Bring the formation documents, the current capitalisation table, subscription or share purchase agreements, share certificates or membership records, the operating or shareholders' agreement, and resolutions appointing officers. Add the transfer records showing each partner's money entering the company account, since a signed agreement alone does not show funds moved.
Make the paper trail match the story you tell
Where the agreement is still being negotiated, say so plainly and bring the current draft rather than describing a plan nobody has signed. Note any document that names percentages inconsistently — a term sheet saying sixty-forty and a certificate saying fifty-fifty invites a question. Missing items can often be supplied later, but the reviewer should know now which records exist, which are pending, and who controls them.
Request the entity documents, the asset list with titles for vehicles and equipment, the premises lease and its assignment terms, the service contracts and whether they survive a change of ownership, and any liens registered against the assets. Several years of financial statements and tax filings, payroll records showing real employees, the equipment list with titles and valuations, the customer contracts, the lease, and any licences the business holds.
Put both leases into a single table showing monthly rent, remaining term, renewal option, and the cash actually committed to date.
