Estate planning for your Stellar Bank accounts starts with understanding how each one transfers at death. Beneficiary designations and trust retitling both bypass probate, but the right approach depends on the account type, your tax situation, and how much control you want over distributions.
Stellar Bank offers 5 accounts, each with its own transfer rules. The sections below cover how to set up beneficiaries, fund a trust, and which products support each approach.
Required Documents
- Trust name, date established, and tax ID (EIN or SSN)
Special Requirements
- POD beneficiaries on deposit accounts pass directly to the named beneficiaries outside the will
