Understand lease length, valuation assumptions and professional costs.

Start with a careful definition

Understand lease length, valuation assumptions and professional costs. This guide is designed as a research checklist, not an assessment of whether a particular person has a viable claim or entitlement. A useful first step is to separate what is documented from what is assumed.

What changes the answer?

The 2024 reform legislation has provisions not yet commenced: do not assume the new valuation or marriage-value rules already apply. The practical answer can depend on written contracts, records, chronology, local procedures and the advice of a qualified professional. Avoid relying on a headline alone.

Documents and facts to organise

Questions worth asking

  1. What is the key document or rule to confirm for what influences the lease extension premium?
  2. Which deadlines, costs or eligibility conditions depend on the location and facts?
  3. What would a suitably qualified professional need to review before giving advice?

Comparing next steps

Ask providers to explain their jurisdictional experience, who will handle the work, their fee structure, their approach to disputes and what they cannot yet determine. A comparison should be based on written terms, not rankings or promises of success.

Jurisdiction note
