I've found the form I think you need. I tried to get you a direct link but that didn't work so here's what you need to do:
Copy & paste the above link to go to the Friends Life documents library.
Scroll down to the tab marked "general" - which is second from the bottom of the list.
Click on the + sign.
A long list of documents will then unfold.
About a third of the way down the list, you will see a document called:
Deed of Assignment to Change the Legal Ownership of a Life Assurance Policy.
Click on it, and a PDF document will open, which you can print off.
The number for queries is 0845(###) ###-####/span>, so you can check with Friends' Life that this is the correct form. Yoou will also need to check whether it's the name of the executor that is now the assignor, or whether that remains the name of decceased. If the policy is in joint names of the deceased woman and her husband, then I think that her husband will probably also have to sign the form to assign the benefit of the deceased woman to her daughter.
I would strongly advise you to get advice from a probate solicitor before completing the form.
I hope this helps and I wish you the best of luck.
Thanks and best wishes...
