<prompt> Human: I resigned from this private investigation firm almost two months ago to continue working as an associate investigator at another firm. I spent several days last year investigating and gathering evidence on a guy who was clearly faking an injury and fraudulently claiming benefits. Ive now been asked to give a deposition and testify, as the case has gone to trial. Some of the other investigators who conducted surveillance on the claimant will also be there. Am I required to attend, and if so, how much can I bill my former employer? Is it the hourly wage that I currently make, or the hourly wage I made when I worked with them? Consulting fees? Expert witness fees? Thanks.  <response>: This seems like more of a rlegaladvice question, honestly. I dont know for sure, but I imagine if you havent been compelled by the court to give a deposition and testify, youre free to request whatever compensation you want. If youve been compelled to testify I dont know what - if anything - you can request for compensation.
