Why not ask the agency you are already talking to to help, assuming they are appropriatly equipped-as a radar controller it is unbelievably easy to find someone who is lost, and assuming you arent a million miles away takes about 5 seconds if you have a transponder, maybe 20 secs if you dont. paperwork will not be filled in if you ask for help, no one is going to ring the CAA and tell them you had to ask for help; and as already stated above it`s not illegal to get lost-busting CAS though is illegal - so ask for help early if at all unsure.
(apologies for spelling,it is early!)
