Sunil is a licensed paralegal who specializes in representing clients charged with summary conviction Criminal Code offences. One of Sunil’s clients named Barney retained Sunil to represent him to defend a public nudity charge from when he went skinny dipping at a public beach in the summertime. Barney’s trial is scheduled to commence in four months but he has not paid any of his interim statements of account on the matter. Sunil is reluctant to continue with the file because based on his interactions with his client, he does not think that Barney will pay the fees they agreed to in their paralegal-client retainer agreement. For Sunil to withdraw from representing Barney for non-payment of fees, what requirements must he satisfy to meet his professional obligations as a paralegal?
