It does tend to depend on the property as to whether your solicitor can categorically state which boundary belongs to which property.
Easier on modern/new builds but not quite so cut and dried with older properties.
The given used to be that if the nails supporting your fence pointed towards your land, the fence was yours. However, modern fencing companies don;t always follow this rule so it can be a bit of a sticky issue.
If all else fails, a rule of thumb would be that as you look out onto your garden, the Right hand boundary would "normally" be yours. I put that in quotes as it doesn't always follow.
Boundaries are a minefield and quite often the Legal Eagles ( aka conveyancers ) often have no more idea than you and I
If you are lucky and your neighbours listen to reason, you should be able to sort it without resorting to further measures.
