Simple codicil

The following language would be sufficient for a specific bequest:

"I hereby give and bequeath the sum of $XXXXXX to The Rotary Foundation (Canada) Charitable Organization Number 11912 5797 RR0001, to be used as the directors of the Foundation may from time to time determine."

And for a gift of the residue of the Estate could state:

"I hereby give and bequeath the residue of my Estate to The Rotary Foundation (Canada), Charitable Organization Number 11912 5797 RR0001, to be used as the directors of the Foundation may from time to time determine."
