Kor ror 22 is family registration in Thailand, First you need to prove the married certificate is true by the Embassy then translate in thai language and prove the right translate at Ministry of Foreign affairs at Changwattana then can brings that paper to any District office in Bangkok or any provinces in Thailand to get kor ror 22 before go get call and asks first some place as my home need to bring 2 witnesses and from my experience I waited for my Finnish embassy 1 and half months to get stamps so good luck 👍
