A Sydney lawyer who claimed her ex-husband and a former client were behind the wheel of cars caught speeding or running a red light when her son and father were to blame has been found guilty of professional misconduct and struck off the roll of solicitors.

Jinhi Kim, who was employed by several law firms in Sydney, pleaded guilty in the Local Court in August 2016 to using the details of her ex and a client without their permission to change the driver named in the penalty notices.

As part of a plea deal with the Director of Public Prosecutions Ms Kim also admitted she committed four similar offences, which was taken into account during sentencing.

She was fined $2200 last year and entered into a two-year good behaviour bond.
