A Casa é Minha (2013)

Two families, deceived by a cunning real estate agent, purchase the same house and end up moving in on the same day, unaware of each other's existence. The matter goes to court, but due to the slow judicial system, it may take years to be resolved. The only way for one family to gain ownership of the house is if the other cancels the purchase, but neither family is willing to give up on the house, resulting in a situation where they have to live together until the case is settled.
