M&T Bank has 12 accounts, each with different rules for what happens when the account holder dies. Of those, 10 can name a trust as beneficiary or be retitled into a trust. The right combination of beneficiary designations and trust ownership can keep the entire portfolio out of probate.
Beneficiary designations at M&T Bank can be managed in branch and by phone, typically taking 15-30 minutes in branch. Trust funding is also available, allowing families to retitle accounts into the name of a revocable living trust.
M&T Bank provides specific procedures for both proactive estate planning and filing claims after a death.

Frequently asked questions
No — they are different services at different prices. Retitling an M&T deposit account into your own revocable living trust is branch paperwork: bring the trust agreement or a Certificate of Trust, ID for all trustees, and the trust EIN if it has one. You remain trustee and run the account. Engaging Wilmington Trust, M&T's Delaware-based wealth affiliate and one of the largest corporate trustees in the United States, as corporate trustee or co-trustee is a fiduciary engagement with its own asset minimum and ongoing trustee fees — confirm the current threshold and fee schedule at 1-800-982-4620. The substantive reason people use Wilmington Trust is situs: it administers trusts under DELAWARE law regardless of where you live, and Delaware permits directed trusts that split the investment role from the distribution role, long-term dynasty trusts, and asset protection trusts, with favorable trust income tax treatment. That is a real estate-planning decision, not a banking one. Consult a licensed attorney about whether Delaware situs fits your plan.
