Is it a rural agricultural land that he is offering you?
If yes no TDS is required to be deducted.
Else technically speaking as per section 194IA TDS needs to be deducted at the time of credit or payment whichever is earlier and hence payment was made in 2010 when no such section exist hence no need to deduct TDS on such 25 lakh just deduct on balance 30 lakh and show consideration as full 55 lakh as same would be reflected in the sale deed.
No TDS would be deducted on you selling your right as TDS needs to be deducted only on consideration for immovable property.
Hope you find the information helpful if you do please rate it 5 and provide your valuable feedback for my improvement.
Thank you.
