A memorandum entry is a dated, narrative notation in an accounting ledger or a court docket that records a significant event without the usual debits and credits. In bookkeeping, it captures things like stock splits, method changes, and signed contracts that matter for the record but don’t yet move money. In federal and state courts, it is the clerk’s short log of each filing, order, and ruling in a case. Both uses do the same job: preserving a reliable history of events someone will need to reference later.
When Accountants Use a Memorandum Entry
Memo entries appear whenever something significant happens that won’t fit into a journal entry with balanced debits and credits. The most common trigger is a stock split. When a company runs a 2-for-1 split, total equity on the balance sheet is unchanged, so there is nothing to debit or credit. Under GAAP (ASC 505-20), the company notes in the ledger that the share count has changed and, if the stock carries a par value, that the par value per share has been adjusted. Without that notation, later readers see share counts that don’t match period to period with no explanation.
Changing an accounting method is another trigger. If a company switches from weighted-average inventory valuation to FIFO, the memo entry captures the date of the switch, the reason for it, and the new calculation approach. That bridges reporting periods so an auditor or a new controller understands why the numbers shifted rather than assuming an error.
Binding agreements that haven’t yet produced a cash flow also call for a memorandum entry. When a business signs a multi-year service contract but no money has changed hands, the commitment gets noted so management can track upcoming obligations. The entry won’t appear in the trial balance, but it flags the future liability or revenue stream. This is where recordkeeping gaps most often appear: companies forget to document commitments that don’t trigger an immediate payment, then scramble to reconstruct the timeline during an audit.
What the Entry Should Contain
Every memorandum entry starts with the exact date the event occurred. That date anchors the entry to a specific reporting period and determines which fiscal year it falls into for audit purposes. A date error can cascade into misaligned financial statements, especially when the event sits near a year-end boundary like a contract signed in late December.
After the date comes a plain-language narrative. It should identify who was involved, what happened, and why the entry has no dollar amounts. For a depreciation-method change, that means the old method, the new method, the effective date, and the reason for the switch. The entry should be self-explanatory five or ten years later, when whoever wrote it may no longer be with the company.
Unlike a standard journal entry, a memorandum entry has no columnar debits and credits. It sits in the general journal as a narrative block within the chronological list of transactions, which signals to any reader that the event is informational rather than financial. Because there are no numbers to balance, the entry doesn’t affect the ledger’s mathematical totals.
Authorization and Internal Controls
The absence of dollar figures might make memo entries look low-risk, but they still need oversight. An unauthorized or inaccurate memo can distort the narrative record of a company’s financial history, create confusion during audits, and mask the absence of entries that should have been recorded with real figures. Federal internal control standards call for segregation of duties: the person authorizing a transaction, the person recording it, and the person reviewing it should not be the same individual.
In practice, most organizations require a supervisory sign-off before a memorandum entry goes into the general journal. Larger companies build this into their accounting software, requiring a second user to approve memo-type entries before they become permanent. That review confirms the narrative is accurate, the date is right, and no one is using a memo entry to avoid recording a transaction that should carry debits and credits.
Holding Up at Tax Time and in Court
A memorandum entry alone does not satisfy IRS substantiation requirements. The IRS places the burden of proof on the taxpayer to substantiate every entry, deduction, and statement on a return, and it expects invoices, contracts, and receipts behind the numbers. The memo adds context; it works alongside those supporting documents, not in place of them. During an audit, memo entries often prove their worth by explaining anomalies that would otherwise raise red flags: a sudden change in depreciation, a large contract without matching revenue, a share count that doubled overnight. The IRS lets taxpayers choose any recordkeeping system that clearly shows income and expenses, so memo entries fit that framework as long as the underlying documentation exists.1Internal Revenue Service. Recordkeeping
The same entries can come in as evidence under the business records exception to the hearsay rule. Federal Rule of Evidence 803(6) admits a record of an act, event, or condition if it was made at or near the time by someone with knowledge, kept in the course of a regularly conducted business activity, and created as a regular practice of that activity. Authenticity is established through testimony from a custodian or qualified witness, or through a Rule 902(11) or (12) certification. The opposing party can still challenge the record if the source of information or the method of preparation suggests it isn’t trustworthy.2Legal Information Institute. Federal Rules of Evidence Rule 803 – Exceptions to the Rule Against Hearsay A memo authorized by a supervisor, created on the date of the event, and stored as part of a routine process is far more likely to survive that challenge than one written after the fact with no clear chain of custody.
Memorandum Entries in the Courts
Inside the federal judiciary, the same term means something different: the clerk’s official log of everything that happens in a lawsuit. Federal Rule of Civil Procedure 79(a) requires court clerks to keep a civil docket and enter each filing, order, verdict, and judgment chronologically with a case file number.3Legal Information Institute. Federal Rules of Civil Procedure Rule 79 – Records Kept by the Clerk These entries are brief by design. The rule calls for the nature of the paper filed or the substance of an order, not the full text.
Judges use docket entries to handle scheduling changes, grant routine extensions, or note oral rulings from the bench. When a judge moves a trial date or grants two extra weeks to file a response, a short docket notation makes that order official. These entries carry real weight. Failing to comply with a docketed scheduling order can draw sanctions under Rule 16(f), which authorizes any just order and requires the noncompliant party to pay reasonable expenses, including the other side’s attorney’s fees.4Legal Information Institute.

Docket Entries and the Appeal Clock
The most consequential thing a docket entry does is start the clock for filing an appeal, and this is where the difference between a docket notation and a formal judgment becomes critical. Under Federal Rule of Civil Procedure 58, most judgments must be set out in a separate document to count as officially entered.5Legal Information Institute. Federal Rules of Civil Procedure Rule 58 – Entering Judgment When a separate document is required, the judgment isn’t entered until both conditions are met: the clerk records it in the civil docket under Rule 79(a), and the judgment appears as a standalone document.
If the court or clerk never issues that separate document, a safety valve kicks in. After 150 days from the docket entry, the judgment is treated as entered anyway, and appeal deadlines run from that point.5Legal Information Institute. Federal Rules of Civil Procedure Rule 58 – Entering Judgment Missing this distinction can be fatal. An attorney who assumes the clock started on the docket-entry date rather than the separate-document date can file too early or too late. Waiting indefinitely for a separate document the clerk never produces, without watching the 150-day backstop, can mean forfeiting appeal rights.
For some orders, such as those deciding motions for a new trial or to amend findings, no separate document is required. The docket entry alone triggers the judgment, and appeal deadlines begin immediately.5Legal Information Institute. Federal Rules of Civil Procedure Rule 58 – Entering Judgment
