Water is collecting in my garden. The last time we emptied it there
was 80 gallons.
My neighbour has a pond and water feature, and my garden is wet near
our boundary, but they deny that their pond is leaking.
How can I prove that the water is coming from their pond?

You can't prove its their water but to get the sort of quantities you are
talking about they would need to be re filling their pond constantly,
so its seems unlikely to be the cause, contact the water company and ask
them to check for leaks if they say there are no pipes or leaks it could
well be natural in which case Mikes suggestion is a good one!
May also be worth checking whether any old drainage systems, culverts and
the like may have become blocked and are there any soakaways or septic
tanks. Sometimes it can all be down to recent buildings going up near
you, it does not take much to alter the natuaral drainage patterns
