Is a marriage in Thailand valid in Malaysia?

It can be recognised and registered in Malaysia if the contract is valid under Syariah law and the registration procedure is followed, but a Thai certificate alone is not enough. The religious marriage certificate from the Provincial Islamic Committee is only proof of the contract, not Malaysian permission for polygyny. The certificate is usually endorsed at the Consulate General of Malaysia in Songkhla (or the Embassy in Bangkok), then registered at the Islamic religious affairs office of the state of residence within six months (Act 303 s.31; equivalent state Enactments). The religious affairs office or Syariah Court will check the wali, the witnesses, the accredited officiant and the status of the parties. If the wali is in doubt, the court may refuse to confirm the contract and the couple may need to renew the contract. If it is polygyny without permission, the husband is usually charged and fined first. See Thailand and recognition of marriages abroad.
