Crypto inheritance, Spanish tax and Form 721, DAC8, fraud cases and cold-storage custody. A practising Spanish lawyer who knows the crypto world first-hand – and advises you in English.

Each service can be booked on its own or as part of a full plan.
A will with a crypto clause, a wallet inventory and an access protocol for your heirs that does not compromise your security today.
Gains and losses, swaps and staking, Form 721, replies to the tax office and voluntary disclosure of past years.
We help you set up and verify your cold storage. You generate and keep your seed phrase – we never see or touch it.
Criminal complaint, on-chain evidence preservation and urgent requests to exchanges. Beware of fake “recovery” firms.

All guidesIn Spain a gain or loss arises when you dispose of crypto: selling for euros or swapping for another coin. Simply holding is not taxed as income, but it can trigger reporting duties such as Form 721 and, depending on your wealth, wealth tax.
Yes. According to the Spanish Directorate General of Taxes, a crypto-to-crypto swap produces a gain or loss that must be declared.
It forms part of your estate like any other asset. The problem is practical: if nobody knows the keys or platforms, it may be inaccessible forever. With exchanges, heirs must prove their status with probate documents.
Never. We help you set up and verify your custody, but you generate and keep the seed yourself. We put this in writing.
Our focus is Spanish law. Where another country is involved, we coordinate with advisers there when needed.
Keep all evidence, never pay upfront fees to anyone promising to “recover” your funds, and get in touch quickly: time is key to try to freeze funds at exchanges.
Tell me briefly about your situation. You will receive a clear proposal within 24 business hours.
