenced in FINRA Rule 11100(d)'s CUSIP requirement is the third member of the trio of standardized 1971-era forms, completing the set alongside FINRA Rule 11210's Uniform Comparison Form and FINRA Rule 11360's Uniform Delivery Ticket Form. Supplementary Material .01 sets forth this form's structure — confirmed from the FINRA.org page as containing fields addressed to the transfer agent, requesting transfer of attached securities, with fields for the member's name, address, and I.D. number; security description; certification presented to transfer; quantity; denominations; taxpayer number; CUSIP number; control number; presentor; date; and the name in which the security is to be registered.

The form's CUSIP number field directly embodies FINRA Rule 11100(d)'s requirement, completing the pattern this dictionary has now confirmed across all three of the 1971-era Uniform Forms — the Uniform Comparison, the Uniform Delivery Ticket, and now the Uniform Transfer Instruction Form, each carrying the CUSIP number field that FINRA Rule 11100(d) mandates, and each corresponding to a distinct stage of the transaction lifecycle this dictionary has traced throughout its coverage of the Uniform Practice Code — initial trade confirmation, delivery, and now transfer of registered securities specifically.

Connection to FINRA Rules 11100, 11110, 11140, 11210, 11340, 11360, 11410, 11500, 11510, 11570 Through 11574, and 11580 Through 11581

FINRA Rule 11550 connects to FINRA Rule 11100(d) — whose CUSIP number requirement for the Uniform Transfer Instruction Form is embodied in Supplementary Material .01's CUSIP number field, completing the trio of 1971-era forms this rule's entry has now fully confirmed. It connects to FINRA Rule 11110's good delivery framework, within which FINRA Rule 11550 establishes the assignment, power of substitution, and transfer documentation requirements for registered securities specifically. It connects to FINRA Rule 11140(b)(3) — whose ADR and foreign securities provision parallels the enumerated exceptions (Canadian Securities, ADRs, American Shares, New York Shares) in FINRA Rule 11550(i)'s foreign internal securities carve-out. It connects to FINRA Rule 11210's Uniform Comparison Form and FINRA Rule 11360's Uniform Delivery Ticket Form as the other two members of the 1971 Four Uniform Forms trio. It connects to FINRA Rule 11340 and FINRA Rule 11410 as structural parallels for the seller-borne expense allocation principle FINRA Rule 11550(a) establishes. It connects to FINRA Rule 11500 as its parent series marker. It connects to FINRA Rule 11510's good delivery framing as the first in the sequence of good-delivery-disqualifying-condition rules within the FINRA Rule 11500 subsection that FINRA Rule 11550 now extends to registered securities' documentation requirements specifically. It connects directly and by explicit cross-reference to FINRA Rules 11571 through 11574 — the FINRA Rule 11570 cluster that paragraph (a)'s conforming to the requirements set forth in Rule 11550 to 11574, inclusive explicitly incorporates, and whose category-specific provisions for certificates registered in the names of corporations, firms, dissolved firms, and deceased persons or trustees will elaborate on FINRA Rule 11550's general framework for those specific registration-name categories — with FINRA Rule 11572 specifically exempted, alongside paragraphs (b) through (g), from application to most Foreign Internal Securities under paragraph (i). And it connects to FINRA Rules 11580 and 11581 — the limited partnership securities transfer rules that, as this dictionary's FINRA Rule 11500 entry discussed, represent a related but distinct registered-interest transfer framework operating alongside FINRA Rule 11550's corporate-securities-oriented assignment and power of substitution framework.

Examination Relevance and Key Takeaways

FINRA Rule 11550 is tested on the Series 7 and Series 24 examinations as the comprehensive assignment, power of substitution, and transfer documentation framework for registered securities — the general framework that FINRA Rules 11571 through 11574 elaborate for specific registration-name categories.

The key points to retain are these: FINRA Rule 11550(a) requires that registered securities be accompanied by an assignment and, when paragraph (g) requires it, a power of substitution conforming to FINRA Rules 11550 through 11574, with seller-borne expenses for non-conformance; FINRA Rule 11550(b) permits assignment execution on the certificate itself or on separate paper, with one separate assignment per certificate for the latter approach; FINRA Rule 11550(c) establishes the technically correct signature standard — exact correspondence with the certificate's registered name in every particular, with only "and"/"&" and "Company"/"Co." interchangeable; FINRA Rule 11550(d) requires detached assignments to contain provision for irrevocable appointment of an attorney with power of substitution, plus a full security description including issuer name, issue, certificate number, and amount in both words and numerals; FINRA Rule 11550(e) requires all registered owners' signatures for jointly registered certificates; FINRA Rule 11550(f) requires any alteration or correction to be explained on the original instrument by the original signer; FINRA Rule 11550(g) establishes the blank-execution chain for powers of substitution, enabling successive transfers without involving the original registered owner; FINRA Rule 11550(h) requires a guarantee acceptable to the transfer agent or registrar, explicitly without mandating any specific category of guarantor such as a "New York" or national securities exchange member guarantee; FINRA Rule 11550(i) exempts most Foreign Internal Securities in registered form — other than Canadian Securities, ADRs, American Shares, New York Shares, and similar securities — from paragraphs (b) through (g) and FINRA Rule 11572, deferring instead to the usual conditions of the foreign market where principally traded; FINRA Rule 11550(j) and Supplementary Material .01 require a properly executed Uniform Transfer Instruction Form, the third of the 1971 Four Uniform Forms alongside the Uniform Comparison and Uniform Delivery Ticket, embodying FINRA Rule 11100(d)'s CUSIP requirement; and the rule was amended December 15, 2010 through SR-FINRA-2010-030, by SR-NASD-91-13 effective November 1, 1991, and effective March 1, 1970 and December 1, 1972, with two selected notices — 84-44 and 10-49.
