Requesting an ALDF Amicus Curiae Brief

request an amicus brief

Thank you for your interest in having ALDF file an amicus curiae (“friend-of-the-court”) brief.

For more than three decades, ALDF has been fighting to protect the lives and advance the interests of animals through the legal system. To that end, ALDF authors amicus briefs on a broad range of topics relevant to the animal protection movement, assisting state and federal courts across the country.


ALDF may participate in a case as amicus curiae if the case concerns an issue of substantial interest to the animal protection movement and filing an amicus brief is feasible.

ALDF files an amicus brief only if we believe that we are able to represent ALDF’s position more effectively than the parties or that we can provide perspective, expertise, or information that would not otherwise be available, or when the court may be interested in ALDF’s position on an issue. ALDF will not submit a brief that simply repeats the arguments advanced by a party.

ALDF authors amicus briefs in our name, and not in the name of a party or of another entity.

ALDF files amicus briefs in both civil and criminal cases. Information about additional assistance with criminal prosecution may be found here. In some instances, ALDF is able to assist with aspects of litigation. For information about assistance with litigation, please contact ALDF’s Pro Bono Program at However, please note that ALDF generally does not fund litigation.

Your Obligations

ALDF must comply with the court’s filing deadlines and the full process of filing an amicus brief may take months, so it is important that you request an amicus brief as early as possible. Before contacting ALDF, please consult the court rules on the timing of amicus briefs to determine whether there is enough time to organize an amicus effort.

ALDF often receives pro bono assistance with drafting and filing amicus briefs. Please attempt to locate an attorney who can help ALDF with the requested amicus brief. At a minimum, please locate an attorney in your state who would file the brief and accompanying motion for leave to file the brief.

Process for Reviewing Requests

ALDF regularly reviews completed requests for amicus briefs. Although we regrettably can’t respond to every request we receive due to volume, we may contact the requestor for additional information if we are able to do the amicus brief. ALDF usually responds with a decision within fourteen days of receiving a request.


If you have questions about the process of requesting or filing an amicus brief, please contact ALDF’s Pro Bono Program at
