You can do it in your modal class's specific property using the ErrorMessage property in the of Required attribute.

Ex:

public class MyClass{

    [Required(ErrorMessage = "My validation error message goes here")] //give your validation message here
    [Display(Name = "My display name")] //Give your display name here
    public int NumDoc{ get; set; }
}
