So an attitude from the architect really gives the whole thing a bitter aftertaste, I didn't expect that. Of course, we only know the situation from one side, maybe the family is actually the client from hell, but it doesn't seem that way to me. If the architect now comes with reluctance, I would really make a lean offer. Here, 5k or we'll see each other in court, please, thank you. In return, he should hand over all the work done. The whole process wasn't worthless after all, so don't try to get upset, but see it as a not entirely cheap crash course on house planning.
