Is the custom validation to do with data in the invoice? I believe you can access the invoice that the details belong to in the validation. Also possibly reject_if on accepts_nested_attributes_for might do the job. If all else fails you could add a non-database attribute to invoice details and set that prior to saving, then pick it up in the validation.
