Car insurance when transferring ownership

goodread

We want to transfer ownership of my Mum's car to a family member. This will mean Mum cancelling her car insurance and a new policy for the family member. 

Is it best to overlap the policies (both to cancel and start on the 15th), or cancel on the 14th and start the new one on the 15th?

How is this "ownership" being transferred?

Unless ownership is going to transfer at midnight in most cases there will be an 1 day or part of 1 day overlap

Does the other family member currently have a policy on a different vehicle?

If the family member lives near you Mum could she deliver it on the agreement that the car stays off the road until the following day?  She could then cancel her insurance and the new owner insure from the following day.

Thank you all for your input.  Basically I thought if my sister (the family member involved) went round to Mum's and she notified the DVLA online of the change to the logbook, and then set up the tax, while she was there. Ideally she'd drive the car away at that point but it's the insurance I wasn't sure about.
