Ownership and control evidence for both entities, plus operational evidence that each is actively trading. Share registers, articles and organizational charts establish the relationship; invoices, contracts, payroll, tax filings and bank activity establish the business.
Two stacks of paper, doing two different jobs
Separating the stacks makes the weaknesses visible. The relationship stack contains articles of incorporation, share registers or membership certificates, any shareholders agreement, and a chart showing the ownership line from the Bonfield company to the U.S. entity.
The activity stack contains signed customer contracts, issued and settled invoices, payroll registers, equipment leases, operating authority and insurance certificates, and filed tax returns showing revenue. Ingrid's own stack sits alongside both: dated employment letters, payroll history covering the qualifying year, and a chart showing who reported to her. Where a document does not exist, the answer is to say so and choose a filing strategy that fits the real facts.
An adjudicator who finds an evidence gap has found it; an adjudicator who finds a manufactured document has found something worse.
