A person has worked as a programmer in a company ; But the company did not pay its dues ; In that case, he can sell some of the company's programs to earn his own money ? I used to work as a programmer in a company on a monthly basis. After four years of service, I quit my job. But I did not receive my full payment from them ; Although they promised me. Then they asked me to do some programming work on the system that I had developed for them earlier . For this they will pay me extra and also pay the previous dues. They will own these naturally produced content and programs. I agreed as a step to recover my dues from them. After ten months I handed over the tasks in full. From then on, they no longer receive my calls. Later I found out that they had sold the system I had developed and set it up with a few customers and some government agencies. In this way they are selling. My question is: since they have broken the contract and have not paid their promised amount, will these programs be considered as my property ; So that I can sell it and get halal profit. These programs include some of the ones I developed during my tenure.
