Danica L. Muir

DANICA MUIR has significant experience representing global financial institutions — including foreign banks, investment funds, and hedge funds — in complex commercial litigation. She advises clients in high-risk, highly regulated industries, particularly in financial services and investment management, and regularly appears in federal and state courts, arbitrations, and bankruptcy proceedings.

Danica’s practice includes multijurisdictional disputes and internal investigations, with litigation experience spanning all phases of the process — from pre-litigation strategy and risk assessment to pleadings, discovery, motion practice, trial, and settlement. She plays a key role in advising clients on high-stakes matters, including those involving parallel proceedings in the U.S. and abroad.

Prior to joining Sidley, Danica worked at another global law firm.

Danica earned her J.D. in 2017 from Howard University School of Law, where she served as the executive solicitations and submissions editor for the Howard Law Journal.

• A consortium, headed by APG Asset Management N.V. (APG), on behalf of the largest Dutch pension fund, ABP, and Australian Retirement Trust (ART), in the acquisition of Riverstone Holdings’ equity stake in Pattern Energy Group LP (pending).
• A global asset manager in a long-term partnership dispute with counterclaims for declaratory judgment, conversion, specific performance, and breach of contract.
• Commercial landlord in action against retail tenant for nonpayment of rent arising from the COVID-19 pandemic.
• An investment firm in action against the City of New York for declaratory judgment and specific performance to enforce its purchase option under a ground lease.

Some of the above matters were handled prior to joining Sidley.

Danica currently serves on the Junior Advisory Board for Her Justice. In 2023, Danica was presented with Her Justice’s 20th Annual John K. Geiger Award. The award is presented to attorneys “whose unyielding compassion and dedication toward their clients is truly outstanding.” Danica also is a member of SidleyWomen.

Danica maintains an active pro bono practice representing clients who have legal needs in the areas of matrimonial and family law. 

During her years of service volunteering with Her Justice, a non-profit organization that provides free legal help to women living in poverty in New York City, Danica has represented numerous clients in their matrimonial and family matters, including two trials during the pandemic resulting in favorable child support and visitation terms.

Danica was also part of a Sidley pro bono team to help ensure that Preston High School, an all-girls, private, Catholic, college preparatory school in the Bronx, would remain open. The school, which was founded in 1947 by the Sisters of the Divine Compassion, is known for its broad curriculum and emphasis on Christian service. Following a public hearing on April 22 by the Office of the New York State Attorney General, Sidley facilitated the purchase of the school from the Sisters of the Divine Compassion by Bally’s Foundation of North America, a charitable non-profit organization, which will lease the property back to the school on highly favorable terms, with options to renew the lease upon the completion of the original term.
