Changing Your Firm's Mailing Address Smoothly

October 19, 2026

Moving your firm's mailing address is one of those administrative tasks that looks simple until you're in the middle of it. A missed notification can mean a court filing goes to the wrong place, a client's check gets lost, or a bar notice never reaches you. Getting ahead of it with a clear plan saves a lot of headaches later.

Before you send a single notice, pull together every place your current address appears. That list is almost always longer than attorneys expect.

Courts and Active Cases First

For any matter with pending filings or upcoming deadlines, file a notice of change of address promptly. Most courts have a specific form or procedure for this. Check the local rules for each court where you have active cases, because the requirements vary. Federal courts, state trial courts, and appellate courts often handle this differently, and some have electronic filing procedures that make it straightforward while others require a paper notice served on opposing counsel.

Opposing counsel on active matters should receive written notice at the same time or before you update the court record. Keep a copy of every notice you send.

Your State Bar Registration

Bar associations require current contact information for their member records. The update process is usually done through your member portal, but double-check whether your state bar also requires a separate mailing address for correspondence versus your address of record. Your state bar's own rules govern what qualifies and what has to be kept current, so review those rules directly rather than relying on any general guidance.

If you practice in more than one state, update each bar separately.

Clients, Past and Present

Active clients should hear from you directly, not discover the change when a letter bounces back. A short letter or email works fine. Include the effective date of the change, your new address, and a reminder that all other contact information stays the same.

For closed files, reasonable practice is to send notice to any client you've represented in the past few years, particularly those who might send a document or referral your way. You don't need to reach back a decade, but use judgment about who is likely to still have your address in their contacts.

Agencies, Vendors, and Recurring Contacts

This part of the list tends to grow as you go. Common ones attorneys overlook:

  • The IRS and state tax agencies (your firm's EIN correspondence)
  • Professional liability insurance carrier
  • Legal research and software vendors
  • Bar association sections and publications
  • Continuing legal education providers
  • Any court-appointed panel or pro bono program you participate in
  • Banks and financial institutions holding firm or trust accounts

Your IOLTA or trust account bank is especially important. Correspondence about those accounts should never go astray.

Your Public-Facing Materials

Update your website, your email signature, Google Business Profile, Avvo, Martindale, and any directory listings where your address appears. Clients and potential clients search for attorneys online constantly, and an outdated address on a directory listing creates confusion and can undermine trust.

If your letterhead, business cards, or contract templates have the old address printed on them, plan to update those before the next time you use them.

Give Yourself a Transition Window

If possible, arrange for mail at your old address to be forwarded for a period after the change. That buffer catches anything that slips through, whether it's a court that didn't update its records quickly or a vendor working from an old invoice.

A professional address with same-day mail scanning, like the service MailScans provides at its Los Angeles, Beverly Hills, Santa Monica, and Philadelphia locations, can make this kind of transition easier to manage. Every piece of mail that arrives is scanned into a secure portal the same day, so nothing waits on a pile somewhere while you're in court or traveling.

The change itself doesn't have to be disruptive. A good checklist and a few days of focused follow-through gets most firms fully transitioned without anything falling through the cracks.
