It’s a little more nuanced than that. Lawyers have ethical obligations to provide sound legal advice and counseling, whether they’re paid for it or not. As in, the legal ethics structure doesn’t really allow for (purposely and knowingly) doing a shoddy job. The lawyer could be on the hook for either doing a bunch of free work or getting disbarred by signing up to do a ‘bare minimum’ job. Maybe there should be a carve out for situations like this.
