I also have no experience with this, these are just my thoughts;
I don't see any problem with seeing the ENFE in another county. The report may not be filed in your county but it is just for helping to clarify your (and your stbx's) financial situation anyway. I do think someone with a financial background is probably more likely to understand certain financial implications related to property division than others. Things like time-value of retirement funds and current and future income and property tax ramifications due to property divisions and dispersements.
As long as you are not bound by the EFNE's recommendations then I don't see a problem with it.
Just my opinion ... and that's not worth much

Best of luck to you as you work through this
