Depending on the facts, it can be an extremely complicated process. For example, the bank may not be the only person who has a security on the property. Another person may have registered a judgment mortgage. Consequently, they would be entitled to some of the proceeds ahead of the individual. As a result, the sale needs to be advertised, other parties can get involved etc. That's why the Examiner's Office gets involved to make sure everything is done above board.
Here's another good article that explains the processs:
Many of the media reports about these types of court cases rarely scratch the surface of the real legal process behind them preferring to focus on the headline of the number of "sale/possession orders" granted.
In any event, please follow my earlier post and seek legal advice.
