Completion day gets all the attention, but the weeks immediately afterward are where a buyer’s ongoing legal and financial responsibilities actually begin.
Register the deed — this is not optional
The signed escritura needs to be registered at the Land Registry (Registro de la Propiedad) to formally record you as the owner on the public record. Until that registration is complete, your ownership is technically more exposed to a third-party claim, even though you hold the signed deed and the keys.
Tell the community of owners
Notifying the community administrator or owners’ association of the change of ownership is a standard, necessary step — otherwise community fee notices and votes continue going to the previous owner, creating confusion and potential arrears disputes.
Transfer the utilities
Electricity, water, and any internet or telephone contracts need to be transferred into the new owner’s name, generally by providing the utility company with the buyer’s details and the existing account or customer numbers from the seller.
The tax obligations that start immediately
IBI, the local property tax, becomes the new owner’s responsibility from the point of purchase, and non-resident owners additionally take on the annual non-resident tax return obligation from that point too — alongside community fees and standard property insurance.
Keep these documents together
A copy of the signed escritura, the nota simple from the Land Registry, the property’s energy performance certificate, its certificate of habitability where applicable, and the seller’s most recent IBI and community fee receipts should all be kept together — they come up repeatedly in future dealings with the property, from selling it eventually to routine administrative queries.

Frequently Asked Questions
What is the most urgent step right after completion?
Registering the signed deed at the Land Registry — until that happens, your ownership does not appear on the public record and is technically more exposed to a third-party claim.
Do I need to notify the community of owners myself?
Yes — informing the community administrator or owners’ association of the change of ownership is a standard post-completion step, since community fees and any related notices will otherwise still go to the previous owner.
What happens with utilities after completion?
Electricity, water, and any internet or phone contracts need to be formally transferred or set up in the new owner’s name, typically by sending the utility providers the buyer’s details and the relevant account/customer numbers.
Are there ongoing tax obligations that start right after completion?
Yes — IBI (the local property tax) and, for non-residents, the annual non-resident tax return, both become the new owner’s responsibility from the point of purchase, alongside community fees and standard property insurance.
What documents should I make sure I actually have after completion?
A copy of the signed escritura, the nota simple from the Land Registry, the property’s energy performance certificate, its certificate of habitability where applicable, and the most recent IBI and community fee receipts from the seller.
Utilities are one of the practical tasks this checklist should include — see our dedicated guide to transferring utilities after a Spanish property purchase.
IBI is one of the ongoing bills a new owner needs to understand — see our guide to who pays IBI in your first year of ownership.
