It is generally a good idea to make a will for any assets that you own, including properties and assets in Spain. A will allows you to specify how you want your assets to be distributed after your death and can help to avoid disputes among your heirs.

Making a will can be especially important if you own property in Spain, as the laws of succession for property ownership can vary depending on the region where the property is located. By making a will, you can ensure that your property is distributed according to your wishes.

It is also worth noting that if you do not have a will and you own property in Spain, your property may be subject to forced heirship rules, which dictate how your property must be distributed among your heirs. Forced heirship rules can be complex and may not align with your wishes for the distribution of your property. By making a will, you can ensure that your property is distributed according to your wishes and avoid any potential disputes among your heirs.

If you would like to make a will for your Spanish properties and assets, it is recommended that you consult with a lawyer who is familiar with Spanish inheritance laws to ensure that your will is properly prepared and legally valid.
