A breach of contract lawsuit that is playing out in California state court raises issues about billing practices and disclosures in Big Law, as Baker McKenzie stands accused of breaching retainer agreement by not notifying its client when fees and costs reached a certain threshold.

California-based workplace services company SBM Management Services alleges that the global giant violated a provision in a retainer agreement that required SBM to be alerted when the firm neared "specific spending milestones," in a suit that was refiled Monday in San Francisco County Superior Court after being initiated in Sacramento in February.
