In the movie, Gone Girl, Nick hires a lawyer from New York, Tanner, whose legal retainer is 100k.
I searched a bit on the internet, a legal retainer is an upfront fee that you pay for in order to ensure a lawyer's commitment. It does not represent the total cost of a legal case.
- In short, it is the minimum fee to have a lawyer see a case through.
But Nick has never been charged in this movie, hence no legal case. I am wondering if Nick is required to pay off Tanner.
- My assumption is he does indeed pay tanner off, as Tanner walks away from Nick on good terms.
