While law firms in lower Manhattan opened their doors Monday for the first time in a week, Hurricane Sandy’s effects on other firms, like Sullivan & Cromwell and Fried, Frank, Harris, Shriver & Jacobson, have forced lawyers and staff to keep the pace remotely and from alternate locations in Midtown.

Sullivan & Cromwell’s offices at 125 Broad St. on New York Harbor remain closed but chairman Joseph Shenker said the firm hopes to be fully operational within one or two weeks. In the meantime, lawyers and staff are working from Sullivan’s Midtown office at 535 Madison Ave., where the firm maintains one floor and has temporarily leased three additional floors, Shenker said Monday.
