    Sobel joins from Paul, Weiss, Rifkind, Wharton & Garrison LLP, where she worked in the firm’s antitrust and M&A groups and led teams handling Hart-Scott-Rodino Act matters, according to a statement issued by Weil on Monday.

    The appointment strengthens Weil’s ability to advise companies and investment firms on regulatory approvals, transaction risks and merger-control requirements in the United States and internationally.

    Sobel’s practice focuses on antitrust issues arising from private equity investments, public-company acquisitions and corporate restructurings. Her experience includes developing strategies for obtaining regulatory clearance, assessing competition-related risks and negotiating transaction provisions intended to address potential regulatory obstacles, Weil said.

    The Hart-Scott-Rodino Act requires parties to certain qualifying mergers and acquisitions to notify federal antitrust authorities before completing their transactions, allowing regulators to review potential competition concerns.

    Weil’s leadership described Sobel’s recruitment as part of a broader effort to expand the firm’s transactional and regulatory capabilities.

    Barry Wolf, identified as Weil’s executive partner in the announcement, said Sobel’s merger-control experience would strengthen the firm’s ability to serve clients across its international operations.

    David Lender, co-chair of Weil’s global litigation department, emphasized the importance of Sobel’s HSR expertise for clients undertaking complex acquisitions and private equity transactions, according to the firm’s statement.

    The appointment comes alongside a series of senior-level additions and leadership changes at Weil.

    The firm cited the appointments of Kyle Krpata and Michael Lubowitz as co-chairs of its corporate department, as well as the returns of private equity partner Peter Feist, banking and finance partner Damian Ridealgh and restructuring partner Debra Sinclair in New York.

    Weil has also expanded its private equity teams through partner appointments in San Francisco, London and Frankfurt, while adding capital markets partner Shu Du in Hong Kong, according to the announcement.

    Sobel brings professional experience extending beyond her law firm practice. She serves on the executive committee of the New York State Bar Association’s Antitrust Section and previously chaired its Mergers Committee.

    Michael Moiseyev and Brianne Kucerik, co-heads of Weil’s U.S. antitrust practice, said they had worked opposite Sobel on matters over several years and were familiar with her approach to complex competition and merger-review issues.

    In comments included in Weil’s announcement, Sobel said she intended to help clients address increasingly complicated regulatory requirements while providing commercially focused advice aimed at improving transaction certainty.

    The hiring adds to Weil’s antitrust bench as the firm seeks to integrate competition-law advice more closely with its corporate dealmaking and private equity services.

    Founded in 1931, Weil operates offices across the Americas, Europe and Asia and employs approximately 1,200 lawyers, according to the firm’s published information.
