I have been employed by my place since February this year, and have handed in my notice, 3 months, and starting a new place in January.
I recently found my P45 from the job before current one in a pile of paperwork 
Question: do I need to send it to my current employer so it can 'go through' them before it then gets regenerated for the new place? Or can I not bother?
Clueless, hoping a wise MNer can help
