I am a broker, who facilitates (finds for his customers/buyers) fuel oils deals between seller and buyer. My job is to find an able fuel oil Seller for an able fuel oil Buyer. For this job done I was promised commissions for the product delivered. I have currently a Chinese fuel oil Buyer for whom I have found an able Seller. I would like to protect my brokers' interests in any best ways possible. Please, advise on best workable protection banking instruments/documents/etc. which could protect my brokers' fees/commissions to be paid off in full out of such a deal. I appreciate your info and advice rendered.

I recently brought what I thought was 2.75 acres on the top of a hill. During the closing I signed a waiver of survey form with the title company. I later found out that .75 acres of the land I purchase had been dug out from the side of the hill by the adjacent property owner leaving me on 2 acres of buildable land. What can I legally do to be compensated?
