This is a legitimate and reasonable process that occurs frequently in mainland US as well. Especially if you purchase land at auction. Part of the process involves publishing efforts to ensure that all potentially affected parties are made aware of the action. Creditors are hesitant to deal with any questionable land until title has been quieted by this process so they know the purchaser has full ownership and there can be no further disputes. The quiet title process is a request for all those with interest in the land to speak up and resolve the situation. This prevents, for example, handing out a construction mortgage for someone to build a home on the land and then realizing three years later that your collateral is in jeopardy because several entities have decided to dispute the mortgagee's right to that land after the home was built.
