Use the models Meta class unique_together. You can find the excellent documentation here.

class newlist(models.Model):
    class Meta:
        unique_together=('user','list_name')
    user = models.ForeignKey(User)
    list_name = models.CharField(max_length = 100)
    picture = models.ImageField(upload_to='profiles/', default = "/media/profiles/default.jpg")
    slug = AutoSlugField(populate_from='list_name', default = '')

    def __str__(self):
        return self.list_name
    def save(self,*args,**kwargs):
        try:
            return super(newlist,self).save(*args,**kwargs)
        except IntegrityError: # This is raised if the object can't be saved.
            # Your error handling code
            from django.core.exceptions import PermissionDenied
            raise PermissionDenied()
