The Other Parent's Signature: The Document That Stops a Move

Last updated: 10 September 2026 · by Khris Rueda, Founder of Spainlander

Key takeaways

  • The other parent's notarised authorisation surfaces late, when an authority moves from considering to processing.
  • Whether it is required depends on your custody order, the country that issued it, and which body is asking.
  • Ask the consulate, the school and your own lawyer before you file, and get the answers in writing.
  • Issued abroad it usually needs an apostille and a sworn translation, each with its own queue.

Is your landing date realistic?

Most families move to Valencia three months later than they planned, because they find out about the school calendar too late. Five questions, thirty seconds, and you will know whether your date works.

# The Other Parent's Signature: The Document That Stops a Move Most relocation writing assumes two parents moving together. A large share of the families who write to us are not that. Separated. Divorced. Widowed. One parent doing every piece of the paperwork while the other is somewhere between fully involved and entirely absent. And at some point in that process — rarely at the beginning — someone asks for a document that only the other parent can provide. ## Where it appears, and why it is always late It does not appear on the first checklist. That is the whole problem. It surfaces when an authority moves from *considering* your application to *processing* it: a consulate reviewing a visa file for a minor, a school registrar completing an enrolment, a town hall registering a child at an address. Each of those is a different body with its own rules, and none of them tells you in advance that the others will ask too. By then the flights are often booked and the school year has a date on it. **This is a document with a lead time, held by a person you may not control.** Those two facts together are what turn it from an errand into a wall. ## Who decides, and it is not us We are not lawyers and this page does not tell you whether your situation requires the other parent's consent. That question turns on your custody arrangement, the country that issued it, and the specific authority asking — and the answer genuinely differs between a Spanish consulate abroad, a school and a registry office. What we can tell you is that **the question exists**, that it arrives late, and that the families it stops are the ones who met it for the first time in month eight. ## What to establish early Not answers. Questions, asked while there is still room to act on them. **Ask your own lawyer, in the country where custody was decided:** does relocating the children abroad require the other parent's consent, and is your existing order silent, permissive or restrictive on it? A court order that does not mention international relocation is not the same as one that permits it. **Ask the consulate handling your visa** — before you file — what they require for a minor when only one parent applies. Ask for it in writing. **Ask the school**, when they answer, what they need from a parent who is not on the application. Registrars answer this quickly, because they meet it often. **And find out the mechanics where the other parent lives.** A notarised signature is a physical appointment somewhere. If it needs an apostille, that is a second process on top, with its own queue. ## What tends to be needed, when it is needed Where a notarised authorisation is required, it usually has to name specifics rather than grant a general permission: the children, the destination country, and the purpose. A signature from years ago on a different matter will not carry it. If the document is issued outside Spain, it will generally need to be **apostilled**, and where it is not in Spanish, translated by a sworn translator on the Spanish foreign ministry's list. Both take time and neither can be started until the signature exists. ## Why we wrote this Because a family wrote to us with the visa approved, the school confirmed and the flights booked, and the only thing standing between them and September was a signature in another country. **The paperwork you cannot do yourself is the paperwork to start first.** Everything else on your list moves at the speed you decide. This one moves at the speed of somebody else's diary.
