Signing an affidavit of heirs in Spain

The affidavit of heirs makes it possible to formally establish the status of heir. In Spain, this formality exists, but its use and conditions differ from those applied in France. 

Signing an affidavit of heirs in Spain
Succession and inheritance

In a succession involving Spain, it is essential to determine whether this document is required and, if so, where and how it must be drawn up.

Purpose of the affidavit of heirs in Spain

The affidavit of heirs is used in particular:

  • to identify the legal heirs,
  • to specify each heir's succession rights,
  • to secure the subsequent steps (notary, banks, public authorities).

Where and how the document is drawn up

In practice, the document is drawn up:

  • before a notary,
  • in the town of the deceased's last residence or in a neighbouring town,
  • with the participation of witnesses who knew the deceased.

Time limits and effects

The document is not immediately effective. Its enforceability and its practical effects may be subject to procedural time limits, which can influence the overall timetable of the succession.

When the affidavit of heirs is not required

Where the deceased left a registered and usable will, the approach is different. In a number of situations, the affidavit of heirs is not required, or a document drawn up in the State of the deceased's habitual residence may be sufficient, depending on the case and the available documents.
