I would pass it on to a collegue. I work for local authority and wouldn't be comfortable looking into private details etc of friend/relative. I know when it's come up for others they have explained and passed it on.
Also I wouldn't do it as it could lead to problems for you - anything irregular (and in situations where the answer isn't in black and white it's likely) then what would happen if there was comeback on you? It looks a bit dodgy to be doing stuff at that level for a friend or relative.
Also if you don't make a decision they like or don't agree with doing what they want to do what will happen to the friendship then? Especially if it is an emotive issue.
I wouldn't touch it with a bargepole tbh.
