The $1.6 million legal malpractice claim against Duane Morris revolves in large part around whether a settlement agreement the firm helped its client reach should have provided security in the event the other side did not pay up, according to attorneys in the case.

In opening statements on Tuesday in Adlerstein v. Duane Morris, physicist Joseph K. Adlerstein’s attorney, Clifford E. Haines, said Duane Morris was responsible for his client only receiving $200,000 of a $1.8 million settlement with SpectruMedix, the company he founded. And that $200,000, he said, ultimately went toward rising legal bills from Duane Morris. Haines is the name partner with Clifford E. Haines & Associates.
