How does an owner of a car get the logbook back off an unwilling registered keeper?

[kelmayo77]

My friend is going through a break up and His Ex will not hand over the logbook (which is in her name) of a car they purchased 4 months ago, My friend is paying finance on this car yet she refuses to hand it over she has told him that she has taken his name off the insurance so even though he has a key to take it he can not get the insurance to drive without the logbook. In my opinion this should be classed as theft as he is the legal owner and she is now driving it and withholding the logbook without his permission Any advice would be greatly appreciated.
