What happens if you rent your place without a contract

The uncomfortable legal truth: a verbal contract IS valid

Lets start with the fact that surprises almost everyone. In Spain a verbal residential lease is valid (art. 1278 of the Civil Code combined with the LAU). If you reach a verbal agreement with a tenant, receive monthly payments and hand over the keys, there is a tenancy relationship even without paper.

The problem is not validity. The problem is evidence. And evidence is the only thing that matters when something goes wrong. Here are four real cases that show why.

Case 1: Non-paying tenant that took 14 months to evict

Situation: M., owner of an inherited flat in a Spanish provincial capital, rents it to a family acquaintance. Verbal agreement, monthly rent of 650 euros paid in cash. Three years with no issues, until the tenant loses his job and stops paying.

What happened: M. wanted to file for eviction due to unpaid rent (art. 27.2.a LAU). The judge asked for the contract. Without one: (a) she could not prove the exact rent (the tenant claimed it was 400 not 650), (b) she could not prove the start date to calculate arrears, (c) she had to go through ordinary procedure rather than the fast eviction track.

Result: 14 months from the first claim to the actual eviction. Total unpaid debt: 9,100 euros plus costs. Partially recovered because the tenant got a new job: 2,300 euros over 18 months. The rest: uncollectable. With a written contract clearly stating the rent: 3-4 months to eviction plus possibility of a fast small-claims monitorio for the debt.

Lesson: a written contract shortens eviction time and increases recoverable debt. Without paper, everything is argued point by point in court.

Case 2: Damage to the property and no legal deposit

Situation: A., owner of a small studio in Madrid, rents to a young couple without a contract because they were friends of friends. No deposit registered at the regional housing agency because without contract he could not file it. Verbal agreement: 800 euros a month and one month rent as informal deposit handed over in cash.

What happened: when the tenants leave after a year and a half, the flat is left with holes in the walls, stains on the floor, damaged appliances, scratched wooden floors. Estimated repair cost: 4,200 euros.

Result: A. wanted to keep the informal 800 euro deposit to partially cover the damage. The tenant refused, claiming it was not a deposit but rent paid in advance for the first months (without contract, his word weighed the same as the landlords). The landlord had no signed inventory, no dated photos, no documented state of the flat. A legal claim would have required an expert appraisal (1,000 euros) plus lawyer plus court fees. A. chose not to litigate and ate the 4,200 euros himself.

Lesson: without contract there is no legal deposit registered (one month mandatory in habitual residence, art. 36 LAU), no inventory, no documented handover. Any damage claim becomes an uphill battle. With contract plus deposit registered, the procedure is to withhold at the end of the tenancy and return the balance or sue for the difference.

Case 3: Tax agency surprise on undeclared income

Situation: C., owner of three flats inherited from his father, rents one to a relative. Its family, no contract needed.Rent paid hand to hand without receipts. Three years undeclared because family means it is not really a rental.

What happened: Hacienda cross-referenced data from the Land Registry with utility consumption at the flat. The flat appeared inhabited (electricity, water, gas) but was not declared as Cs habitual residence nor anyone elses. A tax inspection followed.

Result: Hacienda concluded the flat was rented out. C. had to declare three years of imputed income retroactively (estimated by the inspector based on market rate: 700 euros a month in the area). Total imputed income: 25,200 euros. Personal income tax plus surcharges plus interest: 5,800 euros. On top of that, no 60% reduction for habitual residence (art. 23.2 of the Spanish PIT law) because he could not prove the tenant had it as habitual residence without a written contract. The relative, additionally, was upset because the rent went up to absorb the cost.

Lesson: Hacienda does not believe family arrangements. Written contract plus tenant census registration plus utility bills in tenants name equals documentation for the 60% PIT reduction. Without contract, the general rate applies to imputed income.

Case 4: Tenant with no payslip and landlord with no guarantees

Situation: L., heir to a small flat on the Spanish coast, rents to a small shopkeeper who lives off his cash business. No contract, no payslip, no guarantor. 600 euros monthly rent handed over in cash to Ls mother when she passed through the area.

What happened: after a year the shopkeeper hits a bad patch and starts paying 300 euros, then 200, then nothing. When L. wanted to sell the flat, the buyer demanded vacant possession. L. tried to negotiate an amicable exit; the tenant refused, claiming I have spent money on improvements, I am not leaving without compensation.

Result: without contract, signed receipts or inventory, L. could not prove (a) that the occupant was a tenant and not a squatter, (b) that the tenancy term had ended, (c) that the tenant had not made the improvements he was claiming. The sale collapsed. L. had to start an eviction by precarious occupation (since without paper she could not even go through the unpaid-rent fast track), a 9-month process that ended with a court-room settlement: 4,000 euros compensation to the tenant to leave. Sale later closed at a small loss due to the delay.

Lesson: without contract you cannot prove the nature of the occupant. They could be tenant, squatter, free-use borrower, lodged relative. Each category has a different procedure and different timeline. Without paper, everything is debatable.

What you DO get with a written contract (summary)

• Certified rent: in court, the rent is the one stated in the contract. No discussion.
• Registered deposit: one month mandatory for habitual residence, deposited at the regional housing body (IVIMA, INCASOL, AVS, etc.). Available for damages at the end of the tenancy.
• Certain term: 5-7 years minimum for habitual residence depending on whether the landlord is a natural or legal person (art. 9 LAU plus Housing Act 2023). Stability for both parties.
• Additional legal guarantees: up to 2 months extra guarantee (art. 36.5 LAU), bank guarantee, joint guarantor. Without contract you cannot require them.
• Inventory and state of the flat: annex document that prevents arguments about who broke what.
• Fast eviction procedure: art. 250.1.1 of the Spanish Civil Procedure Act, oral trial for unpaid rent or expired term, far quicker than the ordinary or precarious tracks.
• 60% PIT reduction: for habitual residence rentals when properly documented.
• Possibility of annual IRAV/CPI updates: mandatory express clause (Housing Act 2023 capped to IRAV).

The minimum your contract must contain

1. Full identification of both parties (name, ID, address).
2. Property description (cadastral reference, address, square metres).
3. Monthly rent in numbers and letters plus payment date plus method (transfer).
4. Term: 1, 3, 5 or 7 years depending on type (LAU art. 9).
5. Deposit: 1 month rent to be filed at the regional body.
6. Rent update clause (IRAV or capped CPI).
7. Expenses: which ones the tenant pays (utilities, community fees if applicable).
8. Annex inventory of the flat and furniture.
9. Place and date of signing. Two original copies signed by both parties.

Thirty minutes to draft, zero euros if you use an up-to-date template. Compared to 9-14 months of eviction proceedings or a 5,800 euro tax assessment: the best legal return on investment that exists.
