Contracting without defining the fees
I was contracted by two individuals who represented a group of inheritors to file an inheritance case on their behalf which involved selling a building for them here in Egypt. Due to unforeseen circumstances and a severe dispute between the inheritors on one hand, and the inheritors and the buyer on the other, we were not able to reach an agreement regarding my compensation, and after I succeeded in acquiring for them a large sum I was not paid. What are my rights upon the agents and the inheritors, bearing in mind that we did not agree on my payment in the beginning?
If the case is as mentioned in the question, that the inquirer concluded a contract with the agents without defining the remuneration and accomplished his task, we yield to customs and followed procedures adopted by professionals in this field. If this is not possible, he must take legal action against them in order to protect his rights in an appropriate manner.
Allah Almighty knows best.
