13 monthsto return a debit without a mandate

This guide refers to owners' communities (comunidades de propietarios) in Spain.

An owner sells their flat, the buyer keeps paying from the old account for a while and, months later, the bank suddenly returns a whole series of debits. Nobody had signed a new mandate.

Direct debit is the most effective tool against arrears, as long as it's done properly. This guide explains the building blocks of the SEPA system and the mistakes that cost a community the most.

What a SEPA direct debit is

It's the European system that lets a creditor (the community) collect euro payments directly from the debtor's account (the owner's), with their prior authorisation. In Spain it's processed using the Spanish Banking Association's batch format (AEB Cuaderno 19).

There are two schemes:

Scheme	For whom	Refund by the payer
SEPA Core	Any debtor, including consumers	8 weeks with no reason needed if authorised; up to 13 months if not
SEPA B2B	Businesses and self-employed only	No right to a refund of an authorised debit

Communities collect from private individuals, so they use SEPA Core.

The 4 building blocks a community needs

Creditor identifier. The code that identifies the community as the issuer of the debits. The community's bank assigns it based on the community's tax ID. The firm's identifier must not be used: each community collects in its own name.
A mandate signed by each owner. This is the authorisation. It must include at least the unique mandate reference, the creditor identifier, the debtor's details, their IBAN, the payment type (recurring or one-off), the date and the signature.
Pre-notification. The debtor must know the amount and date of the debit at least 14 calendar days in advance, unless another period has been agreed. Sharing the annual fee calendar covers this obligation for recurring debits.
Batch submission to the bank in the format and timeframes your bank specifies.

Refund periods, no small print

Authorised debit (valid mandate): the owner can request a refund for 8 weeks from the debit date, without giving a reason.
Unauthorised debit (no mandate or a defective mandate): the period extends to 13 months.
Keeping the mandate: for as long as it's in force and for at least 14 months after the last collection.

In practice: a badly signed mandate turns an 8-week refund window into a 13-month risk.

The 6 most common mistakes

Mistake	Consequence	How to avoid it
Collecting with a noted-down IBAN but no signed mandate	Refunds possible for up to 13 months	Signed mandate (on paper or e-signed) before the first debit
Not requesting a new mandate after a sale	Debiting someone who's no longer the owner	Set up the mandate as part of the change-of-ownership process
Using the firm's identifier	Ownership and reconciliation problems	A separate identifier for each community
No pre-notification	Grounds to dispute the debit	Annual calendar shared with everyone
Special levies collected without notice	Chain of refunds	Communicate the amount and dates of each instalment
Not checking returns daily	Non-payment detected weeks late	Frequent bank reconciliation

After collection: reconciliation

Collecting isn't the end. Each bank movement has to be matched with each debit issued to know who has paid and who has returned it. Spanish banks provide statements in the AEB Norma 43 format, which makes it possible to automate that matching instead of doing it by hand, debit by debit.

Where Wabee is heading

The collections module we're building covers the whole cycle: fees issued by ownership share, SEPA batches with each community's real creditor identifier, an automatic payment calendar, special levies, Norma 43 reconciliation and a real-time treasury view. When a debit is returned, the system detects it and triggers the first reminder without waiting for month-end.

Frequently asked questions

Who has to sign the mandate? The holder of the account the debits are charged to. If a third party pays (a relative, for example), that person signs, although the debt still belongs to the owner.

Is an electronically signed mandate valid? Yes, as long as it can prove the debtor's authorisation. What matters is being able to show it if the bank asks.

Can an owner return a debit even if they owe the fee? Yes, within the 8 weeks. The refund doesn't cancel the debt: the fee remains outstanding and is claimed through the usual route.

Do mandates have to be renewed every year? No, they stay valid as long as they're used. But a mandate with no debits for 36 months expires and a new one must be signed.
