ISBA Ethics Opinions on Communication With Adverse Person

Opinion 01-06 | Communication With Adverse Person | Frivolous Arguments
Harassment of opposing party and third-persons

While a lawyer may zealously represent the interests of a client, a lawyer must be truthful in dealings with adversaries and third parties and cannot take actions designed merely to harass or burden such other parties.
Opinion 96-03 | Communication With Adverse Person | Deceased or Missing Clients
Disclosure of client’s death

Opinion 91-21 | Communication With Adverse Person | Communication With Represented Person
Lawyer communication with adverse party’s in-house counsel without knowledge of adverse party’s retained private counsel
Opinion 85-05 | Communication With Adverse Person | Communication With Represented Person
Notice required by agreement directly to opposing person
