Estate planning for your Mechanics 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.

Across 14 product types, Mechanics Bank accounts vary in how they transfer at death. The sections below walk through Payable on Death (POD) designations, trust funding options, and which products support each method.

1
Visit any Mechanics Bank branch (branch finder at https://www.mechanicsbank.com/locations/). Mechanics Bank publishes no downloadable beneficiary form -- the designation is made on the bank's own account documentation, which is why this is a branch or phone task rather than a download
2
Tell the banker which structure you want. The Personal Account Agreement recognizes several, and they behave differently at death:
  • Payable on Death (P.O.D.): you keep full control during life; on the death of the last surviving owner the funds pass to the surviving designated beneficiaries
  • Totten trust ("in trust for" / ITF): an informal trust account with no written trust agreement; a beneficiary must survive the death of ALL account owners to take anything
  • Joint with right of survivorship: the deceased owner's share passes automatically to the surviving owner(s)
  • Tenancy in common: the deceased owner's share passes to their ESTATE, not to the co-owner, and goes through probate
3
Give the banker each beneficiary's details:
  • Full legal name
  • Date of birth
  • Social Security number
  • Relationship to the account holder
  • Percentage allocation, in writing, if you do NOT want equal shares -- the agreement pays multiple beneficiaries equally unless the bank has been instructed otherwise in writing by the owner
  • A current address for each beneficiary; the agreement asks owners to keep the bank informed of each designated beneficiary's address
4
Sign the account documentation with the banker and take away written confirmation that the designation is on the account

Required Documents

  • Trust name, date established, and tax ID (EIN or SSN)

Special Requirements

  • Mechanics Bank does not publish a public beneficiary designation PDF; designations are made on the bank's account documentation in-branch or by phone
  • Multiple P.O.D. beneficiaries receive EQUAL shares unless the owner instructs the bank otherwise in writing
  • On a Totten trust ("in trust for") account, a beneficiary must survive the death of all account owners to receive anything
  • A tenancy-in-common account does NOT pass to the surviving co-owner: that share goes to the deceased owner's estate and through probate
  • California, Washington, and Hawaii are community property states, so spousal consent can be required for an IRA beneficiary naming someone other than the spouse
