Money in an unused Spanish bank account does not automatically pass to the state. The law sets a 20-year period without action by the owner and requires advance notice, with an exception when the cost of notice exceeds the balance.
In Spain, money in a bank account may be declared abandoned and transferred to the state if the owner takes no action to exercise ownership rights for 20 years. The process is set out in Article 18 of Law 33/2003 on the Assets of Public Administrations. Funds are not taken after an ordinary period without transactions: the statutory period must first elapse, followed by a formal process.
The Bank of Spain says the bank must notify the account holder at least three months before the 20-year period ends. If the holder has died, the bank must contact the heirs using the latest address on record. The notice is not required if its expected cost exceeds the amount in the account.
If nobody claims the funds after notice, the balance is transferred to the public treasury. The Bank of Spain says the money is used for public purposes, including education and accessibility programs for people with disabilities.
An account holder can prevent the process by carrying out a genuine transaction, such as a transfer, deposit or withdrawal. Bank fees alone do not count as activity initiated by the owner. The source also advises customers to keep contact details current and make sure the account has no unpaid obligations.
