The Dewey & LeBoeuf estate hopes to void two dozen leases on office space the now-bankrupt firm occupied around the world before it ceased practicing law last month, according to a filing made Wednesday in Manhattan bankruptcy court.

Bankruptcy law allows for the so-called lease rejections, which require court approval and are likely to encounter opposition from some of the firm’s landlords. (In a case involving another defunct law firm, Howrey, landlords are still fighting with the estate more than a year after the firm went bankrupt.)
