I refer to the IFLR1000 especially with respect to jurisdictions I have no knowledge about. The main reasons: to find a good firm or confirm standing of a firm recommended by someone else.
I usually use the IFLR1000 in connection with a need to engage a local counsel on an M&A deal.

We refer to the IFLR1000 because of the breadth of jurisdictions it covers, the succinct clear layout and leading lawyer recommendations.
We use the guide in particular where we are taking security in unknown or little-known jurisdictions.
