VIC Property boundary shift after refencing

[Gabriele]

Hello,
A little while ago our neighbor asked us to consider changing the boundary fence. We agreed and paid half. However, the boundary line has changed post the new fence installation. Where do we look for assistance in rectifying the situation - who would be an arbiter, who would pay for the inspection and the new fence construction, if appropriate.
Many thanks
Gabriele

Talk to the fencer in the first instance to see why he moved the fence line.
