The Richmond Legal Development Center opened this summer as the state’s first incubator for new attorneys. Participants learn how to run their own practices, receiving advice from established lawyers and getting tips on tax planning, billing practices and holding money in escrow accounts. Each attorney pays $350 a month in rent to start, which covers a furnished office, utilities and the use of several common areas on the second floor of Picard Rowe & Rosen at 8310 Midlothian Turnpike. Barbara Picard and her legal partner own the building Picard Rowe & Rosen calls home. After reorganizing, the firm no longer needed the second floor, and Picard saw an opportunity to start the incubator. The program is one of only 13 or 14 legal incubators in the country. The center’s attorneys work like any other lawyers would: They meet with clients, write legal documents and go to court. But they can also call on a group of more than 20 local attorneys who answer questions, give guidance or collaborate on cases, and they attend weekly training seminars that often focus on the business side of owning a law practice.
