Posted by Laurent | December 03, 2025 | Hired Attorney | Lawsuits & Disputes
Paid $3,500. Received no work product. Retainer not refunded.
I hired Marc Hankin in August 2025 for a very specific task: to review and revise a settlement draft in an active federal litigation matter. I paid a $3,500 advance deposit with the understanding — written in email — that this would cover approximately one hour of review and any additional work relat...
Dear Laurent, Your "Review" is incomplete and, well, erroneous. Because you have clearly waived the attorney/client privilege as to the billings on your matter, the truth is that, although initially you had hired me with an Advance Deposit of $3500, you called and emailed me repeatedly and insistently, changing your desired strategy multiple times. I ended up billing you $4,213.50 for the time that you took, and the work that I did trying to resolve your situation, but when I shared that with you on September 4, 2025, I made it clear that I would be writing off the $713.50 that was above the Advance Deposit of $3500 you had paid. I did not hear back from you again for three months until December 3, 2025, when you demanded that I refund to you "the unearned portion of the $3,500 deposit" or else you would report me to the State Bar. I explained to you, once again, that I had performed MORE work than you had paid for, and that there was NO "unearned portion" to return to you. I also explained to you that I was not going to be bullied into returning to you money that I had earned just because you ended up hiring a different attorney who ended up charging you less than the $17,000 I had quoted you for the litigation that you were interested in fighting. There were NO "months of follow-ups requesting the return of the unearned portion" as I did not hear from you for three months after I wrote off your excess work. Perhaps you should revisit your so-called "review" above and correct the facts based upon the email history between us? That would give the public a more accurate view of what really happened here. Thank you, Marc

Unresponsive
Marc was very unresponsive. It was hard to get in touch with him and in the end I feel just took my case to make a few extra bucks because in the end, he really had no clue what he should do to help me. I ended up solving the problem on my own and when I went to be refunded my $1500, he told me he ha...
