Quick answer
Recognition, enforcement, and modification are different questions. The issuing court’s authority and the procedure used can matter.
Do now
Obtain certified complete orders, proof of service, and translations if needed. Identify which part you want recognized or enforced: marital status, property, support, or parenting. Seek advice before remarrying or transferring property based on an uncertain decree.
Watch for
A foreign decree does not automatically resolve all US support, tax, immigration, or property issues.
