Now I want the money back, he agrees, but I want to somehow verify it on paper, some contract, for example, that he sends me 1000 CZK every month. So that he wouldn't give me CZK 500 now, he said yes, I'll give you the rest in a month and the deed will escape .... If he didn't send it, I would take the contract to court and they would get it from him. What contract should I prepare? Please advise me.
