Hi
1) It appears that your problem is a problem pertaining to boundaries
2) The factual position at ground is that the boundaries of the site are as follows: Your site survey number is 269 bounded by neighbouring site 267and site number 270
3) whereas the document states that your site number is 269 bounded by site survey number 268 and survey number 270
4) If you wish to proceed with the sale you should do the following
a) Get a FMB Sketch for the property you intend to purchase by Revenue officials.
b) A rectification deed by the seller
c) Panchnama of boundaries by neighbouring land owners
c) Paper advertisement asking for objections for proceeding with the sale.
5) If you wish to cancel the sale agreement and since you have the original documents from the seller you should do the following
a) Issue notices to the seller intimating him on the grounds(incorrect boundaries) in his agreement of sale and
b) Hence cancellation of agreement of sale and
c) Ask for refund of monies in full within 30-45 days and
d) Upon receipt of money handover the original documents back to seller.
6) You can also file a caveat in court in case you are apprehensive that seller might approach the court and
7) If you think that the Seller in order to frustrate you might alienate/sell the property to other persons, obtain a interim injunction against the seller from alienating/selling the properties till such time your monies are returned along with interest.
Hope this information is useful
