Nationwide Gifted deposit/ proof of funds

Vasquez65

Daughter has had offer accepted, DiP given,  ready to progress to full application.
She has £10k in a Lisa,  we are gifting £17k to make a 10% deposit,   I know we have to fill in the Nationwide form,   she will have it by Monday.   Will Nationwide ask for any kind of proof of our funds at this point?
I only ask because I am taking the £17k from my Sipp and it takes 2/3 weeks to sort out apparently as I’m crystalising the pension to access a tax free lump sum and there is a ‘cooling’ off period built into the process. 

So at the moment the only proof I can provide is a screenshot of my Sipp account with £17k of it already in cash in there.  I can also photocopy the forms when I receive them,  which should be next week. 

Will it delay them making a formal offer until the cash hits our bank account, which will obviously be mid Feb?
