If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms.

MMA’s source names professional E&O alongside architect/engineer and lawyers lines. A firm using contractors or facing professional-board proceedings should compare those listed features with the wording and insured-person definitions in the MMA form proposed for its profession.

MMA’s source identifies several professional product lines. Ask each team whether the proposal combines or separates professional, technology and cyber limits, then review how overlapping service and technology allegations are handled.
