* Episode 11 of ''FreemansMind'' references this. After he hops over a laser tripwire, a Vortigaunt spawns on the other side of it. After killing it, he shouts:

* Joey and Parker in ''Series/LivAndMaddie'' find it difficult sharing a bedroom so they decide to divide the room in two. Parker claims lower half, and insists that Joey can't set foot on "his" floor. Joey gets round it with a system of ropes and pulleys to move back and forth, and sets up in the top half, insisting that Parker crouch down to avoid invading Joey's space.

* ''Series/FullHouse'', D.J. divided the room she shared with her younger sister Stephanie. Too bad Stphanie's half didn't have access to the door.
* In ''Series/OneTreeHill'' Lucas and Peyton get into a fight and decide to use masking tape to divide the house into with the "no-cross" rule in effect. This cuts off Peyton's access to the kitchen appliances and the house's circuit breakers and Lucas' access to the bathroom and the front and back door.

* ''Film/PacificRim'' has rival scientists [[AdmiringTheAbomination Dr. Newton Geiszler]] and [[GeniusCripple Dr. Hermann Gottlieb]] sharing a room, with a faded yellow line down the middle. Gottlieb is very adamant about this unspoken contract, to the point where if a sliver of a {{Kaiju}} crosses the line, he'll kick it back over.
-->'''Gottlieb:''' No Kaiju entrails over my side of the room! You know the rules! Every bloody day, it's incessant!
* The {{UST}} couple in ''Film/ItHappenedOneNight'' spend the movie hanging a blanket (the Wall of Jericho) between the beds in their hotel/motel rooms for privacy.

* In the ''SteptoeAndSon'' episode "Divided we Stand", Harold and Albert divide the house in two. Even the TV gets divided between them.
* A four-way version happened on ''TheMonkees'' when the four boys were fighting over a girl. The show played with it, noting that each would have access to only one particular vital part of the apartment. Davy's side had the front door, implying he was the only one with the ability to come and go; however, he "would gladly trade Mike for the bathroom right away". Moments later, the whole arrangement is quickly forgotten when a show comes on TV that they want to see and everyone rushes to Peter's side (which contains the television set).

* Happened once in "Anime/{{Pokemon}}" where [[FieryRedhead Jessie and Misty]] fell onto a small rock ledge on a cliff together. Misty draws a line on the rock to give each of them a side while they wait for rescue. Her side is much larger than Jessie's.

* In ''AngelinaBallerina: The Next Steps'', Angelina and Marco did this with a poster after they were assigned to work together. Marco didn't want frills and a tutu on his poster, while Angelina couldn't abide by the idea of having soccer balls in the poster. It didn't work work out, and they went through a couple of other hangups, before finally hitting on a working idea.

* In ''TheSmurfs'' episode "Romeo and Smurfette," Papa Smurf has Brainy divide the village like this when Gargamel starts a dangerous Smurfette/Handy vs. Smurfette/Hefty [[ShipToShipCombat Ship War]]. Seriously.

* On ''WesternAnimation/AmericanDad'', Stan and Francine draw a line across the house after a fight over remodeling the kitchen. It's an InvokedTrope, as Stan comments he saw it on ''TheBradyBunch''. Eventually they build a wall across the middle of the house and a TimePassesMontage shows the family celebrating holidays on Stan's and Francine's side. (It turns out they celebrated all those holidays in one week to make each other feel bad.)

* In ''{{Sixteen}}'', Nikki and Caitlin split their working sides in the mall in "[[FeudEpisode Fish And Make Up]]". [[PottyEmergency This ends up causing problems for the latter later on, due to the washrooms being on the former's side of the mall.]]

* In ''MySistersKeeper'', Kate and Anna did this at one point as children. Kate graciously allowed Anna to choose the side with all of her favorite toys on it, then smiled smugly as she left, since hers was the only side with a door.

* WorldOfWarcraft: Put Horde and Alliance in the same city, and you invetibly end up with this.

* WorldofWarcraft: Put Horde and Alliance in the same city, and you invetibly end up with this.

* Variant: in ''WKRPInCincinnati'', Les Nessman, believing that he deserved an office of his own, used masking tape to mark off an area on the floor of the newsroom around his desk which he claimed to be his "office", and demanded that people "knock on the door" and request entry before crossing the taped line to approach his desk.

* In ''Series/''OneTreeHill'' Lucas and Peyton get into a fight and decide to use masking tape to divide the house into with the "no-cross" rule in effect.

* A story in ''ComicBook/WhatIf: PlanetHulk'' had a one-man version; Hulk lands on the planet the Illuminati wanted him to land on in the first place. Bruce Banner cobbles together a radio to try and get off the planet, but Hulk decided he likes it there so he smashes the radio, which leads to a back-and-forth war of Bruce and Hulk screwing each other over. Eventually Hulk wakes up and sees that Bruce pulled this trope.

* In ''ForBetterOrForWorse'', Mike and Dee's downstairs neighbours complain that there are toys all over the entrance hall, so Mike puts down a line of tape and says they'll keep their stroller, tricycles, etc. on one side and the Kelpfroths can keep their side as tidy as they like.

* Parodied in one ''BloomCounty'' comic strip, when some of the characters start arbitrarily painting lines across the local meadow, cutting off one person each time: "This is ''our'' 'state'! Stay out of our 'county'/'town'/'house'!" Then only two of them are left and they're standing on a hilltop - with no room left for further lines. "You're violating my personal space." Cue the shoving match.
* ''Comicstrip/CalvinAndHobbes'':

** Calvil and Hobbes bickered in the back seat of Calvin's parent's car once.
