The Law Institute of Victoria has a Find a Lawyer service which lists lawyers who specialise in this area of law.
These are not free services.
The Find A Lawyer service can refer you to up to three private lawyers who can provide a 30 minute interview at no charge so that you can work out if they are the right lawyers for you.
Some lawyers may offer a discount, depending on your circumstances, or charge on a “no win, no fee” basis. You can ask the legal firm about this directly.
