Tds on property (2 sellers)

Need Clarification on following :-

I have purchase a Flat and Flat was in the joint name of Sellers (Owner :- Husband /Co-Owner :- Wife).. I have paid my contribution to Owner only and rest amount financed thru Bank and Bank has isused two equal cheques to Owner and Co-owner. But while deducting TDS I have deducted full TDS in the name of Owner only and issued Form 16B in the name of Owner.

Both Seller is filling Seperate IT returns and showing seperate income from capital gain (althought They have invested in other property so Tax liabilty will be Zero and TDS willl  refunded)

My quesry is whether TDS deducation was correct and there is no defalut from buyer side,?

Is there any legal problem can arise to Seller ?
