A substitution of attorney form is the one-page court filing that officially changes who represents you in a pending case. To use it, you get the correct form from the court where your case sits, fill in the case caption and the identities of the outgoing and incoming attorneys, collect three signatures (yours, your former lawyer’s, and your new lawyer’s), file it with the clerk, and serve copies on every other party. Until that form is on file, your original attorney is still your attorney of record in the eyes of the court.
That status matters. The attorney of record receives every notice, deadline, and hearing date the court issues. A handshake agreement to switch lawyers does nothing for the court’s docket. If the form is not filed, your old lawyer keeps getting the mail and your new one gets nothing.
What the Form Contains
Every court uses its own version, but the fields are substantially the same. Federal courts use Form AO 154, “Consent Order Granting Substitution of Attorney,” and it is a useful template for understanding any state form you may encounter.1United States Courts. Substitution of Attorney The form asks for:
- The case caption: court name, district, plaintiff and defendant names, and case number.
- The name of the party whose representation is changing.
- A substitution statement identifying the new attorney by name and state bar number, and naming the withdrawing attorney.
- Contact information for the incoming attorney: firm name, address, phone, fax, and email.
- Three signature blocks: the party, the former attorney, and the new attorney.
- A line for the judge to sign and date an order approving the substitution.
The federal form carries a note that each new attorney entering an appearance must file a separate consent order, so if two or three lawyers from a new firm are joining the case, each files individually.2United States Courts. AO 154 Substitution of Attorney Form
States use their own forms, often mandatory Judicial Council versions, and they look different but collect the same core information. If you are firing your lawyer and representing yourself going forward (proceeding “pro se”), your own name and contact details go in the new-counsel fields, and you sign both as the party and as the incoming representative.
Getting and Completing the Right Form
Start with the court where your case is pending. The clerk’s office will point you to the required form, and most courts post fillable versions on their websites. A generic template pulled off the internet is not a substitute for your court’s specific document.
Fill every field. A missing bar number, an incomplete case number, or a blank signature line is a common reason clerks reject substitution filings. The three-signature structure is what lets this move through the court administratively, without a hearing. When the client, the outgoing attorney, and the incoming attorney all sign, the court generally treats the change as uncontested and processes it as paperwork.
Filing the Form
File the signed original with the clerk of the court handling your case. Many courts now require electronic filing. Federal courts use the CM/ECF system, and most state courts have adopted similar e-filing platforms. If your court still takes paper, deliver the original to the clerk’s window.
Filing fees for a substitution of attorney are uncommon in civil cases. Some jurisdictions charge a small administrative fee. Call the clerk’s office before you file so you are not turned away over a missing payment.
Serving the Other Parties
Filing with the court is only half the job. You also have to serve a copy of the filed substitution on every other party in the case, including all opposing counsel. That is how the other side learns where to send motions, discovery, and correspondence from here on.
The method depends on your court’s rules. In courts that use electronic filing, the e-filed document is often treated as automatically served on all registered attorneys. For paper filings, service is usually by mail or personal delivery. Many jurisdictions require that the person serving the document be at least 18 and not a party to the case.
After service, the person who served the document completes a Proof of Service listing who was served, when, and how. That Proof of Service gets filed with the court alongside the substitution. Without it, the court may not treat the substitution as complete.
When the Substitution Takes Effect
In most courts, the substitution is effective the moment it is filed, assuming the signatures are in place and a Proof of Service is attached. Some courts, including many federal districts, require a judge to sign the order before the change is official. The judge’s signature line on the AO 154 form reflects that step.2United States Courts. AO 154 Substitution of Attorney Form
Until the form is processed, the outgoing attorney is still the attorney of record. They still get the notices. They are still expected at any scheduled hearing. They still carry responsibility for any deadline that falls in the gap. That is the practical reason to file promptly after everyone signs.
Once effective, every pending deadline transfers immediately. Discovery responses, motion cutoffs, hearing dates: all of it belongs to the new attorney, or to you if you are now self-represented. A substitution does not automatically earn you an extension. Judges may grant more time when the switch was necessary and the new lawyer can show a specific deadline is impossible to meet, but it is not automatic.
If the Outgoing Attorney Will Not Sign
The consent form only works when all three signatures are available. If your former attorney refuses to sign off, the standard form is not an option. Instead, you or your new counsel file a motion to substitute counsel asking the judge to approve the change. If the attorney is the one who wants out and the client will not agree, the attorney files a motion to withdraw. Either motion requires a hearing and a declaration explaining why the voluntary route failed, phrased carefully to avoid disclosing privileged information.
A consent form can be processed the same day. A contested motion can take weeks, depending on the court’s calendar. That is the real difference between the two paths: the form is paperwork, the motion is litigation.
Fees and Your File After You Switch
The form changes who represents you. It does not resolve money or paperwork left over from the prior representation.
Any advance fees your former attorney has not yet earned have to be returned. Model Rule 1.16(d) of the ABA’s Rules of Professional Conduct requires a lawyer ending a representation to refund “any advance payment of fee or expense that has not been earned or incurred.”3American Bar Association. Rule 1.16 Declining or Terminating Representation Model Rule 1.15 requires those advance fees to be held in a client trust account and withdrawn only as earned.4American Bar Association. Rule 1.15 Safekeeping Property The ABA’s position is that a retainer labeled “nonrefundable” still has to be returned to the extent it was not earned. If your old attorney refuses, most state bars run fee arbitration programs that handle these disputes.
If the original fee arrangement was a contingency, the former attorney is still entitled to compensation for the reasonable value of the work they did before the switch, calculated under a theory called quantum meruit. They protect this right by filing a charging lien against any eventual settlement or judgment. In practice the two lawyers split the single contingency fee rather than each collecting a full percentage, so changing attorneys mid-case should not cost you more than the original fee percentage.
You are also entitled to your case file. Model Rule 1.16(d) requires the departing lawyer to surrender “papers and property to which the client is entitled.”3American Bar Association. Rule 1.16 Declining or Terminating Representation That includes pleadings, correspondence, discovery materials, and evidence. The standard is “promptly” and “upon request.” Most jurisdictions prohibit a lawyer from holding a client’s file hostage over an unpaid bill; the right to be paid does not override the client’s right to the file. Confirm with your new attorney whether they want the file digitally or on paper before the old firm sends it over.
