If you have assets in Spain it is advisable to have a Spanish will. If you do not have a will and if you have no relatives, your assets will revert to the British Government. If you do have relatives, the absence of a Spanish will incurs delay and extra cost, which can be avoided if you have a Spanish will.
To save time and money and ensure your assets are left to a relative, friend or charity, the easiest way to achieve this is by signing a Spanish will.
