In the case you have entered into purchase contract with Mr. S.
( Car of 1 million yen )
Though, you have paid purchase price to Mr. S, he refuses to deliver the car to you.
Then, you will hire a lawyer to make law suit.
In this case, the amount of lawyer’s fee may be 300000 yen.
Then, fortunately you have won in civil suit.
But, in Japan you can not charge fee for lawyer ( 300000 yen ) against Mr.S.
You can receive only 1 million yen and you need to pay 300000 yen by yourself.
