I have a friend who has had a 20k fine, and an embargo put on his house.
He has had illegal works done on his house, acting on the advice of a solicitor, who said that it would be OK, and charged him 11k.

He wonders what will happen next. He believes that the house will be put to auction, to raise the 20k, and expects that only "certain people" will be invited to the auction, so that it will just get 20k, plus fees.

Obviously, this means that he will lose his life savings.

His house is worth about 300k, with no mortgage. He is above retirement age, and heading for a heart attack.

Does anyone know what normally happens after such an embargo? Or can anyone advise?

We are in Malaga province, Guadalhorce valley
