It’s long after business hours — do you know where David A. Hirsch is? The Burlington, Iowa, litigator is in his home office, maintaining Beckman & Hirsch’s law firm Web site, at www.iowalaw.com. He says that he strongly prefers to work on the site from home, at night, as there are few interruptions. “We’ve got Web maintenance down to the point where we can do it from anywhere,” he says. “I could do it from my Palm Pilot, but I don’t.”

As the ability to plug in to a law office network (or Web site) improves, so have home offices, mostly because they let lawyers enjoy dinner and weekends with the family, but also because of the efficiency that comes from avoiding office interruptions. Mr. Hirsch also receives some clients, such as doctors, at his home office because their regular business hours are booked.
