Surely you jest. We wouldn't have a clue as to how long the trustee will sit on your money.
No one here can tell you because no one knows the specifics of the trust fund. Trusts can vary widely in their construction. Ask the trustee.
you may have to request the money, beware. contact the trustee/custodian in writing NOW and tell them your bank account to wire the money to!
The custodian of the trust has that answer. Only guesses here.
