Mid Atlantic Trust is now part of AscensusAcquired
Mid Atlantic Trust Company does business as American Trust Custody, and American Trust Custody is now part of Ascensus: every page of americancustody.com carries the banner "Ascensus has completed its acquisition of American Trust Custody." The legal entity is unchanged — the South Dakota Division of Banking still lists Mid Atlantic Trust Company as a chartered public trust company (TC.056-2) on its September 2026 roster, and the phone numbers, email addresses, and Pittsburgh address below are the ones the company publishes today. Statements, checks, and 1099-R forms may carry either the Mid Atlantic Trust or the American Trust Custody name. The company website is americancustody.com; midatlantictrust.com no longer resolves and macg.com redirects there.
Estate planning for Mid Atlantic Trust retirement retirement accounts revolves around beneficiary designations. These designations—not a will—control who receives the account balance at death.

The transfer rules at Mid Atlantic Trust vary across 11 retirement accounts. Below is a breakdown of beneficiary options, trust funding, and which products support each method.
