JAMS, a leading provider of alternative arbitration and mediation services, is moving to two full floors at 3 Times Square. The lease for over 55,000 square feet brings the Rudin-owned tower to 75% full.

The tenant is expected to move from 620 Eighth Ave. in the fourth quarter of 2027.

JAMS president/CEO Kimberly Taylor said her firm “has a longstanding presence in New York, and this relocation represents an important investment in our future here.”

Rudin and its joint-venture partner Thomson Reuters recently completed a sweeping capital improvement program at the tower.

Meanwhile, SL Green completed two leases at 711 Third Ave. between East 44th and 45th streets.

Fidelity National Title Insurance Company signed a new lease for just under 20,000 square feet while Ackman Ziff Real Estate Group renewed on 14,598 square feet.

A recent major renovation of the midcentury tower designed by William Lescaze & Associates includes a gallery-style lobby showcasing an original Hans Hofmann mosaic mural. CBRE’s Joseph Fabrizi repped Fidelity National and Ackman Ziff was repped in-house.
