Mike Pero may have to pay back more than 1.5 million dollars to his own business, after giving himself a pay rise.

Mike Pero is CEO of Mike Pero Real Estate - half-owned by his company Mike Pero Marketing, and by Mike Pero Mortgages which he's no longer a part of.

The mortgages and marketing businesses agreed in 2011 that Mr Pero would be paid 200-thousand-dollars a year for his CEO role.

But a High Court judge says Mr Pero dramatically increased his own remuneration package, gave himself a car allowance and a 125-thousand-dollar a year brand ambassador payment.

A judge has ordered Mr Pero and his marketing business to pay his real estate business anything received by them over 200-thousand-dollars a year ... with interest.

Mr Pero told our newsroom he was only seeking fair market value for what he was doing.

He said the $200,000 salary is less than his top 10 agents earn in annual commission.

Mr Pero says he took legal advice when changing his remuneration and had his position independently valued.
