Assigning a car without the logbook, Possible?

[Trevatanus]

So, Mr and Mrs Trevatanus are no more, and she has moved away.
Car is in my name and I want to assign it to her, as currently I am paying the road tax.
She is being a little slow in posting the log back back to me though ( I cannot imagine why!) , and I really want to assign it to her asap.
Do I need her to play ball?

OP why has she got the V5C if you are the RK?

Was in a pile of papers that she took when she moved it. Basically misfiled.
