Proof of Funds from multiple account after ITA

I have a query regarding the funds
My scenario is :
I have an amount X in YESBANK which is on my name for 6 months.I am the primary applicant. I opened the joined account with my spouse in SBI and I transferred the same amount from YESBANK TO SBIBANK. So my amount is in YESBANK for 6 months and in SBI for like 3 months now.
The remain amount will be transferred to SBI as a gift deed.
My question is will this be accepted
1)if I get a letter from both the banks telling the amount and number of months it was in the respective account
2)is it compulsory that the amount should be in joint account for 6 months.!?

Thanks
