Who would you rather have review litigation documents: contract (temp) lawyers or full-time lawyers in India?
In Document Review in the US versus India (8/07) I suggested that Indian lawyers likely do better reviewing documents than US contract lawyers.
For a well-written, colorful, amusing, and depressing article about the life of temp lawyers doing doc review, read Attorney at Blah (Washington City Paper, 11/7/07). Those skeptical of offshore review should read this for good anecdotal insight into the typical domestic alternative.
I found this article referenced at The Secret Life of Contract Lawyers at Legal Blog Watch, where Carolyn Elefant comments on the article and provides links to other resources re document review and contract lawyers.
