I'm following up on the above. Without some further information from you as above, I am limited in what I can say on the matter but in the hope it is helpful nonetheless, I will provide you with the following broad answer. If you are able to kindly provide me with the above further information or if you have any further questions generally, I will be delighted to expand on the following - please just reply back to me in this case:
Notwithstanding the above, in general terms much will depend upon the quality of evidence you have to show that you paid for the land in question. From what you say, you have a receipt for the money you paid but I am not clear on how specific the terms of that receipt is. providing the receipt adequately describes the extent of land you have bought, ideally in sufficient detail to conclusively identify it, then the fact that you have a receipt for purchase in respect of that land will operate as a conclusive contract purchase. If by contrast, the receipt is vague or worse, does not identify the land you have bought at all, then you have a receipt but it would be open to the seller to claim that the receipt was for something different, for example a smaller amount of land or indeed something entirely different depending upon how detailed the receipt is.
If you have a clear receipt which is unequivocal in terms of identifying what you have bought, then you can enforce that as a contract either by specific performance in court or by negotiation with the seller
I hope the above is of some assistance but if you have any further questions, please revert to me
