What is Slip Rule?
The slip rule allows courts to correct accidental errors, such as clerical mistakes or omissions, in orders without requiring a lengthy appeal. In New South Wales, this is governed by r 36.17 of the Uniform Civil Procedure Rules 2005; in the Federal Circuit and Family Court of Australia (FCFCOA), by r 10.13 of the Family Law Rules 2021. A similar federal provision appears in r 39.05 of the Federal Court Rules 2011. This simple but important mechanism ensures that judgments accurately reflect the court’s intentions. Whether it’s a typo or a missing detail, the slip rule gives parties a practical way to fix errors quickly. It is a useful tool in any legal process, and a party’s legal representative should always consider it before committing to a full appeal.

Slip Rule Applications in Property Settlement Disputes
Infamily law matters, particularly property settlement disputes, the slip rule can correct mistakes in financial or asset division orders without altering the substance of the settlement.
Many of us may not realise how often unintended errors can occur in complex legal documents. This is especially relevant in litigation contexts like property settlement disputes or when a judge erred by failing to record evidence properly. The slip rule offers reassurance that minor mistakes won’t stand in the way of a fair outcome. If we’re dealing with a court order that doesn’t accurately reflect the actual court ruling, understanding how the slip rule works can save us time, effort, and stress on family law matters.
A Deeper Understanding of Slip Rule in Family Law Matters

Occasionally, an error arising from a typo can be critical, for example, an accidental omission of a party’s graduate diploma reference or when children’s living arrangements are recorded incorrectly. The slip rule plays a crucial role in our legal system by enabling family courts to rectify certain errors in orders or judgments promptly and effectively. Understanding its definition, origins, and how it applies helps us see its importance in ensuring accuracy and fairness in legal processes.
Navigating Civil Procedure Rules and the Slip Rule
The slip rule is a legal provision that permits a family court to correct clerical errors, accidental slips, omissions, or typographical mistakes found in court documents, orders, or judgments under reasonable grounds. There are no proposed amendments to this rule at present, which means that a correction can occur even after a court order has been finalised, as long as the change is made to reflect what the court intended at the time the original decision was made.
Its main purpose is to ensure that legal documents accurately represent the true intentions of the court. By using the slip rule, we avoid unnecessary appeals or repeated hearings based solely on minor inaccuracies in legal practice. It provides a practical method to address mistakes that do not go to the merits of the case but could cause confusion or injustice if left uncorrected.
Types of errors commonly corrected under the slip rule include misspelled names, wrong dates, or accidental omissions in the text of an order. However, this rule does not allow for substantial changes to the judgment itself, only for correcting mistakes that are accidental.
Origins in Australian Law

In Australia, the slip rule has been enshrined in various court rules and legislation. The former Family Law Rules 2004 r 17.02 and the current FCFCOA r 10.13 specifically address its use in family law matters, allowing judges to vary orders to fix accidental errors in family law proceedings. Other courts (e.g., Federal Court Rule 39.05; state courts under UCPR Rule 36.17) possess the same power. The concept originates from the long-held principle that courts should have the power to accurately record their intentions without undue difficulty, not just in family courts.
This authority has been recognised by common law for decades and now operates under clearly defined statutory frameworks. Courts can exercise the slip rule either sparingly by their own initiative or after application by a party.
Relevant rules and sections of the Slip Rule in family law proceedings include Rule 10.13 of the Federal Circuit and Family Court of Australia Rules 2021, as well as corresponding provisions in district and supreme court rules. These ensure a uniform approach to correcting errors across Australia’s family law system.
Identifying and Correcting Errors in Court Orders
Understanding the structure and terminology of court orders helps parties pinpoint mistakes eligible for correction under the slip rule, ensuring accurate and enforceable directives.
Court orders are formal directives issued by a judge. Understanding their structure and wording helps parties identify and pinpoint errors for correction under the slip rule.
The slip rule applies in both civil and criminal courts but is most frequently used in civil and family law contexts.
Key features of its scope include:
- The authority to correct court orders and judgments for clerical or accidental mistakes.
- The limited nature of corrections: only errors that do not affect the substantive intention or reasoning of the court can be changed. We distinguish between mistakes that make a real difference to the substance of a judgment and those that are mere slips.
- The ability to make corrections promptly, either upon request from the parties or by the court acting on its own initiative. However, courts warn that liberal use could encourage carelessness in drafting.
Importantly, we cannot use the slip rule to revisit or reconsider judicial decisions or to alter findings of fact or law. Instead, it maintains the integrity of orders by ensuring they accurately document the decisions made. This makes it a practical tool for both litigants and courts, reducing delays and unnecessary disputes over technical mistakes.
Types of Errors Addressed by the Slip Rule
The slip rule primarily covers specific types of mistakes that occur in legal documents, particularly those made by oversight or simple errors. These include issues such as clerical mistakes, accidental slips, and omissions that may affect a court order or judgment.
Clerical Mistakes

Clerical mistakes are errors made when recording or drafting a legal order. This can involve incorrect spelling of names, numbers, or dates or other transcription mistakes made during the preparation of a formal judgment or order. Clerical mistakes can even involve academic credentials, such as a practitioner’s graduate diploma being spelled incorrectly on an order.
We often encounter clerical mistakes, such as inserting the wrong date or leaving out a middle initial in a party’s name. These mistakes are usually obvious and are not related to the substance of the decision. Their correction does not change the legal effect of the order but ensures the record accurately reflects what was intended.
Correcting such mistakes under the slip rule is straightforward. Courts typically expect anyone noticing these errors to promptly notify them so the order can be amended without delay. Examples include:
- Typographical errors in parties’ names
- Misstated addresses or dollar amounts
- Transcription errors transferring oral judgments into writing
Accidental Slips and Omissions
Accidental slips and omissions include mistakes, where something intended to be included in the court record, was left out or recorded incorrectly by oversight. These errors can range from omitted words essential for clarity to the accidental exclusion of key procedural directions. We see accidental slips when, for example, a sentence is partially missed during dictation or a key clause is left out when typing a judgment.
Such omissions are not deliberate and do not involve legal arguments or reconsideration of the case outcome. The slip rule allows the court to add or restore what was unintentionally omitted. Not all omissions qualify; only those simple, accidental errors that do not reflect a change in legal reasoning. For example, forgetting to include a specific date for an event to occur, or accidentally skipping a key condition in the final order.
Procedures for Correcting Errors
Application Process

To correct an error under the slip rule, we need to submit a Notice of Motion to the relevant court. This document must precisely state the nature of the supposed error in the order, such as a clerical mistake or an omission by the scribe or registrar. Applicants or their counsel should speak directly with the registrar to facilitate swift correction, often on short notice.
We should include a detailed description of the original order, the error at issue, and the language we propose for the correction. Supporting documents, including the order itself and any correspondence about the mistake, may strengthen our application. While parties often engage in pre-action procedures, using the slip rule can avoid the need to revisit earlier steps.
Typically, these applications are made without formal hearings. However, some circumstances may require notifying the other parties involved. The goal is to present the issue efficiently so the court can make a prompt decision.
Court’s Consideration
Once our application is submitted, the court or registrar examines whether the error qualifies under the slip rule. The key is that the mistake must be accidental, such as a clerical error by a scribe, rather than a matter of substance or judgment. The court’s own opinion determines whether the error is so trivial that no person would doubt the intended meaning.
The court assesses whether the correction aligns with its original intention and does not alter the substance of the decision. If the registrar identifies that the slip or omission is clear, they can issue a corrected order accordingly.
The court will also ensure all parties are treated fairly. If the error is significant or contested, the judge may direct further submissions. Ultimately, the corrected order replaces the original only in respect of the specific error addressed.

Limitations and Exceptions
Correcting orders under the slip rule is not always straightforward. There are restrictions based on the legal context, who is present, and the scope of the court’s authority.
Implied Power of the Court
Courts have an implied power to correct accidental slips, such as clerical mistakes, in their own orders. This power ensures that the intention of the court is accurately reflected in the final orders. However, the slip rule does not allow us to alter the substance or intent of the judgment.
If a party seeks to use the slip rule to revisit a contentious issue or reconsider an order’s merits, the court generally must refuse. Our corrections must be limited to errors such as typographical mistakes, arithmetic errors, or accidental omissions. When a proposed correction would change the meaning or outcome, an appeal or rehearing is usually required instead.
The implied power is discretionary, meaning the court may refuse to make a correction if it considers it inappropriate due to later events or changes in circumstances. This power must be exercised sparingly to preserve the finality of judgments.
Criminal Proceedings Restrictions
The slip rule’s use in criminal matters is restricted. The High Court in Achurch v The Queen (2014) 253 CLR 141 explains the rule cannot be used to reopen a sentence except for obvious clerical slips; more serious errors must proceed under the Crimes (Sentencing Procedure) Act 1999 (NSW) s 43. Unlike civil proceedings, criminal cases have additional safeguards due to the impact on the accused’s rights and liberty. We cannot amend criminal orders via the slip rule to change convictions, sentences, or substantive aspects relating to guilt or innocence.
Only minor clerical errors in the official record—such as names, dates, or formal details—can be adjusted. Any attempt to substantially modify an order in criminal proceedings would generally require a formal appeal or application for review.
This approach ensures that the rights of criminal defendants are protected and that any significant changes to orders go through proper legal channels.
Absence of a Party
When a party is absent during the correction of an order, the court must exercise caution. The slip rule should not be used to make amendments that adversely affect a party who was not present or had no notice of the change. Procedural fairness requires all parties to have an opportunity to be heard before an order is made, especially if their interests are affected.
If an amendment must be made in the absence of a party, the court may defer the correction until the affected party is notified or has the chance to respond. In exceptional circumstances, urgent minor errors may be corrected, but the party absent should be promptly informed.
We need to ensure that no party is unfairly disadvantaged by administrative corrections carried out without their knowledge or input.
Notable Cases and Practical Examples

The slip rule is widely applied in Australian courts to correct accidental errors in judgments and orders. Its practical use is particularly evident in family law and civil matters, where minor mistakes can have significant effects if left unaddressed.
Common Scenarios
Courts often employ the slip rule to resolve typographical errors, misstatements, or accidental omissions in court judgments and orders. In family law, a frequent example is the correction of a party’s name or a superannuation fund reference that was mistakenly recorded.
For instance, in a custody dispute where determinations about where children live impacted access, a clerical error regarding the mother’s living arrangement with the children was corrected to reflect the court’s true intent, ensuring stability for the children and fairness to the father.
Mistakes such as transposing figures or referencing the incorrect clause in an order are also frequently rectified under the slip rule. We also see its use when an order fails to reflect an agreement actually reached between parties, with the amendment being made to align the record accurately with the real intentions of the court.
Below is a quick overview:
| Scenario | Typical Correction |
| Typographical error | Correct spelling, numbers, or names |
| Misstated amount | Amend dollar figures |
| Incorrect clause | Substitute correct clause |
| Omitted provision | Insert missing order term |
Role of Mark and Notation
Accurate marking and notation are essential when invoking the slip rule. The court must clearly identify where the error is present in the judgment or order. This often involves referencing the specific page, paragraph, or order number that contains the mistake.
When we apply the slip rule, we use annotations in the court record to document both the original error and the correction made. This transparent process ensures traceability and supports the proper administration of justice. Notations are important for both historical accuracy and the practical enforcement of judgments by the parties affected.
In each case, correct documentation helps prevent confusion. If a mark or notation is unclear, further disputes can arise. Our adherence to precise notation practices directly supports the integrity and reliability of the court’s records.
