I believe they use outside law firms.
- They use outside consultants.(Remember ARC?)
- They will use outside contractors. (Fancy new HQ buildings/sites)
- They are outsourcing the printing of the publications now in some country(ies?)
- There cannot be enough JW lawyers to keep up with all the lawsuits that the WT faces, especially nowadays.These are specialized and critically important. They can't have half assed screw ups. While I am sure that they have a few very competent experienced lawyers, with thousands of congregations, KH's, conferences all the time and 8 million minimally educated JWs, there can't be enough lawyers numerically to deal with it all.
