1. Ownership of materials not defined

Who owns the material before it’s built into the project? If the contractor disappears, this could become a legal minefield.

2. No obligations for the client

The client’s duties are often forgotten. But without clear responsibilities (e.g., access, documents), the project can easily stall.

3. No clause on work suspension

What happens if the work pauses? Are there standby costs? Do deadlines still apply? Without clear rules, both parties lose.

4. Missing specification of documentation

If technical documents are not described in detail, the result may be far from what the client expected.

5. No liability of subcontractors

If subcontractors are used, and the contract doesn’t define their responsibility, enforcing quality can become impossible.

6. Vague communication methods

“Sends by email” is not enough. Which email? What if the message is unread? Diligent contracts define delivery and confirmation.

7. No governing law clause

In international cases, the lack of governing law and jurisdiction clause can lead to years of legal trouble in foreign courts.
