Supreme Court deed poll records

There is now a 100-year restriction (it used to be only 30 years) on access to Supreme Court deed poll records at Queensland State Archives - but you may be able to apply for access to restricted records via Right to Information. Start by reading the Research Guide to Court records, on the Queensland State Archives website. (They periodically change the website address, so I won't put a link here. You'll find it easily with a Google search.)
