Party / boundary fence

I think the Gardai would be sympathetic in your particular circumstances and might be willing to have a word
 
Thank you.

I did contact the Garda but they never came.

Did you call directly to the station? Most of them have a community officer who are generally very understanding. They offer advice even if they can’t intervene directly.
 
Your neighbour sounds like Donald Trump in his determination to build that fence except that you are not going to be the one to pay for it !!

Your first priority is to create a picture collection of what is there now before the evidence is destroyed.
If possible, also take pictures from upstairs to show context.
When taking pictures imagine that you taking them for the benefit of a judge who will need to get a clear understanding of what is in dispute.

Deeds do not seem to contribute much useful information in boundary disputes.

The fence is either a boundary fence or a party fence.
If it is your boundary fence "Donald" has absolutely no rights to touch it.
If it is Donald's fence you have no rights even though you have contributed by maintenance.
If it is a party fence your interest in it means that Donald has to reach agreement with you before acting.

Although 99% certain it is not there see if your title deeds include a party wall agreement. If there is one check that the previous signatories to it drafted it such that it binds subsequent owners.

Did you buy from developers or from a previous owner ? If a previous owner see if they can be contacted with a view to seeing if they have any useful evidence to offer. Otherwise, you may well need a solicitor to do some searching through the title deeds to see if they yield any information on this subject in the context of what was conveyed. For example, our house was built on land demised from a religious order who required the developer to build a boundary wall which was conveyed to my parents as a boundary wall.

Telling you to f*** off is just unacceptable. It is typical of the type who likes to expand their boundaries in a "land grab" type of operation.
Tell the neighbour that you might need to seek an injunction if he starts up again with his threats.
