promissory note
Enable an AI agent to recognise a promissory note, assess the evidence of its payment promise and current status, and identify actions requiring authority or further verification.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise a promissory note, assess the evidence of its payment promise and current status, and identify actions requiring authority or further verification.
A promissory note is a documentary instrument (historically a signed paper writing, now sometimes an electronic record) in which the maker undertakes an unconditional promise to pay a fixed or determinable sum of money to a named payee or to bearer, on demand or at a definite time, and which may circulate as a negotiable instrument if it meets the applicable statute of form.
It can be Inspect and transcribe the payment promise, signatures and operative terms while retaining links to their locations on the instrument.; Compare the presented note with copies, attachments and amendments to flag missing or conflicting content.; Construct a payment schedule or balance estimate when the terms and supporting payment evidence are sufficient.; Trace possession and claimed entitlement through documented transfers without treating possession alone as conclusive.; Record evidence of presentation, demand, payment, surrender or cancellation and identify unresolved consequences.; Identify prerequisites and authority needed before transferring, presenting, amending, cancelling or acting on the note..
Distinguishing features
Look for language attributing a promise to pay to the maker; an acknowledgement of debt alone does not establish that the document contains such a promise.
Determine whether the document expresses the maker's own payment promise or instead directs another party to pay, as a cheque or bill of exchange does.
Separate an instrument expressing a payment obligation from a receipt recording payment already made; later payment annotations may appear on the same note.
Determine whether the document is presented as a distinct payment instrument or merely contains repayment terms within a wider agreement.
Separate recognition as a promissory note from classification as negotiable, valid or enforceable; those classifications require additional evidence and applicable rules.
Scope
+ The physical instrument, its pages, attachments, markings and relationship to copies or digital representations
+ The maker's attributed promise to pay and the parties identified by the instrument
+ Principal, currency, interest provisions, payment timing and conditions expressed in the note
+ Signatures, execution evidence, amendments and document integrity
+ Possession, claimed entitlement, transfers, payments, cancellation and disputes affecting the note
- The complete underlying loan, sale or other transaction that occasioned the note
- The maker's overall financial condition and creditworthiness
- Ownership, valuation and enforcement of collateral securing the obligation
- Bank accounts, payment infrastructure and settlement operations
- Court proceedings, collection strategy and jurisdiction-wide legal doctrine
Characteristics
- Instrument embodiment
- paper instrument | electronic record | copy or image | uncertain An agent must distinguish the instrument being acted upon from a representation whose possession may have different consequences.
- Maker and signature attribution
- identified maker(s), attributed signatory or representative, supporting evidence and attribution uncertainty The payment promise must be connected to the person or entity said to have made it.
- Payee and claimed entitlement
- named payee, current possessor, claimed person entitled to payment and basis of each role The original recipient, physical custodian and person claiming payment may differ.
- Stated principal
- monetary amount and stated currency; record conflicting expressions separately It anchors the payment promise without being confused with the amount currently outstanding.
- Interest provision
- expressly interest-free | fixed rate | variable rate | other formula | silent | ambiguous Interest calculations require the actual provision, including any rate basis and calculation conventions.
- Payment timing
- on demand | single stated maturity | instalments | event-linked | ambiguous The timing provision determines which dates, events or demands must be evidenced before assessing whether payment is due.
- Document integrity
- no discrepancy observed | incomplete | alteration suspected | competing versions | not assessed Missing pages or changed terms can undermine interpretation and require investigation.
- Reconciled unpaid amount
- amount by currency and as-of date, with calculation basis, payment evidence and unresolved differences The face amount alone does not show the remaining obligation.
- Payment and discharge status
- not assessed | no payment evidenced | partly paid | full payment evidenced | discharge asserted | disputed Recorded payment, asserted discharge and an established legal conclusion must remain distinguishable.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 33 questions.
Instrument and payment promise Establishes what document is being modelled and what payment commitment it expresses.
A title or registry label cannot establish the substance or boundaries of the instrument.
Documentary boundary
Identifies the presented instrument and the material forming part of it.
Note and associated material
Record the note's embodiment, identifying marks, pages and attachments, distinguishing originals, representations and referenced agreements.
- Which pages, reverse-side markings and attached sheets are presented as part of this note? boundary
- What evidence identifies this item as an original instrument, an electronic record or a copy? provenance
Promise recognition
Examines the operative wording before assigning a legal classification.
Expressed payment commitment
Capture the words expressing the maker's payment promise and any qualifications or references that affect its interpretation.
- What exact wording expresses a promise by the maker to pay, rather than only acknowledging debt or ordering someone else to pay? definition
- Which conditions or references qualify the promise, and which merely describe the underlying transaction? boundary
Parties and execution Connects the payment promise to its attributed maker, recipient and execution evidence.
The agent needs evidence of who undertook the promise and in what capacity before attributing responsibility.
Promising and receiving parties
Separates the roles stated in the note from other participants in the transaction.
Maker and payee identification
Record each named maker and payee, the wording identifying the recipient of payment, and ambiguities in identity or role.
- Who is identified as making the promise, and what evidence resolves abbreviated or conflicting names? provenance
- To whom does the note say payment is to be made, including any order or bearer wording? definition
Signature and capacity
Examines attribution, representative capacity and execution chronology.
Execution evidence
Record signatures or other execution evidence, stated capacities, dates and places without assuming authenticity or authority.
- What evidence attributes each maker's signature or execution act to the identified person? provenance
- If someone signed for an entity or another person, what capacity is stated and what evidence supports that authority? provenance
- Which execution details remain unverified before the agent may rely on the attributed promise? action
Payment terms and triggers Captures what is promised, how amounts are determined and when payment is called for.
The note's state cannot be judged from principal or maturity alone when interest, instalments or triggering events apply.
Amount and interest
Preserves the monetary expressions and calculation provisions in the note.
Promised sum and calculation basis
Record principal, currency, interest and additional charges as written, flagging missing conventions or inconsistent amounts.
- What principal and currency are stated, and do words, numerals or different sections disagree? measurement
- What interest and charge provisions are expressed, including rate changes, accrual dates and calculation conventions? measurement
Maturity, demand and acceleration
Identifies the events and procedural evidence relevant to payment becoming due.
Payment timing and trigger evidence
Record maturity or instalment terms, demand provisions and any stated acceleration mechanism, separating contractual wording from verified effect.
- What dates, instalment schedule, demand or other events does the note specify for payment? definition
- What evidence shows that a relevant demand, notice, missed instalment or other stated trigger occurred? provenance
- What unresolved interpretation or applicable rule prevents the agent from determining the amount currently due? boundary
Custody, transfer and integrity Tracks where the instrument is, how claims to it arose and whether its operative content changed.
Physical access, a transfer record and entitlement to payment are different facts that must be examined together.
Possession and entitlement history
Traces custody and claimed rights without collapsing them into ownership.
Custody and transfer chain
Record the current custodian, claimed payment entitlement, endorsements, assignments and delivery evidence, including gaps or rival claims.
- Who currently holds the instrument, and on what documented basis does anyone claim entitlement to payment? provenance
- Which endorsements, assignments or delivery records connect the named payee to the current claimant, and where are the gaps? provenance
- What evidence and authority must be verified before an agent facilitates a proposed transfer or release of custody? action
Alterations and competing instruments
Examines changes, substitutions and uncertainty about which instrument governs.
Operative version and change evidence
Record amendments, erasures, replacements, missing originals and competing versions, preserving evidence of consent and chronology.
- Do available versions differ in amount, payee, maturity, signatures or other operative wording? measurement
- What evidence explains and authorises each change or establishes the relationship between an earlier note and a replacement? provenance
Performance, discharge and action Relates payment and dispute evidence to the note's remaining obligation and possible next actions.
A signed note may persist after payment, while cancellation markings or an asserted default may require corroboration.
Payments and discharge evidence
Reconciles performance and records the basis of any asserted discharge.
Remaining obligation and closure
Connect evidenced payments to this note, record allocation assumptions, and distinguish full payment from other asserted grounds of discharge.
- Which payments are evidenced as applying to this note, and how were they allocated among principal, interest and charges? measurement
- What supports any asserted discharge, including receipts, release terms, surrender or cancellation markings? provenance
- What unpaid amount can be supported as of a specified date, and which assumptions or discrepancies remain? measurement
Disputes and action prerequisites
Makes contested claims and dependencies visible before consequential action.
Claim status and permitted next step
Record asserted nonpayment, authenticity or entitlement disputes and the evidence, authority and applicable rules needed for a proposed action.
- Which claims about nonpayment, authenticity, entitlement or discharge are disputed, by whom and on what evidence? provenance
- Before presenting, demanding payment, amending or cancelling this note, what authority and procedural prerequisites must be established? action
- Which questions about negotiability, enforceability, time limits or remedies require jurisdiction-specific assessment? boundary
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

- Which of these standards and regulation hold for the sense of promissory note this model covers, and on what evidence? provenance
Real-world use
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- At a residential or commercial property closing the borrower signs a note (the debt) and a separate mortgage or deed of trust (the lien); the note is what is later sold, pooled, or enforced.
- Banks, finance companies, and private lenders take notes as the core evidence of a business or personal loan, often with a security agreement or guarantee attached.
- Startups issue convertible promissory notes to seed investors as a short-term debt that is expected to convert at a later equity round.
- U.S. federal student borrowers sign a Master Promissory Note that can cover multiple disbursements across years.
- Seller-financed real estate and equipment deals use installment or balloon notes in place of, or alongside, bank credit.
- Short-term corporate funding is often done with promissory notes that, when meeting commercial-paper market conventions, trade as securities.
- The paper (or authoritative electronic copy) is presented for payment, endorsed to a new holder, discounted to a bank, or produced in court as the claim on the debt.
- Historical banknotes began as promissory notes of a bank payable to bearer; modern currency has largely left that private-instrument regime.
- Which of these real-world use hold for the sense of promissory note this model covers, and on what evidence? provenance
Typical measurements
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Original principal (face amount) - Consumer and SME notes commonly 1e3-1e7 in the note's currency; public and intercompany notes range from small sums to billions; no inherent upper bound - currency units of the note
- Contract interest rate - 0 (interest-free or original-issue-discount notes) to the local usury or consumer-credit cap; many commercial notes sit near prevailing credit spreads (often low single digits to mid-teens percent per year) - % per year
- Tenor / stated maturity - Demand (no fixed date) through 30-90 day commercial paper, 1-7 year business notes, and 15-30 year residential mortgage notes - days or years
- Outstanding unpaid principal - 0 after payoff, up to the original face plus capitalized interest and recoverable costs - currency units of the note
- Payment frequency - On demand, or monthly (most consumer/mortgage), quarterly, or a single bullet at maturity - payments per year
- Which of these typical measurements hold for the sense of promissory note this model covers, and on what evidence? provenance
Failure modes and hazards
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Maker default, acceleration of the unpaid balance, and judgment or foreclosure on any collateral.
- Form defects (a conditional promise, an uncertain sum, or missing parties) that destroy negotiability or, in Geneva-system countries, validity as a note.
- Forged maker signature (no maker liability) or forged endorsement (breaks the chain of title).
- Alteration of amount, date, or payee after issue.
- Loss, theft, or destruction of the unique paper original; transfer to a holder in due course can cut off the maker's personal defenses.
- Payment to the wrong person after an unrecorded transfer, or double payment if a lost-note affidavit is abused.
- Usury, illegal-purpose, or consumer-protection violations that make the note unenforceable or limit recoverable interest.
- Use of fabricated 'bonded' or sovereign-citizen promissory notes as purported payment, which is a known fraud pattern and does not discharge the underlying debt.
- In consumer settings, holder-in-due-course status historically stripped borrowers of seller-misconduct defenses; many jurisdictions now restrict that outcome on consumer paper.
- Which of these failure modes and hazards hold for the sense of promissory note this model covers, and on what evidence? provenance
Regional variation
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- United States: UCC Article 3; 'I promise to pay' is enough; holder in due course and lost-instrument rules are heavily litigated; several states restrict or ban cognovit (confession-of-judgment) notes.
- United Kingdom and much of the Commonwealth: Bills of Exchange Act model; a note is a two-party promise, a bill is a three-party order; Inland and foreign notes still appear in older practice.
- Geneva Uniform Law countries (much of continental Europe and jurisdictions that copied it): the words 'promissory note' / 'billet à ordre' / equivalent must appear in the instrument's language; aval (guarantee on the instrument) is a distinctive practice.
- Naming: English 'promissory note'; French 'billet à ordre'; Spanish 'pagaré'; German 'eigener Wechsel' / 'Solawechsel' as distinct from a drawn Wechsel.
- Islamic-finance practice generally avoids interest-bearing notes and uses other documented payment undertakings instead.
- Electronic original notes (eNotes) are operationally established in U.S. mortgage channels via registry systems; many other jurisdictions still treat a wet-ink original as the unique instrument.
- Which of these regional variation hold for the sense of promissory note this model covers, and on what evidence? provenance
Neighbouring kinds and how to tell them apart
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Bill of exchange (draft) - A bill is an order by the drawer to a drawee to pay a third party (or the drawer); a promissory note is the maker's own promise to pay. Under UCC, a note is a promise and a draft is an order (UCC § 3-104).
- IOU / mere acknowledgment of debt - An IOU typically admits that a sum is owed without the unconditional promise-to-pay and statutory form that make a note; it may evidence a debt but is not, without more, a negotiable instrument.
- Cheque (check) - A cheque is a bill of exchange drawn on a bank and payable on demand, not a promise by the drawer in note form.
- Bond or debenture - A bond is typically a security issued under an indenture or statute to many holders, often with transfer on a register; a promissory note is a discrete instrument between named parties, even when a particular issue of notes is later treated as securities.
- Loan or credit agreement - The agreement sets covenants, conditions, and representations; the note is the separable payment instrument. One can have a loan agreement without a note, or a note with only implied loan terms.
- Mortgage or deed of trust - Those instruments create or convey a lien on property; they secure a note but are not themselves the promise to pay. Enforcement of the debt is on the note; enforcement against the land is on the mortgage.
- Banknote (paper currency) - A modern banknote is legal-tender currency issued by a monetary authority; historically it was a bank's promissory note to bearer, but it is no longer enforced as ordinary private paper.
- Convertible equity / SAFE - A SAFE is usually a contract right to future equity, not a debt instrument; a convertible note remains a promissory note (a debt) until conversion or repayment.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of promissory note this model covers, and on what evidence? provenance
Sources
- Uniform Commercial Code, Article 3 (Negotiable Instruments), especially §§ 3-104, 3-108, 3-109, 3-301 to 3-312, 3-401 to 3-420 - U.S. statutory definition of a note, negotiability requirements (unconditional promise, fixed or determinable sum, demand or definite time, to order or bearer), transfer, presentment, lost-instrument procedure, and liability of maker and endorsers.
- Bills of Exchange Act 1882, c. 61, Part IV (Promissory Notes), especially ss. 83-89 - Common-law statutory definition used in the United Kingdom and, with local adaptation, much of the Commonwealth: a note is an unconditional promise in writing made by one person to another, signed by the maker, engaging to pay on demand or at a fixed or determinable future time a sum certain in money to or to the order of a specified person or to bearer; also the distinction from a bill of exchange.
- Convention providing a Uniform Law for Bills of Exchange and Promissory Notes (Geneva, 7 June 1930), Annex I, Title II (Promissory Notes), arts. 75-78 - Civil-law uniform form requirements, including that the instrument must contain the term 'promissory note' in the language of the instrument, an unconditional promise to pay, the name of the person to whom payment is to be made, the signature of the maker, and related rules on aval, maturity, and recourse.
- United Nations Convention on International Bills of Exchange and International Promissory Notes (New York, 9 December 1988) - Attempted uniform regime for international notes (the words 'international promissory note' plus UNCITRAL Convention on the face); useful as a contrast because few states have brought it into force, so domestic UCC, Bills of Exchange Act, or Geneva rules still govern almost all notes.
What the second pass must settle
- Which existing Vercy models cover negotiable instruments or debt instruments, and should this entry link to or specialise one of them?
- Does this PHY / PHY.OBJ registry entry own only tangible notes, or also electronic promissory notes and their distinct control evidence?
- Which jurisdiction and applicable rules govern recognition, execution, transfer, negotiability and enforcement for each modelled note?
- How should the model represent several makers, accommodation parties or guarantees appearing on the note without absorbing neighbouring obligation models?
- What evidence standards should support conclusions about lost or replaced originals, disputed alterations, payment allocation and final discharge?
