It doesn't matter if she need your support.
If you would support her she would qualify as dependent.

A printout could help.

Take a look at Chen C-200/02.
The child and eu citizen has also the right of unconditional stay for 3 month due to article 6 of the directive and therefore Chen is also applicable for a short stay.

IND can only refer to article 12 of the schengen border code.
http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=celex:32016R0399

Due to the schengen rules the passport holder has to prove in a other way if a exit stamp is missing.
A entry stamp from Thailand afterwards is a good proof.

Are you talking about a application for a Aufenthaltstitel "Familienangehöriger" in Austria.
If yes take a look here:

As far as I know only Ryanair want a passport for the check-in for a local flight inside the common travel area.

I think the question is if the wife can reach the international gate from a so to say domestic flight (Belfast) without passing the border control.
If yes there is nothing needed for a thai.

I guess the problem is to walk from a domestic flight to the international area.

At the bottom of the referred internet sites are links to the portal de immigracion.
There are simply orders in place in Spain.

Article 6 2004/38
1.1. Union citizens shall have the right of residence on the territory of another Member State for a period of up to three months without any conditions or any formalities other than the requirement to hold a valid identity card or passport.

2. The provisions of paragraph 1 shall also apply to family members in possession of a valid passport who are not nationals of a Member State, accompanying or joining the Union citizen

What are eea citizen and family member doing than? Right residing.
What is the ECJ talking in Metock section 99? Right residing.
Where is your understanding problem?

What is a eea national doing in a member state which is not his home country?

Metock is about the rights of non EEA national partners of EEA nationals who are residing in an EEA state other than that of which the EEA national is a citizen.

Metock C-127/8 section 99

The answer to the second question must therefore be that Article 3(1) of Directive 2004/38 must be interpreted as meaning that a national of a non-member country who is the spouse of a Union citizen residing in a Member State whose nationality he does not possess and who accompanies or joins that Union citizen benefits from the provisions of that directive, irrespective of when and where their marriage took place and of how the national of a non-member country entered the host Member State.

Read:

irrespective of how entered the host Member State.

To take advantage of Article 6, first you have to legally enter the country concerned!

Say who? Take a look at Metock  C-127/8.

A 5 year old would understand it if there is enough time to think about it. Your mother-in-law was not the onliest visa applicant.
I guess the papers weren't fully read and the dates at the application form were misunderstood.
Now the embassy could only cancel the visa and issue a new one with the correct data.

The normal way would be 23/06/17 in field 29 and 22/07/17 in field 30.
In field 24 two entries and 17 in field 25.
It looks like the embassy didn't understand the travel plan.
 

Which dates were written to field 29 and 30 at the schengen application form?

and be in Ireland illegally!

Simply not possible.
Do you see anything about a visa in article 6 right of residence for 3 month?

Article 5 right of entry section 2 sentence 3 
Member States shall grant such persons every facility to obtain the necessary visas.

How should that working for a entry visa for crossing the border if there is no border post?

EU directive 2004/38 Article 5 section 2 first sentence.

2. Family members who are not nationals of a Member State shall only be required to have an entry visa in accordance with Regulation (EC) No 539/2001 or, where appropriate, with national law.

If the irish law say no border control at the border to NI they waive a entry visa for family members.
The stay after crossing the border is covered from the eu directive article 6 anyway.

@jeab1980
Your travel was simply legal. Independently if your wife hold a UK tourist visa or not.

@jeab1980

The question is about Ireland and Ireland is not a Schengen member.
If there is no border control between NI and the south nobody can ask for a visa. The stay of a accompanying family member is directly covered from the eu directive.
 

As long as the brexit is not finalised you are still a eu citizen exercising your right of free movement in Ireland. The family member of a eu citizen need only a visa for crossing the border. If there is no border control there is no border control. It is a good idea to have the marriage certificate by hand in such circumstances.

Ask the embassy what they need for a Legalisation of a marriage certificate for the usage in spain. You need it later in Spain anyway.
http://www.exteriores.gob.es/Portal/en/ServiciosAlCiudadano/InformacionParaExtranjeros/Paginas/Legalizaciones.aspx

After you got it apply for a visa. I don't think they can turn down a marriage certificate which they legalised by their own.

What do you think the double tax agreements are good for?
