The only liability issue I can think of for the adoptees would be during a work party if someone on the work detail got hurt, and the agency usually has some pretty bullet proof boilerplate either in the agreement or the event waiver. A non-member getting hurt during a work party would be lack of common sense by the workers, and if someone from the public is hurt just using the area, oh well, too bad in most cases. The agency would be the designer and overseer of any improvements the adoptee's would do.
