Paternity and handing in notice

[mattdsc]

We have our first due in early December and I am looking to change jobs. I understand my notice period (which is 3 months - not ideal - any advice on reducing that would also be appreciated!)

I have filled in the appropriate paternity leave forms well in advance, so thats all in and formal, but if I hand my notice in the next week or so, can the business take away my paternity leave? Is there any law
