Surcharges of 10% despite a fixed price contract

If you already show up with a lawyer at the construction company before construction begins, these are the best conditions for a smooth contractual relationship.

That is why it is only legal advice without the lawyer intervening. Otherwise, how is a layperson supposed to respond to such a demand in a formal legal manner?

The 10% is annoying and not insignificant. Apart from the fact that a lawyer's letter forms an optimal basis for a trusting cooperation, the price increases are a problem. What is happening at the moment could not have been foreseen by anyone. The entrepreneur has no choice but to pass on price increases as much as possible or ultimately face insolvency.

I would be repeating myself if I mentioned something about the lawyer's letter again...
I wouldn't want to make it that easy for companies; it is clear the situation is not foreseeable, but there are contracts and an entrepreneurial risk. In the future, such price guarantees will of course no longer be given so easily.

Of course, there is a business risk. The risk ultimately means insolvency and for you an unfinished construction. That must also be taken into consideration.

The question of how long the price commitment is valid according to the contract is still open.

Of course there is a business risk. The risk ultimately means insolvency and for you an unfinished building. That must also be taken into account.

It's not quite that simple, a company usually also strives to avoid insolvency – it's not only possible to charge this at the expense of the customers. But of course, I understand that one should make a concession in such a case. A concession of 10% is however quite harsh..
