How to Insert and Customise Legal Outline Numbering in Microsoft Word Using AUTONUMLGL Fields

Legal agreements, commercial contracts, statutory filings, and judicial briefs demand strict, consistent outline numbering across clauses, subclauses, and subsections. While Microsoft Word provides standard multilevel list galleries, numbered lists can drift, misalign, or restart unexpectedly when copying and pasting clauses across different template styles. To maintain robust, uncorrupted sequential numbering across complex legal documents, Microsoft Word includes the specialised AUTONUMLGL (Automatic Numbering Legal) field code.

In this guide, you will learn how to insert AUTONUMLGL field codes, convert Roman numerals to Arabic legal digits, configure punctuation formatting, and update legal outlines dynamically in Microsoft Word.

Understanding the AUTONUMLGL Field Code

The AUTONUMLGL field is part of Word’s built-in outline numbering field family, alongside AUTONUM and AUTONUMOUT. However, while AUTONUMOUT follows standard outline formats that mix uppercase Roman numerals (e.g., I, II, III) with letters and Arabic digits, AUTONUMLGL forces all higher-level outline headings into standard Arabic digits (1, 1.1, 1.1.1, 2, 2.1).

Key properties of the AUTONUMLGL field include:

• Outline Style Dependency: It links directly to the heading styles applied in your document (Heading 1 through Heading 9).
• Arabic Conversion: Even if your Heading 1 is styled as “Article I” or “Section IV”, AUTONUMLGL suppresses the Roman numeral and outputs clean Arabic numerals (e.g., 1.1 instead of I.1).
• Independent Flow: It operates independently of the Ribbon’s multilevel list gallery, making contracts immune to list corruption when merged or collaborated on across multiple users.

Syntax and Optional Switches

The field syntax for legal outline numbering follows a simple structure:

{ AUTONUMLGL [Switches] }

Word supports optional switches to control trailing delimiters:

• \e: Formats the legal number without a trailing period (e.g., outputs 1.2 instead of 1.2.). This is essential when typing your own custom punctuation or parenthetical enclosures.
• \* MERGEFORMAT: Preserves explicit font and character formatting applied to the field when updating.

Step-by-Step: Inserting AUTONUMLGL Fields Manually

You can insert legal outline fields directly anywhere inside a paragraph using Word’s field shortcut keys:

1. Position the cursor at the very beginning of the legal clause or paragraph where the number should appear.
2. Press Ctrl + F9 (or Cmd + F9 on macOS) to insert a pair of curly field brackets.

   {  }

   Note: You cannot type standard curly brackets on your keyboard; they must be created via the field key combination.
3. Inside the brackets, type AUTONUMLGL or include the switch:

   { AUTONUMLGL \e }

4. Press F9 (or right-click the field and select Update Field) to evaluate the field code. Word immediately renders the sequential outline number.
5. Add a space or a tab character after the number before typing the clause title or agreement text.

Inserting AUTONUMLGL via the Word Ribbon Interface

If you prefer using the graphical user interface rather than keyboard combinations:

1. Navigate to the Insert tab on the Word ribbon.
2. In the Text grouping, click the Explore Quick Parts icon and select Field….
3. In the Categories dropdown menu, choose Numbering.
4. From the Field names list, select AutoNumLgl.
5. Under Field options, check the box for Separator character if you want to omit the trailing period, or select your preferred format.
6. Click OK to place the field into the document.

Configuring Document Heading Styles for Legal Numbering

For AUTONUMLGL to accurately calculate multi-level legal tiers (such as 2.1.4), the paragraphs preceding the clause must utilise built-in heading styles (Heading 1, Heading 2, Heading 3):

• Apply Heading 1 to your primary contract sections (e.g., Definitions, Obligations, Term & Termination).
• Apply Heading 2 or body paragraphs containing AUTONUMLGL under Heading 1. Word detects that the clause belongs inside section 1 and assigns it 1.1, 1.2, and so forth.
• If a paragraph under Heading 2 contains another AUTONUMLGL field at a deeper indentation level, it dynamically increments to 1.1.1.

Toggling Field Codes and Batch Updating

When reviewing documents with extensive field codes, you can switch between the evaluated numbers and raw field code formulas:

• Toggle Current Field: Click the number and press Shift + F9.
• Toggle All Fields Globally: Press Alt + F9 (or Option + F9 on Mac) to view all underlying field codes across the entire document.

When you insert, move, or delete clauses, Word fields do not always recalculate instantaneously in real time. To refresh all numbers across a 50-page legal agreement:

1. Press Ctrl + A to select the entire document.
2. Press F9. Word immediately recalculates all AUTONUMLGL fields, re-sequencing every clause and cross-reference perfectly without gaps.

Troubleshooting Common Numbering Glitches

If your legal numbers show unexpected sequences, check the following resolutions:

• Numbers Reverting to 1: If numbering resets unexpectedly, verify that an intervening blank line does not have an unintended Heading 1 style applied to it. Reset empty lines to the Normal style.
• Double Periods in Output: If your document displays numbers like 1.1.., your field code is omitting the \e switch while you also manually typed a period after the field. Either remove the typed period or change the field to { AUTONUMLGL \e }.
• Field Prints as Syntax Text: If Word prints { AUTONUMLGL } onto paper or PDF exports instead of numbers, navigate to File > Options > Advanced, scroll down to Print, and uncheck Print field codes instead of their values.
