The shared foundation:
Hague apostilles
Both Spain and Mexico are Hague Apostille Convention members, so U.S. public documents need an apostille — not consular legalization — to be legally valid there. The apostille comes from the authority competent for your specific document: the issuing state's Secretary of State for state documents (birth, marriage, death certificates, notarized documents, court records), and the U.S. Department of State for federal documents — of which the FBI background check is by far the most common.
Two universal traps before we split by country. First, signature verifiability: vital records must be recently issued certified copies whose signing official the state can verify. Second, sequencing: the apostille happens first, the translation second, because your destination will want the apostille certificate itself translated. Translate first and you'll pay for a second translation later.
Spain: recency rules and
the traductor jurado question
Spain's paperwork culture prizes freshness: for many procedures — marriage registration, nationality files, some visa categories — Spanish authorities expect civil documents issued within roughly three to six months. Order fresh certified copies before apostilling; an apostilled 2015 birth certificate is often a rejected 2015 birth certificate.
The documents Spain most commonly wants from U.S. residents: FBI background checks (federal apostille) for non-lucrative, student, and digital nomad visas; birth and marriage certificates (state apostille) for family reunification, marriage, and nationality; and academic credentials for homologación of degrees. The translation nuance: for procedures inside Spain, authorities generally require a traductor jurado — a translator sworn before Spain's Ministry of Foreign Affairs. For several consular procedures in the U.S., certified translations are accepted. This distinction is worth real money: buy the jurado translation when your procedure demands it, not before. We tell clients honestly which their specific process needs.
Mexico: dual citizenship,
property, and the perito rule
Mexico's flows from the U.S. are the busiest in the hemisphere: apostilled U.S. birth certificates for registering dual nationality for U.S.-born children of Mexican parents; powers of attorney for buying and selling property; school records for relocating families; and death or marriage certificates for inheritance matters. State documents get their state's apostille; the translation into Spanish must cover the apostille page — Mexican registries and notaries check.
Mexico's translation nuance parallels Spain's: many authorities accept professionally certified translations, but some Mexican states and notarías require a perito traductor autorizado — a translator authorized by that state's judiciary. Which rule applies depends on the receiving office, not on general principle. Before paying anyone, confirm with your registro civil or notaría — or send us their checklist and we'll read it with you, free, and route the translation accordingly.
Worked examples,
start to finish
Registering a Texas-born child as a Mexican national: order a fresh certified copy from Texas Vital Statistics; Texas SOS apostille in Austin; certified Spanish translation of certificate plus apostille; present per your consulate's or registro's checklist. Typical timeline: two to four weeks, mostly apostille processing.
Moving to Spain on a non-lucrative visa: request your FBI check (fast, digital); federal apostille at the U.S. Department of State — the step people mistakenly try at their state's SOS; state apostilles for marriage/birth certificates; translations per your consulate's rules (several accept certified; Spain-side steps want jurado). Recency windows run from the FBI check's issue date, so sequence tightly against your consulate appointment.
Both examples compress into one order at Selládo: we pre-check signatures, run the correct apostille chain (state or federal), and produce the translation your destination actually accepts — from $99 per document plus translation. One WhatsApp message, one quote, one finished packet.
Timelines you can
actually plan around
Work backwards from your fixed date — the consular appointment, the wedding, the registro civil visit. Ordering fresh certified copies: a few days to two weeks depending on the state and shipping. FBI background check: often days, since results are digital. State apostilles: from same-day counters to several weeks by mail, varying by state and season. The federal apostille for FBI checks at the U.S. Department of State: consistently the longest single step by mail — plan for weeks, not days, unless you use expedited channels. Translation: 24 hours at Selládo, deliberately never the bottleneck. Then add international shipping if originals must travel.
Now layer the recency rules on top, because they run in the opposite direction: Spain's three-to-six-month windows mean you can't start too early either. The optimal sequence for a Spanish visa: request the FBI check first (its clock is usually the tightest), order state certificates in the same week, submit apostilles immediately upon receipt, translate the same week apostilles return, and book the consular appointment for the middle of your validity windows — not the end. For Mexico, recency pressure is lower, but consulate appointment availability becomes the scarce resource; have the packet finished before hunting for the slot.
Build in one failure's worth of slack — a bounced apostille or a lost envelope costs two to four weeks. Padding you didn't need is a pleasant surprise; padding you needed and didn't have is a rebooked consular appointment three months out.
