BÜ wants a declaration of assignment. How to avoid it?

I also deal professionally with clients who want to have every little detail evaluated by an expert, instead of accepting that some standards and measures are absolutely within the quality standards, even if the layperson does not see it that way.

I can also say that I deal with many citizens who, in their view, should be granted more attention and/or rights than they are entitled to under rights and laws. It is often a fine line between insight after a thorough explanation and the subjective feeling of being taken advantage of. Not easy at all for the person affected.

And yes, I also know that construction companies involved are often not motivated to do proper work without the leverage of retention of payment. And even then, often not enough. With full order books and the general situation in construction, all of this is getting even more serious. I would therefore also have it examined how the clause can still be countered.

It is logical that we are not looking for a dispute, but want to complete our house and carry out the construction process as smoothly as possible.

Then don't drive the relationship with the contractor into the ground.

Still wanted to have a plan B for what options we have if the managing director does not cooperate / blocks our proposals, etc.

Well, honestly: in your other thread we made it clear to you that your demands are not really in accordance with the contractor agreement. I really don't know now what you mean by blocking or cooperating.

Then don’t drive the relationship with the BU into the ground.

Well, honestly: in your other thread, we told you that your demands are not really in line with the contract for work and services. I really don’t know what you mean now by blocking or accommodation.

That is very clearly stated in my opening post. Slowly, this apparent smart-ass attitude is getting on my nerves. I would gladly like to see you in the role of signing some crap that gives the BU full rights to freely decide over the funds provided by the bank. What if he is close to insolvency? So please. This is not about some school-level disputes, but about a really nasty matter that gives the BU a very clear advantage and us a very clear disadvantage. And if one cannot contribute anything concrete from experience on the matter, then better stay out of the topic altogether than with pointless comments like "it’s your own fault," "you are suspicious," blah blah. Yes, we are. And everyone who handles such sums should be! I really don’t understand neither this tone nor this strange view that we ourselves influenced this demand.

but rather about a really nasty thing that clearly gives the BU an advantage and us a clear disadvantage.

This apparent smartass behavior is slowly getting on my nerves.

People who do not admit they are wrong or make mistakes also get on my nerves. Especially when they forget overnight. Nevertheless, I do not lose patience. You are not the only one who wants to build and has signed a work contract. It is what it is. People make mistakes and own up to them.

signing some nonsense that gives the BU full rights

Quite matter-of-factly: A more or less standard contract with a general contractor was signed. This contract includes a clause that protects him in case of delayed payment by the client. He has now made use of this clause because the conditions have been met. That is his right. Whether the last sentence is lawful in this consequence could be the only matter, among all the previously described facts, where it might not be entirely clear. Otherwise, the GC is acting completely legitimately and understandably. In my opinion, the money for a lawyer would not be very well invested in this case. The risk here is significantly greater than the profit you could expect.
