Probate OR?

Grandfather died with trust.
Also had stock accounts for grandchildren with him as custodian and the kids names.
The trust is straight forward but because he is personally the custodian (not the trust) my understanding is the trust has no interest in these accounts.
Will we have to go to probate?
If so - how complicated might it be. Other 'heirs' involved?
Thanks

Not enough information by a longshot.

Was he married at the time of his death?
How many adult children did he have?
How many grandchildren?
Their ages of the grandchildren?
How much money in the accounts?
Did he leave a will in addition to the trust?
If he left a will did he nominate someone as executor or representative of the estate?
If yes, who?
If he left a will, was it a "pour over" will?
Who is trustee of the trust?
What assets are owned by the trust?
How much is the trust worth?

So, yeah, it's likely to be complicated.
In the interest of privacy you probably shouldn't answer those questions on the internet.
I posted them to illustrate some of the information that a lawyer will probably want.
