TDS Deduction incase of Jointly purchasing property woth mither

Purchased a flat of 86 lacs rupees. I have given my mother name as joint owner in it. My mother is a housewife.

I have paid 20 lacs from my account to seller and for rest 66 lacs took a bank loan....in loan paper mother has signed as well as her name is there in property registry paper as joint owner.

I will pay all the EMIs as Mother is housewife.

So, who should deduct tds on 86 lacs Rs.....should I only deduct tds of 86k Rs. using my PAN as I have done all the payments....or should tds be deducted using my PAN as well as mother PAN I.e. 43k and 43k each.

Please suggest.
