Dear all, may help advise me.

Below event in chronological order.

1. Submit reno plan for approval. (still pending)
2. Contractor say can start work after submit, which is not true. Receive saman letter, asked to pay before plan can be approve. PAID
3. Renovation continue as is. Received back APPROVED reno plan.
4. House already done.

I think i miss step where need to inform to start work after getting approved plan (which i started in already and kena saman).
Also is there a step to inform when completion?

Right now what i have is just an approved plan and no othe
