Do you mean "Breach of Contract"?
In the old days a "man was as good as his words", which meant you didn't need anything more than agreement and a hand shake. No contract. No video tape. No witnesses.
Sounds like you had a 3 party deal. (you, land owner, contractor) At a later date, there was a subsequent 2 party deal (with you on the outside looking in)
This is why shotguns and lawyers were invented.
To make your arrangements enforceable, you should have a written, signed contract. Otherwise, it's your word against his if you try to hold him to the agreement.
With a written, signed, notarized contract, you can sue and win unless there are valid, legal reasons why the contract is not enforceable.
I have some clients that came to me and ask me to provide them as service, they ask what I provided and agreed to terms, verbally in front of witnesses. The service I provided was logistics for locating a logging(harvest) contractor. I brought them their contractor and also told him the situation, he agreed to work for a set price, again verbally in front of a witness. Afterwards, the contractor leaves and comes back when he thinks I am unaware, ask the landowner to work with him and cut me out, the landowners agree and now the job is complete, what can I do? I live in Angelina co Texas. and also I am in a very similar situation also, but under contract, If someone could help, it would be greatly appreciated. Thanks, Kenneth
