Stringent Superior Court Requirements
The Superior Court of Justice doesn't care how brilliant your argument is if your line spacing is wrong. I've watched well-reasoned, well-supported, perfectly-cited factums get bounced from the registry for the kind of typographic detail most lawyers haven't thought about since law school. If you've ever filed in Superior Court, you already know what I'm talking about.
This article is about the technical formatting rules that govern Ontario Superior Court filing — the unglamorous side of litigation that can sink a brilliant argument before a judge even reads it. We're going to walk through the most common rejection triggers, cite the actual Rules of Civil Procedure that govern them, and explain why getting the format right isn't optional. None of this is gatekeeping for its own sake. The court has rules because consistency matters in a system that processes thousands of documents a week. Your job is to comply.
The Cost of a Rejected Filing
Before we get to the rules: why does this matter?
Because a rejection isn't a polite suggestion to fix your formatting. It means:
- Your filing date isn't the date you thought it was. If you were filing on the last day of a limitation period, that's a problem.
- Your client finds out, because someone has to explain why the matter isn't moving.
- The registry staff who reject your document on Monday remember your firm on Tuesday.
- The motion judge eventually sees the corrected version — with the registrar's rejection sitting right there in the metadata.
A rejected filing is the most avoidable embarrassment in litigation. Let's avoid it.
Rule 4 — The Rule You Should Have Memorized
Rule 4 of the Rules of Civil Procedure governs the form of every document filed in a civil proceeding. It's not glamorous. It's not arguable. It's a checklist. Most rejections trace back to a violation of Rule 4 or its sub-rules. Here are the ten parts that matter most.
1. Line Spacing — 1.5, Not Single, Not Double
Rule 4.01 governs the format of documents, and the working convention is 1.5 line spacing for body text. If you're pasting from a Word doc with a different default, fix it before you file. The registry runs a fast visual check, and a double-spaced affidavit dropped into a 1.5-spaced motion record gets flagged.
2. Font — 12-Point Serif
The Rules require text in a 12-point font. The convention — and the reason every Ontario factum looks roughly the same — is Times New Roman or a similar serif typeface. Arial is permitted but reads poorly in long-form arguments. What's not permitted: 10-point text crammed in to beat a page limit. Registrars notice. Judges notice more. Set 12-point in your firm's style sheet once and never think about it again.
3. Margins — Don't Cheat the Page Limit
Standard margins are 1 inch on every side under Rule 4.01. Tightening margins to fit more text on a page is the oldest trick in the book and the easiest one to spot. The registrar opens your PDF, hovers over the page, and sees a half-inch left margin. Rejected. Don't try it.
4. Styles and Headings — Consistent Hierarchy
Headings must be clearly distinguishable from body text — typically bold, sometimes underlined for the highest level — but they have to be consistent throughout the document. Mixing bold-italic for one heading and ALL CAPS for another reads as careless. The court doesn't have a precise heading rule; it has a form rule that requires documents to be "easily readable." Inconsistent styles aren't easily readable.
5. Page Numbering — Bottom Centre, Sequentially
Every document must be paginated, with page numbers at the bottom (centre or right-aligned). Motion records, factums, and books of authorities all require sequential pagination across the entire document — not restarting at each tab or section. The cover page is sometimes counted, sometimes not, depending on document type. Check before you finalize.
6. The Backsheet — Form 4C, Every Time
Rule 4.04 requires a backsheet on every document filed in court (Form 4C). Most lawyers know this. Firms still get tripped up on the details: title of proceeding, court file number, document type, name of party, lawyer of record with LSO number, address, phone, fax (yes, fax, in 2026), email. Missing fields equals rejection. Use a templated backsheet you trust and copy it into every filing.
7. Motion Records — Tabbed Exhibits and an Index
A motion record under Rule 37 has a strict structure: an index page at the front listing every tab, followed by tabbed sections each containing one document or exhibit. Tabs must be numbered sequentially, the index must match the tab numbers, and every page must be paginated. If you've ever tried to assemble a 200-page motion record at 4 PM on a filing day, you already know the value of getting this right the first time.
8. Page Limits — Factums Are 30 Pages
Factums on a motion are limited to 30 pages under Rule 4.06.1, and many judges enforce shorter limits (often 20 pages) for chambers motions and short matters. Court of Appeal factums are also capped at 30 pages under Rule 61.11. Appendices, schedules, and authorities don't count toward the limit — but don't stuff arguments into appendices. Judges scoff at that. The page limit exists to discipline your argument. Edit ruthlessly. The best factums are 18 pages.
9. Confirmation Forms — 2 PM the Day Before
Under Rule 37.10.1, motions require a confirmation form filed by 2:00 PM on the business day before the motion is heard. Miss the confirmation deadline and your motion can be struck from the list. This isn't a document rejection — it's worse. You arrive at court ready to argue and discover you're not on the docket. Set a calendar reminder for every motion. Check it twice.
10. Filing vs. Service — Two Different Deadlines
A document is served when delivered to opposing counsel, and filed when accepted by the court. Each has its own rule. A motion record served on opposing counsel doesn't help you if it isn't filed with the court before the deadline. Make a habit of filing the moment service is effected — not the next morning.
The Drafter's Role
This is what drafters do all day. Format compliance is muscle memory at WeDraftIt — every document we deliver is built to the Rule 4 spec, paginated correctly, with a properly populated backsheet and tabbed exhibits where needed. We don't get rejections, because rejection is a failure of attention to detail, and detail is the entire point of the work.
If you'd rather spend Tuesday morning preparing for argument than debugging your line spacing, that's the trade we exist to make.
Try It on Your Next Filing
Submit your next motion record, factum, or affidavit through WeDraftIt. You'll get a flat-fee quote within the day. Approve it, and we'll deliver the finished document — Rule 4 compliant, paginated, backsheet filled in, ready to file — by your deadline.
