Who Owns the Couch: Splitting Shared Purchases
The couch problem is simple to prevent and genuinely hard to fix afterwards. Three people split the cost of a sofa, a year passes, one person leaves, and there’s no agreement about whether they get a third of what it cost, a third of what it’s worth now, or nothing. The fix is a one-page shared inventory and a rule agreed before you buy anything: whoever wants to keep an item buys out the others at an agreed depreciated value.
Here’s how to set that up and how to handle the awkward cases.
Decide the buying rule first
Before your first shared purchase, agree how shared buying works at all:
- A spend threshold. Anything over an agreed amount — pick a number, $30 to $50 works — needs everyone’s yes before it counts as shared. Below it, just log it. This is the same threshold rule that keeps your shared expense ledger uncontentious.
- Nobody buys a shared item unilaterally and then invoices the household. A vacuum bought without asking is the buyer’s vacuum.
- Agree the exit rule before you buy, not after. One sentence: “if one of us leaves, whoever keeps it buys out the others at half the purchase price in the first year, a quarter after that.” The specific formula matters far less than having one.
Keep a shared inventory
One page in your shared documents. Add a row when you buy something shared.
| Item | Date | Cost | Paid by | Split | Notes |
|---|---|---|---|---|---|
| Sofa | Sep 2025 | $600 | Dana $600 | 3 ways | Dana fronted; Priya and Marco reimbursed $200 each |
| Vacuum | Sep 2025 | $140 | Marco | 3 ways | |
| Coffee table | Nov 2025 | $80 | Priya | Priya + Dana | Marco opted out |
| Microwave | Jan 2026 | $95 | Dana | 3 ways |
Four columns do all the work: what it is, what it cost, who actually paid, and who it’s split between. The “who it’s split between” column matters because not everything is bought by everyone, and that’s fine as long as it’s written down.
Photograph anything expensive on the day it arrives. Condition at purchase is what you’ll want at buy-out time.
Three ways to divide it at move-out
Pick one at the start and write it into your roommate agreement.
1. Depreciated buy-out. The fairest and most common. Whoever keeps the item pays the leaver their share of a reduced value, on a schedule agreed up front: half of purchase price in the first year, a quarter after two, nominal after three. Being arbitrary in advance is what makes it work — nobody’s arguing about what a two-year-old sofa is really worth.
Example: the $600 sofa, split three ways, is 18 months old. The household’s schedule says a quarter of purchase price after a year: $150. Marco is leaving; his third of $150 is $50. Dana and Priya pay him $25 each and keep the sofa.
2. Nobody owns anything. Shared purchases are treated as consumed the moment they’re bought — a cost of living there, like electricity. No buy-outs, no inventory arguments. Whatever’s left when the household dissolves gets sold or given away, and the proceeds split.
Cleanest option by far, and appropriate for cheap items and short tenancies. It stops being appropriate as soon as somebody’s contributing hundreds of dollars.
3. Individual ownership, shared use. Nobody splits anything. Each person owns what they bought and takes it when they go. Zero ambiguity, and the risk is that the household loses its sofa on a week’s notice. Works best when everyone brings furniture with them.
The specific awkward cases
Somebody fronted the money and was never reimbursed. Then it’s their item, not a shared one. Log reimbursements the day they happen — a shared purchase where two people never actually paid their share is the most common version of this dispute.
The item is worth almost nothing but somebody wants it. Let them have it. A twenty-minute discussion about a $40 bookshelf costs more than the bookshelf.
Nobody wants it. Sell it and split the proceeds by the original shares, or give it away and log that it’s gone. Don’t leave it for the next tenants or in a shared hallway.
The household is dissolving entirely. Go down the inventory row by row: who wants it, at what value, and who’s owed. Fold the whole result into a single set of transfers, so nobody is sending five separate amounts — see the final settle-up when everyone moves out.
A shared item breaks. Agree the principle in advance: normal use failure is a shared loss, and damage caused by one person’s misuse or by their guest is theirs. That’s the same ladder you use for the security deposit, so keep them consistent.
It’s the landlord’s, not yours. Furnished properties come with an inventory of items you don’t own. Damage to those is a deposit question, and how deposits and damage are handled varies by lease and by location — check your lease and your local rules rather than assuming.
What not to buy jointly
Some things generate more argument than value:
- Anything one person clearly wants more. A games console, a bread maker, a specific style of lamp. Let them buy it; let everyone use it.
- Anything expensive with a long life. A washing machine outlives most tenancies and is genuinely hard to divide at move-out. Better for one person to own it outright.
- Anything hard to move. Bulky joint furniture is nobody’s problem right up until it’s everybody’s problem on the last day.
Cheap, consumable, universally used — split it. Expensive, durable, personal-taste — one owner.
Checklist
- Spend threshold agreed for what counts as a shared purchase
- Exit rule chosen and written down before the first purchase
- Depreciation schedule agreed, if using buy-outs
- Shared inventory started, one row per item
- Reimbursements logged on the day they happen
- Photos of anything expensive, taken on arrival
- Breakage principle agreed: normal failure shared, misuse individual
- Landlord’s own inventory kept separate from yours
- Inventory reviewed whenever someone moves in or out
Write the rule and the inventory location into your roommate agreement, and check the inventory as part of any roommate change — see when a roommate wants to move out early.
One note: this is guidance on being fair between roommates, not legal advice. How shared property and deposit deductions are treated can depend on your lease and your local law, which differ everywhere — check both, and get proper advice if a real sum is in dispute.
