Shaw and Lederer were ordered last month to turn over the instruments to a trustee to help pay a $611,000 judgment to former Audubon violinist David Ehrlich. According to the Times-Dispatch, however, the deadline was extended because progress has been made in negotiations between the musicians.
Violinist Akemi Takayama is negotiating with Ehrlich separately, the paper says.
Ehrlich sued his fellow musicians in 2000 after they ejected him from the group. A Pennsylvania court eventually ruled in his favor and awarded him a share of the estimated worth of the quartet.
Shaw and Lederer, who are married, have declared bankruptcy and given up all of their assets, including their home. They have sought to retain their instruments or come to an agreement that allows them to continue to use them pending appeals in the Pennsylvania case.
