Litigation surrounding the dissolution of 12-attorney Arkin Kaplan Rice turned vitriolic this week, with accusations made in court papers that one partner left a threatening voicemail and another was involved in a “fists up physical altercation.”

Veteran litigator Stanley Arkin and his partner Lisa Solbakken brought suit this month on behalf of Arkin Kaplan Rice against Howard Kaplan and Michelle Rice and their new firm, Kaplan Rice. The Arkin firm, now in dissolution, claims Kaplan and Rice are occupying the dissolved firm’s office space without paying rent and have refused to report hours they billed at the former firm.
