Retrieval and reconstruction. Registry searches, accountants' archives and old share transfer records come back on their own schedule, and family recollections often need reconciling against documents. The drafting that follows is comparatively quick once the underlying record has been settled.
Start the retrieval before anything else
Put the registry and accountant requests in on day one, because everything downstream waits on them. While they run, build the honest structure chart and collect the authority traces already in hand. Set a review point once the corporate position is confirmed, and keep commercial decisions — a new hire, a lease, a relative's resignation — behind it.
Approval, visa issuance and admission remain separate steps with separate timing. One further item usually sits on the critical path and is easy to start late: reconciling what relatives remember against what the documents show. That reconciliation takes calendar time rather than working time, because it requires several people to look at the same records and agree, and in a family business those conversations are rarely scheduled.
Set a date for it, name who attends, and hold it once the registry and accountant material has arrived. Everything downstream, including the duty narrative and any filing date, waits on that meeting rather than on the drafting that follows it.
