If your situation is different
These Letters are delivered to you as an employee of an institution
When these Letters of Guardianship (Letters) are delivered to you as an employee or other representative of an institution or financial institution in order for the guardian of the estate (1) to take possession or control of an asset of the minor held by your institution, or (2) to open or change the name of an account or a safe-deposit box in your financial institution to reflect the guardianship, you must fill out Judicial Council form GC-050 (for an institution) or form GC-051 (for a financial institution).
An institution under California Probate Code section 2890(c) is an insurance company, insurance broker, insurance agent, investment company, investment bank, securities broker-dealer, investment advisor, financial planner, financial advisor, or any other person who takes, holds, or controls an asset subject to a conservatorship or guardianship other than a financial institution.
Institutions must file a Notice of Taking Possession or Control of an Asset of Minor or Conservatee (form GC-050) for an asset of the minor or conservatee held by the institution.
A single form may be filed for all affected assets held by the institution.
An officer authorized by your institution or financial institution must date and sign the form, and you must file the completed form with the court.
The guardian should deliver a blank copy of the appropriate form to you with these Letters, but it is your institution's or financial institution's responsibility to complete the correct form, have an authorized officer sign it, and file the completed form with the court.
There is no filing fee for filing the form.
You may either arrange for personal delivery of the form or mail it to the court for filing at the address given for the court on page 1 of these Letters.
If the correct form is not delivered with these Letters or is unavailable for any other reason, blank copies of the forms may be obtained from the court.
Financial institutions
A financial institution under California Probate Code section 2892(b) is a bank, trust (including a Totten trust account but excluding other trust arrangements described in Probate Code section 82(b)), savings and loan association, savings bank, industrial bank, or credit union.
Financial institutions must file a Notice of Opening or Changing a Guardianship or Conservatorship Account or Safe-Deposit Box (form GC-051) for an account or a safe-deposit box held by the financial institution.
A single form may be filed for all affected accounts or safe-deposit boxes held by the financial institution.
