Tenant Screening in Portugal: What Landlords Can Legally Check (2026)

Tenant screening — verificação de inquilinos in Portuguese — means checking a candidate's identity, income and rental history before you sign. In Portugal it carries unusual weight: terminating a lease for non-payment generally requires arrears of at least two months (Art. 1083º CC), the tenant can stop the process by paying what is owed (Art. 1084º CC), and a contested eviction routinely takes many months from the first missed payment to recovered keys.

The law does compensate you for late rent — Art. 1041º CC allows a 20% indemnity on the overdue amount once an 8-day grace period has passed — but an indemnity is only worth something if the tenant can pay it. Screening works earlier, before the contract exists, when you can still simply say no. It is the cheapest protection a Portuguese landlord has.

Portuguese law draws the line in two places: anti-discrimination rules and data protection.

You may lawfully ask for what a solvency decision genuinely requires:

What is off-limits is just as clear:

A solid screening for a Portuguese tenancy covers four checks:

The standard affordability benchmark is the 3x rule: net household income of at least three times the rent. If the rent is €900, look for combined net income of roughly €2,700 per month. Treat it as market practice, not law — nothing in the NRAU or the Civil Code imposes an income ratio. A candidate at €2,400 with a permanent contract and a strong fiador (guarantor) can be a better risk than one at €2,700 in a precarious job.

Where income alone is not convincing, the lawful reinforcements are a guarantor or the security deposit — capped at two months' rent (Art. 1076º CC).

CompliantLease generates NRAU-compliant Portuguese leases today, with deposit, guarantor and late-payment clauses that cite the exact articles they rely on (Art. 1076º, Art. 1041º CC). Tenant-screening reports arrive at launch: income verification combined with a creditworthiness check based on a Banco de Portugal credit report that the candidate uploads themselves — so the applicant stays in control of their own data, as the RGPD intends. The waitlist is open.
