S_AZ PASS-10 — Arizona consumer money-debt merits, ownership, assignment, and account proof

Research date: October 27, 2026. October 22 is the project baseline, not the verification date for this pass. The sources identified below were freshly accessed during this pass. Exact opening times for individual sources were not logged and are UNKNOWN.

The central finding is that Arizona’s proof requirements depend on the cause of action, the evidence offered, and the stage of the case. Contract liability, ownership of the particular obligation, admissibility of records, and correctness of the amount are separate questions. A document can satisfy one question while leaving the others unresolved.

Several distinctions materially affect this component:

• Arizona’s credit-card statute permits acceptance through specified conduct, including authorized use; a wet-ink signature is not universally required. The applicable agreement and disputed terms still matter.
• The statutory final-statement route concerns the amount in an uncontested credit-card action. A contested action requires the court to weigh the evidence.
• Assignment evidence must identify the obligation transferred and support the asserted transfer. Neither a portfolio-sale label nor a branded statement necessarily connects the particular account to the plaintiff.
• Business-record authentication, a hearsay exception, and sufficient proof of liability are distinct. A qualified witness need not have personally created every record, but possession of records and a conclusory assurance of reliability are insufficient substitutes for the required foundation.
• Arizona amended its summary-evidence rules effective January 1, 2025. An admissible Rule 1006 summary is different from a Rule 107 illustrative aid.
• Eldred is a memorandum decision, not published precedent. Its discussion of silence following a collection notice must be considered alongside the federal statutory prohibition against construing failure to dispute under §1692g as an admission of liability. The federal provisions were recovered in the official 2024 Code edition; later federal currentness remains expressly held.

These findings are supported by claims C003–C006, C023–C024, C030–C045, C059, C071, and C076–C079 below. Acceptance of credit card agreement+5

1. Causes of action and the elements that need proof

Cause-of-action and element matrix

The plaintiff’s proof burden does not become the defendant’s burden to disprove the debt merely because the plaintiff files for summary judgment. Allen reversed a creditor’s summary judgment because the creditor’s own showing was inadequate; it did not adjudicate that the debt could never be proved on remand. C058–C061. cases.justia.com+5

Identity, assignment, and account-linkage evidence matrix

These are evidence questions, not a universal list of mandatory document names.

Lesnick found the offered assignment insufficient because the purported transfer did not adequately identify the creditor relationship and obligation, and the evidentiary gap was not supplied by other proof. The Arizona Supreme Court quoted its identification principle again in Pointe 16 in 2025. Neither opinion establishes that every consumer debt must be proved through one prescribed form of bill of sale. C023–C025. law.justia.com+1

2. Complete source and access register

Source-status conventions

All accesses below occurred October 27, 2026.

• Fresh body: the identified substantive portions were read.
• Fresh partial: identified portions were read; the entire document or amendment chain was not.
• Index: navigation, currency, or discovery material; not a substitute for operative text.
• Reproduction: the court-authored opinion was read on a disclosed nonofficial host.
• Failed/discovery: no operative body was obtained through the stated routes.

For HTML sources, PDF page/index is not applicable. For PDFs, printed pages and zero-based PDF indices are supplied where established. A page number not established from the read material is not inferred.

2.1 Statutes and enactments

S001 section-access map — one compilation, 19 fresh section bodies

2.2 Promulgated rules and final orders

2.3 Judicial opinions

2.4 Federal text, currency indices, and unrecovered documents

2.5 Failed-route and recovery ledger

3. Published-case and posture register

The following are the actual cases read, not a required-case quota. The register distinguishes the court’s disposition from the substantive result it did not decide.

The two particularly useful current comparisons are Parker/Strong for the difference between a qualified foundation and mere possession, and Lesnick/Pointe 16 for assignment identification and the effect of actual transfer language. law.justia.com+3

4.3 Pleading, disclosure, summary judgment, trial, and defenses

4.4 Currentness, conditional models, and additional electronic-record clauses

5. Twenty distinct fictional postures

All actors and records below are fictional. None is an actual borrower, provider, account, or case assessment.

6. Four fully worked fictional models

M01 — Original-creditor account, disputed interest, and disputed fee

Actors: fictional Issuer O and Consumer X. Assumed governing framework: Arizona contract/card law applies; this is a contested action. No limitations or court-response clock is calculated.

Documents assumed for the positive arithmetic branch: an attributable agreement; records supporting the opening principal, purchases, return, and payment; an applicable term providing lawful 12% annual simple interest, actual/365, on the specified constant principal for the specified period. The $35 fee is separately disputed.

Fictional events

• January 1, 2026: supported opening principal $1,000.
• January 1: purchases $250 and merchandise return $50 are posted before the interest period begins.
• Interest runs from January 1 to January 31, excluding January 31: 30 elapsed calendar days.
• January 31: $250 actual payment is credited.
• For this example, the established payment allocation pays accrued interest first, then principal.
• A separate $35 fee is posted after that payment. Its authority is not stipulated.

Calculation

Plain text

Principal at start of interest period
= $1,000.00 + $250.00 − $50.00
= $1,200.00

Interest, before rounding
= $1,200.00 × 0.12 × 30 / 365
= $11.835616438...

Stipulated rounding: nearest cent, once at period end
Interest = $11.84

Payment allocated to interest = $11.84
Payment allocated to principal = $250.00 − $11.84 = $238.16

Principal after payment = $1,200.00 − $238.16 = $961.84
Remaining interest = $0.00
Claimed fee = $35.00

Claimed total = $961.84 + $0.00 + $35.00 = $996.84

Positive branch: if the terms, lawful applicability, records, and attribution are established, the interest arithmetic is supported. The fee still requires its own basis.

Adverse branch: if the offered agreement is the wrong version, or rate/base/period authority is missing, the legally supported amount is not established by inserting 12%. The unresolved formula is:

Plain text

$1,000 + $250 − $50 − $250 + I + F
= $950 + I + F

I is legally supported interest and F legally supported fees, neither assumed to be zero merely because the plaintiff’s offered proof is inadequate. No default statutory rate is supplied.

Burden and evidence: C002, C006–C008, C010, C012, C058–C060; model claims C081–C082. Sources: S001 §§44-7802–7805; S027 ¶¶16–20; S016 Rule 56(c)(5). This is not a determination that $996.84 or $961.84 is owed.

M02 — Two assignments, account inclusion, and servicing authority

Actors: fictional Originator O, Buyer A, Buyer B, Servicer S, and Consumer Y. Obligation identifier: fictional Q-104, used only within this example.

Balance before the sales

The stipulated supported January 31, 2026 balance is:

Plain text

Principal $1,000 + interest $40 + authorized fee $10 = $1,050

On February 5, O actually credits a $100 consumer payment. The stipulated lawful allocation is interest, then fee, then principal:

Plain text

Interest credit = $40
Fee credit = $10
Principal credit = $100 − $40 − $10 = $50

Remaining principal = $1,000 − $50 = $950
Remaining interest = $0
Remaining fees = $0
Remaining total = $950

No later interest or fee is included in this example’s claimed balance; that is a factual modeling assumption, not a rule that accrual stops on sale.

Chain/date/account-inclusion matrix

Separate cash ledgers

Plain text

Consumer ledger:
Opening debt $1,050 − actual credited consumer payment $100 = $950

Acquisition ledger:
A pays O $120 for the asset.
B pays A $80 for the asset.
Total acquisition consideration across the two sales = $200.

Consumer credit from those sale payments under the stipulated sale terms = $0.

The purchase consideration is paid for transferred assets; the example stipulates no accompanying consumer release. It is not an additional consumer charge and is not deducted from the $950 merely because the asset sold at a discount.

Procedural alternative: if O had already commenced an action before transferring its interest, Rule 25(c) would require separate analysis. The title chronology alone would not establish that O must be dismissed.

Held conclusions: validity of either transfer, account inclusion, enforceability of restrictions, S’s permissible party role, and any actual plaintiff’s entitlement.

Authorities: S028 pp. 602–603; S036 ¶¶13, 22–30; S016 Rules 17(a), 25(c); S001 §44-144. Claims C019–C029, C083–C084.

M03 — Foundation at summary judgment versus contested trial

Actors: fictional Buyer B, Consumer Z, and records witness W. Valid current title is stipulated solely to isolate the records issue; the certificate itself does not prove title.

Fictional records and dates

• Ordinary account entries are made during April–June 2026.
• The file contains 120 entries. Whether they are sufficiently voluminous and inconvenient to examine individually remains a court question; 120 is not a legal threshold.
• July 15: a litigation summary is prepared from those entries.
• July 20: W signs a declaration describing actual knowledge and the relevant recordkeeping practices.
• The parties contemplate a later summary-judgment motion and, if necessary, trial. No procedural filing date or notice period is calculated.

Foundation matrix

Ledger

All amounts below are principal; interest and fees are stipulated at $0 for the modeled period.

Plain text

Supported opening principal:       $800
New transactions:                 +200
Actual credited payments:         −250
Supported returns:                 −50
Claimed ending principal:          $700

Positive branch: with a complete supported opening balance and admissible records, the arithmetic totals $700. Liability, admissibility, and summary-judgment sufficiency still require their respective predicates.

Adverse branch: $400 of the opening $800 is merely an unexplained carried-forward figure.

Plain text

Documented-number subtotal:
$400 supported opening + $200 transactions − $250 payments − $50 returns
= $300

Unexplained opening component = $400
Claimed balance = $300 + $400 = $700

The $300 is not an adjudicated minimum recovery. Allocation, the cause of action, disputed transactions, and other liability facts can affect what the supported numbers prove.

At summary judgment, Rule 56 permits appropriately founded affidavits and admissible supporting material. At trial, the affidavit is not automatically a general hearsay substitute for testimony; an applicable certification, exception, stipulation, or other admissible route must support the offered evidence. Conversely, a properly established Rule 902(11) route can eliminate the need for live foundational testimony on the certified records.

Authorities: S008–S015; S016 Rule 56; S019; S027 ¶¶16–20; S029 ¶¶28–33; S035 ¶¶74–83. Claims C030–C049, C058–C064, C085–C086.

M04 — Settlement, provisional credit, reversal, replacement payment, and residual claim

Actors: fictional Creditor C and Consumer W.

Stipulated starting legal balance: principal $900, interest $60, authorized fees $40; total $1,000.

Stipulated settlement facts: a valid, authorized written pre-suit agreement freezes further additions and provides that $600 in cleared payments received by June 25, 2026 releases the remaining balance. This is an assumed existing agreement, not a drafted compliance form or a determination that any actual settlement has these effects.

Plain text

Net cleared consumer cash:
$200 + $400 − $400 + $400 = $600

Accounting residual before release:
$1,000 − $600 = $400

Conditional balance after the stipulated valid release:
$1,000 − $600 − $400 = $0

There is no duplicate credit for the reversed $400. The $400 release is not a cash payment.

Adverse branches

1. Receipt date or authority disputed: determine the actual recipient’s authority and the agreement’s payment/receipt terms. A processor’s possession or nonremittance does not by itself resolve whether the obligation was legally paid.
2. Replacement payment clears after the contractual condition: the arithmetic residual is $400, but waiver, modification, release language, and the parties’ conduct remain unresolved. No automatic collectible $400 is declared.
3. No valid release proved: a ledger showing $600 net receipts does not itself prove the claimed settlement defense.
4. Debt later assigned: assignment does not create a new fee or automatically erase an established release defense; the applicable transfer and notice facts still matter.
5. Discharge also asserted: bankruptcy scope and orders remain deferred. They are not inferred from this ledger.

The contractual date is fictional. No weekend, holiday, filing-calendar, or statutory deadline rule is being applied.

Authorities: S001 §44-144; S016 Rule 8(c); S008 Rule 408; S021 Rule 80(a) only if a disputed litigation agreement is actually implicated. Claims C026, C068–C070, C087–C088.

7. Source-currentness and interpretation reconciliation

8. Granular coverage and remaining-evidence table

8.1 Core coverage — 62 rows

Status: A = answered within stated scope/version; P = partial; H = held because necessary authority or facts are unavailable.

8.2 Deferred families — nine rows

9. Named hold register — 14 distinct holds

10. Contribution crosswalk — preserving prior review limits

The review-file statements above are user-provided provenance. I did not open or write coordinator files and do not claim a new review of the prior reports.

11. Count reconciliation and researcher self-check

Reconciled counts

Researcher self-check — not independent review

• I read the material statutory bodies, selected operative rule clauses and final amendments, and the relevant majority reasoning and dispositions identified in the source register.
• I did not read every page of the large rulebooks, every issue in the criminal opinions, every corrective rule order, or every later judicial treatment.
• I distinguished court-authored opinion text from host summaries, headnotes, added paragraph numbers, and a host’s “good law” badge.
• I did not count an authority merely quoted inside another opinion as a newly opened source.
• I treated Eldred as a memorandum and preserved both its record-specific reasoning and the §1692g(c) boundary.
• I kept current selected text, historical versions, future-effective Rule 111 language, the 2024 federal edition, and failed retrievals separate.
• The four models use disclosed fictional facts. Their arithmetic was checked; the stipulated interest rate, fee authority, ownership, records foundation, and settlement validity are not findings about any actual account.
• No actual person, entity, borrower, account, contract, property, license, live case, or docket was queried. No contact, filing, form submission, purchase, account change, website change, publication, new chat, or subagent was used for this pass.
• No local file write, independent review, comprehensive current-law certificate, actual collection permission, or state/parent acceptance is claimed.
