The Long Limb of the Law - Getting the Job Done seminar will cover issues from health and safety to tree protection.
Consultant and tree-hazard expert Dr David Lonsdale will talk about the Felbrigg Hall civil case, where an 11-year-old boy was killed by a falling branch at National Trust property Felbrigg Hall, near Cromer in Norfolk.
Last year, a high court judge rejected a claim that the trust's tree inspectors failed to exercise reasonable care in their task.
Dr Lonsdale will talk about the implications for tree experts and landowners.
Meanwhile, planner Dr Charles Mynors will give a rundown on recent law changes affecting arboriculture. Arborist Peter Annett will explain what is new with tree preservation orders.
The event, hosted by the East Anglian Tree & Landscape Officers Group, will be held at Christchurch Park Mansion in Ipswich, Suffolk, on 6 February.
