Legalisation: what is realistic in the first step
The first step is establishing what physically exists, what is registered, and what can be evidenced.

Legalisation starts with a map of what exists on the plot, not a single form.
Legalisation in Croatia is often treated as one administrative procedure with one deadline. In practice, the first step is always the same: establish what actually exists on the plot, what is registered in cadastre and records, and what can be evidenced by documents or site inspection.
Only with that frame in place do timeline and cost estimates rest on facts. Assumptions in legalisation are expensive.
A typical first step includes: checking cadastral status, comparing it with built reality on site, identifying discrepancies (extensions, use changes, ancillary structures), and mapping existing documents (older designs, confirmations, photographs, contracts).
Only then can direction of procedure be discussed within the limits of the process. Legalisation depends on local practice, building age, use, and quality of existing documentation.
What clients often overlook: legalisation is often a parallel track alongside design, requiring technical documentation of the same discipline as a regular project, with a different starting state.
Our approach: state first, then scope, then a written deliverable with boundaries. Permit timelines are set by the procedure; we document the first step so the next participant knows where the project stands.
