TMZ obtained a copy of Royce Reed's motion -- filed in Orange County, Florida yesterday -- in which she claims the Orlando Magic star regularly misses scheduled visitations with their son Reed. Royce also alleges that their son "acts out emotionally and physically and resists being taken by" Dwight's nanny ... according to the docs.
As TMZ first reported, cops were called in two weeks ago when Royce claimed that Dwight picked up little Reed from preschool when he wasn't supposed to do so.
Royce is asking the court to appoint a guardian -- on Dwight's dime -- to ensure Dwight follows the visitation schedule and Reed gets proper care. Royce's rep says the motion was filed, "as a last resort."
Dwight's reps have not returned our calls.
