(Passports • Consent Letters • Travel Requirements)

Everything is booked.

“Do you have a notarized consent letter?”

Traveling Internationally with Children This Summer? Read This Before You Go
International travel with children comes with extra requirements.

That’s usually the moment parents realize…international travel with children comes with extra requirements.

And missing just one document can delay or stop your trip entirely.


What Documents Kids Need to Travel Internationally.

Before you head to the airport, here’s the baseline:


For minors traveling internationally:

  • Valid passport (required)

  • Visa (if required by destination country)

  • Travel consent letter (in certain situations)

  • Supporting documents (depending on family structure)


Unlike domestic travel, a birth certificate alone is NOT enough for international trips.

According to the U.S. Department of State, all children — including infants — must have a valid passport to travel internationally. https://travel.state.gov/content/travel/en/passports/need-passport/under-16.html


When You Need a Consent Letter

This is where most families get caught off guard.


You typically need a consent letter if:

  • One parent is traveling alone with the child

  • The child is traveling with grandparents or relatives

  • The child is traveling with a group or school

  • One parent is not present at the airport


Even if it’s not always “required” by law,it is strongly recommended and often requested.


According to U.S. Customs and Border Protection, a notarized letter of consent is recommended when a child is traveling with one parent or someone who is not a parent or legal guardian.


Why This Matters More Than You Think

This isn’t just paperwork, it’s about safety and compliance.


Airlines and border agents are looking for:

  • Proof the child is traveling with permission

  • Protection against international custody disputes

  • Clear documentation of guardianship


If something looks unclear, they can:

  • Delay your travel

  • Ask additional questions

  • Deny boarding or entry


The U.S. Department of State also recommends carrying documentation showing the child’s relationship to accompanying adults.


What Should Be in a Consent Letter

A proper consent letter should include:


  • Child’s full name and date of birth

  • Travel dates and destination

  • Name(s) of accompanying adult(s)

  • Contact information for non-traveling parent(s)

  • Emergency contact details

  • Signature of parent(s) not traveling


And ideally: It should be notarized

Notarization helps confirm the identity of the signing parent and adds credibility to the document if questioned during travel.


When You May Need More Than a Consent Letter

Depending on your situation, you may also need:


  • Birth certificates

  • Custody agreements

  • Court orders

  • Death certificates (if one parent is deceased)


Especially when:

  • Last names differ

  • One parent has sole custody

  • You’re traveling internationally for extended periods


Requirements can vary by country, so always check your destination’s entry rules in advance.


Where Families Run Into Problems

Most travel issues happen because:


  • Consent letters are missing

  • Documents are incomplete

  • Names don’t match across documents

  • Letters are not notarized

  • Parents assume “we’ve traveled before, we’re fine”


Rules are being enforced more consistently now not less.

Traveling Internationally with Children


Where Notary Services Come In

This is one of the most common things we help with, especially in the summer.


We do NOT:

  • Give legal advice

  • Determine custody requirements


We DO:

  • Notarize travel consent letters

  • Verify identity of signing parent(s)

  • Help ensure documents are properly executed

  • Provide guidance on what information is typically included


A properly notarized document can help avoid unnecessary delays at the airport.


What About Apostille?

Most vacations won’t require this but some situations might.

You may need an apostille if:


  • The child will be staying abroad long-term

  • Documents are being used for school enrollment

  • Legal or residency processes are involved


Apostille certifies your document for use in another country (Hague Convention countries). https://travel.state.gov/content/travel/en/records-and-authentications/authenticate-your-document/apostille-requirements.html
