Federal law sets no specific number of days that a federal subpoena must be served in advance. Rule 45 of the Federal Rules of Civil Procedure requires only that the person receiving it have “reasonable time to comply.”1<\/a><\/sup>LII \/ Legal Information Institute. Federal Rules of Civil Procedure Rule 45<\/a><\/span> What counts as reasonable depends on what the subpoena asks for and who it lands on. A week may be plenty for a short deposition and clearly too little for years of records.<\/p>\n

That ambiguity cuts both ways. It frustrates people who want a bright-line answer, but it also gives you room to push back when the timeline is genuinely unworkable.<\/p>\n

The Reasonable Time Standard<\/h2>\n

The absence of a hard minimum is deliberate. A subpoena telling someone to show up and answer questions next week is a different ask than one demanding five years of financial records in that same window. A fixed notice period would be too short for complex document requests and unnecessarily long for straightforward testimony. The rule leaves courts free to judge each situation on its facts.<\/p>\n

Rule 45 also puts an independent duty on the party or attorney who issues the subpoena to take reasonable steps to avoid imposing an undue burden or expense on the recipient.1<\/a><\/sup>LII \/ Legal Information Institute. Federal Rules of Civil Procedure Rule 45<\/a><\/span> A court can sanction a party that ignores that duty and order them to pay the recipient’s lost earnings and attorney’s fees. The provision exists because subpoenas often land on people and businesses that have nothing to do with the underlying lawsuit.<\/p>\n

What Courts Look At When Deciding Whether the Notice Was Enough<\/h2>\n

When someone challenges the timing of a subpoena, judges don’t just count days on a calendar. They weigh the concrete factors that decide how hard compliance actually is.<\/p>\n
