So if you are really in the situation where you have set deadlines, they have passed and now you are commissioning someone else. Or there is still money due, but work is still outstanding, the general contractor goes bankrupt.
Well, quite specifically. I have been living in the house for about 30 months. At the handover, defects or unperformed services were still identified. The house was handed over, the final installment was reduced by €10,000. I could simply do that because my money is in my account. Since then, I have pursued this with varying degrees of pressure, and in the meantime new defects have appeared. The fact is, to this day not all defects have been fixed and not all missing services have been provided. So I still have my €10,000, which I will only pay once everything is finished. And if it gets too much for me, I set deadlines and, if necessary, I carry out a substitute performance; I then pay the new craftsman with my €10,000 and the matter is settled.
How would it be if the €10,000 was held in escrow at the bank? I might not have the money for a new craftsman. Above all, I would have to worry about how I would ever get my €10,000 back. Because for that I need the consent of the general contractor. If he is stubborn and simply refuses, in the end only a lawsuit for approval remains. Years later, the judge tells me who has to bear which defect or not to what extent and how much money I get back – minus all court costs. But maybe that will only be told to me by the second or third judge if the general contractor is bored and just as persistent. And during all those years, I would not get into repaying the loan because it is not fully disbursed yet, so I end up paying commitment fees – which for me, concretely, are exactly six times as high as the loan interest.
When I have thought about all these things, then I quickly tend to release payment despite defects in order to sue to get my money back afterwards. And that is where the loop turns, see above.
Now you can expand the story as you like. A speeding-up factor in the decision process would surely be that the general contractor does not install the roof before the outstanding installment is paid and thus construction damage threatens. Or just come up with something yourself. A good contract is concluded on equal footing with mutual trust. That is already out of balance in construction anyway.
