The Orlando Sentinel reports that Sybrina Fulton and Tracy Martin's attorney, Benjamin Crump, filed that paperwork in Seminole County. Crump told The Associated Press that the filing was confidential.
The newspaper reports that the settlement amount was marked out in five pages made available for public review. In the agreement, the parties specify that they will keep the amount confidential.
Martin was fatally shot by then-neighborhood watch volunteer George Zimmerman during a confrontation in a Sanford subdivision a year ago. Zimmerman is pleading not guilty to second-degree murder, claiming self-defense. His trial is set for June.
A month-and-a-half delay in Zimmerman's arrest led to nationwide protests.
