In Accordance With vs. In Compliance With

Both phrases can describe conformity with a rule or standard, but “in compliance with” more strongly foregrounds obedience to a requirement, while “in accordance with” is broader and can also refer to wishes, guidance, or agreed terms. The distinction is contextual rather than absolute; legal and organizational documents may define their own preferred wording.
