A fraudulent quit claim deed was filed in Miami dade county Fl on a property I own with my 2 brothers, what do I do

Civilly, the proceeding is called an action to quiet title. You go into court and hash out all the reasons why the new deed should be invalidated. You probably want a real estate litigator on this.

A quitclaim deed, even though it may have been fraudulently executed, creates a cloud on the title to your property, assuming that the quick claim deed was properly executed with the proper formalities. In order to remove the cloud on title, you will need to file a quiet title action.

I am sorry to hear of your trouble. I'm sure it is especially aggravating since it involves family members. You need to immediately file an action to quiet title. Perhaps, the most important thing the action will do for you is allow for the filing of a paper in the public records called a Lis Pendens. A Lis Pendens gives notice to any prospective future buyer of your claimed rights in the property thus preventing them from taking title without notice of your rights, and thus preventing a further complication. Best wishes.

Call the property appraiser and clerk of the court, or go in person, and report the fraud. Miami Dade County is really cracking down on all real estate fraud and will take your complaint and investigate it.
