We are a same-sex couple with adopted sons who now share our surnames and have new passports to reflect this. Does anyone know if, when travelling with our sons to other countries where adoption by same-sex couples is legal, we can just take the passport (similar to a straight couple with their adopted son) or if we must also take the adoption certificate? I know some people might take the adoption certificate when travelling just in case, but we were wondering if taking the passport is sufficient (we don’t really feel like carrying unnecessary paperwork whenever we decide to travel - we do keep digital copies in our phones though).
Many thanks
