Key takeaway: This checklist helps you spot common abusive terms, but viability depends on how each clause was drafted and explained. A deed review is the fastest way to confirm what is actually claimable.

IRPH legal context (recommended):

• EU ruling on IRPH-linked mortgages (what it means)
• CJEU ruling on IRPH mortgages (refunds: key points)

1. Floor clause (mínimo de interés)
   Often worded as “límite a la variación del tipo de interés”. Courts frequently consider it abusive for lack of transparency, especially where the floor–ceiling balance protects only the bank. For new mortgages, stronger pre-contract transparency duties limit its use.
2. Multi-currency clause
   Can be partially null where the lender failed to clearly explain risks (exchange rate impact, capital re-denomination, negative amortization scenarios). Case-by-case analysis applies.
3. IRPH clause
   Still subject to transparency control. Publication in official sources is not enough; banks must explain index mechanics, historical evolution, and alternatives. Spanish courts review case by case.
4. Upward rounding clause
   Always rounding the rate upward (e.g., to the next 0.25%) is typically unfair for creating a one-sided imbalance and not being individually negotiated.
5. Interest review only upon borrower request
   Making variable-rate resets depend on a borrower request distorts the contract’s mechanics and has been invalidated.
6. French amortization system
   Not abusive per se. It amortizes capital with each payment and interest falls as outstanding capital falls. Problems arise from poor transparency (e.g., missing amortization tables), not from the method itself.
7. 360-day interest base
   Not automatically abusive, but must be clearly disclosed. Vague wording (e.g., “commercial days”) without the actual formula can be unfair.
8. Default interest (intereses de demora)
   For residential mortgages, default interest is capped at the remunerative rate + 3 percentage points, with no compounding. For non-mortgage consumer credit, excessive rates can still be deemed unfair.
9. Anatocism (interest on arrears interest)
   In mortgages, arrears interest cannot be capitalized to become principal.
10. Abusive imposition of personal guarantors
    May be disproportionate when the risk is already covered. Transparency is especially lacking where guarantor waivers are inserted without explanation.
11. Waiver of excussion, division, and order by guarantors
    These waivers place the guarantor on the same footing as the borrower and are often null when their consequences were not clearly explained.
12. Mortgage expenses clause
    Shifting all costs (notary, registry, appraisal, gestoría, certain taxes) to the borrower has been declared abusive. After nullity, costs are re-allocated according to the law in force at the time; recovery depends on invoices and deed wording.
13. Bank’s legal fees in case of litigation
    Blanket terms obliging the borrower to pay the bank’s legal costs are null for creating imbalance and limiting consumer rights.
14. Opening commission
    Valid only if it corresponds to a real, individualized service effectively provided to the consumer. Otherwise, it can be unfair.
15. Study commission
    Transferring internal study costs to the consumer without a specific service may be abusive.
16. Subrogation commission
    As with the opening commission, it must reflect an actual service and be transparent; otherwise it is unfair.
17. Reference to the bank’s tariff book
    Referring to an internal “fee book” without concrete figures given to the borrower at signing is abusive. Pricing must be clear and delivered directly.
18. Postal/notification expenses
    Generic postal costs imposed on the consumer, without fair distribution or proof of service, are typically unfair.
19. Commission for claiming debtor positions
    Must be in the contract, linked to a real collection action (not a generic letter), not repeated for the same debt, and fixed (not proportional).
20. Early maturity (vencimiento anticipado)
    Statutory triggers apply: as a rule, in the first half of the term at least 12 months or 3% of principal unpaid; in the second half, at least 15 months or 7% of principal unpaid. Courts also require proportionality and a cure period.
21. Clauses limiting ownership rights
    Broad bans on selling, leasing, or encumbering the property without lender consent are often null for unduly restricting ownership.
22. Ban on professional use
    Unjustified limits on using the property for professional activity may be null.
23. Waiver of notice on loan assignment
    Waiving the right to be notified of a loan assignment can contravene consumer-protection rules.
24. Executive power for notarized copies at the bank’s request
    General waivers granting executive force to any copy without borrower acceptance are problematic and often void.
25. Appraisal value for auction
    Auction bases must respect legal floors (e.g., not less than 75% of the appraisal when applicable). Adjudication to the creditor, if no bidders appear, must also meet minimum statutory percentages.
26. Compensation for loss and lender-placed insurance
    Unnecessary where the law already grants the creditor certain rights. Terms allowing lender-placed insurance at the borrower’s expense are generally abusive.
27. Choice of notary
    The consumer has the right to choose the notary (with reasonable connection). The notary must advise the weaker party. Current rules reinforce mandatory pre-signing notarial guidance and standardized information.
28. Express submission and waiver of proper jurisdiction
    Jurisdiction waivers contrary to protective civil-procedure and consumer rules are prohibited.
29. Product tying clauses
    Tying is restricted. Bundling is only acceptable when it benefits the consumer and is fully transparent (e.g., genuine discounts) and the optional nature is clear.
30. Compound interest clauses (general)
    Outside arrears interest (which cannot compound), compound interest must be clearly agreed and explained; opacity can render it unfair.
31. Interest-rate “hedge” add-ons
    Embedded hedges or compulsory protections can be unsuitable or non-transparent. Courts assess borrower profile, pre-contract explanations, costs, and breakage risk.
32. Evolving jurisprudence
    Interpretation keeps evolving with new rulings and regulatory changes. Always test clauses against the rules and case law in force at signing and at litigation.
33. Protect your rights
    Keep your deed, pre-contractual documents (FEIN/FIAE), offers, statements, and appraisals. If you suspect unfair terms, seek legal advice to assess potential recoveries.
