Motion to Extend Time to File Brief

Drafts a procedural motion requesting additional time to file a brief in an appellate court. Establishes good cause with specific facts and strict compliance with applicable rules of appellate procedure.

Prerequisites

Gather before drafting:

• Case caption — party names exactly as in appellate record, court name, case number
• Current deadline — date from court order or rule
• Brief type — opening, answering, or reply
• Party represented — appellant or appellee
• Extension history — prior extensions sought or granted
• Good cause facts — specific, verifiable grounds (conflicts, complexity, transcript delays)
• Opposing counsel's position — consent, non-opposition, opposition, or unreachable
• Applicable rules — jurisdiction's appellate procedure rules, local rules, standing orders

Document Structure

Section	Content
Caption	Full party names (exact appellate record format), unabbreviated court name, case number
Title	"Motion to Extend Time to File [Brief Type]"
Introduction	Moving party, current deadline, proposed new deadline, days requested
Argument	Good cause with specific facts; opposing counsel's position
Conclusion	Specific relief with exact new date
Proposed Order	Per local rules: case caption, new deadline, signature line

3. Establish good cause with concrete, verifiable facts (never conclusory statements)

5. Draft strongest argument first; descriptive headings; 3–5 pages max
6. Verify all dates, formatting, and representations (checklist below)
