Justin Theroux, who has been living on his own without estranged wife Jennifer Aniston, is fighting with his New York City neighbor in a bitter feud over alleged trespassing.

The issue is a common one in crowded Manhattan. It has to do with apartment renovations.

The 46-year-old actor, who split from Aniston earlier this year, has accused neighbor Norman Resnicow of coming onto his property without his permission eight times since May 2017, according to court papers.

Theroux charges that a security camera caught Resnicow illegally trespassing on his property twice in March and once in April, which he says he personally witnessed.

The incident involved a confrontation. Resnicow allegedly “erupted that I was mistaken and that he was not trespassing (though he was). To avoid an unpleasant confrontation, I returned back into my apartment,” court papers examined by TheBlast claim.

Theroux has asked the court to find his neighbor liable and to determine damages at a subsequent date.

Theroux and Resnicow have had a strained relationship for some time. The actor sued his neighbor in 2017 over renovations to Theroux’s Greenwich apartment.

Theroux accused Resnicow of threatening to cut of his water and electricity, while also warning the movie star that he would launch a PR campaign against him if he failed to sound-proof his abode.

However, Resnicow subsequently filed a countersuit, accusing the “Zoolander 2” actor of terrorizing him and his wife with his unreasonable behavior.
