Also practice in general property and commercial law as well.
Disclaimer:
You should seek independent legal or other professional advice before acting or relying on any of the content here or on the internet generally.
There are free legal advice clinics set up in Qld. See link below for locations: http://communitylegalqld.org.au
Also, I am only familiar with the Qld Succession Law so most of my answers are general or based on what I know in Qld. If you are question relates to a different state, I highly recommend that you seek independent legal advice from that state as it is likely to differ from Qld.
Feel free to PM me if you have any confidential enquiries.
I meant more the legal ramifications of accepting an inheritance under false pretenses.
