Thanks jain but in my case it is to late. I have already done the deal and been burnt. Now its a case of damage limitation. So its common practice for a develper to put down a lower price in front of the notary so he pays less taxes. The notary deeds cannot be changed, yet the contract told me to pay a lot more money than he put down on the notary deeds. i have paid him a lot more than what he has put down, so i am going to be clobbered with loads of capital gains tax i never gained. WHAT CAN I DO ABOUT THIS, IS IT WORTH TAKING HIM TO COURT.
