Share purchase agreement workflow

The SPA is the contract that turns a term sheet into a closed deal. Getting the risk allocation right — warranties, disclosure, indemnities, and the purchase price mechanism — is what separates a clean exit from a costly dispute.

In short

This is an 8-step workflow for drafting and negotiating an Australian private company share purchase agreement (SPA). It covers due diligence, consideration, warranties, completion, and post-completion adjustments.

Time: 40 to 200+ hours depending on deal size, competitive dynamics, and diligence complexity.
Audience: Australian commercial M&A lawyers acting for a buyer or seller in a private company share sale under Australian law.

Tools: Data room, DD checklist
3

Draft consideration and purchase price

Draft the consideration mechanism — fixed, locked box, or completion accounts — with adjustments for working capital, debt, and cash. Align with the term sheet.

Tools: Quillio
4

Draft warranties and indemnities

Draft the warranties schedule covering title, authority, financials, tax, compliance, litigation, employees, and IP. Draft tax and specific indemnities as needed.

Complete and settle post-completion

Outcome

What you will have at the end

A signed and completed share purchase agreement transferring legal and beneficial ownership of the target shares, with a clear warranty and indemnity regime and all regulatory gates satisfied.

Common issues

  • Locked box drafting that does not clearly allocate leakage risk
  • Warranties schedule over-relying on knowledge qualifiers
  • FIRB path not identified early enough, delaying completion
  • Disclosure letter and data room inconsistency
  • Post-completion adjustments missing an agreed dispute process
