Remarriage - Same spouse


I have divorced my ex-Huss and who is a Taiwanese citizen years ago and things worked out so we are thinking of remarrying each other.

We got married and divorced in Taiwan. Our marriage was registered in my home country but the divorce has not yet been registered there.

Does any one know how would be the process to remarry? Would I still need the standard documents from my home country such as single certificate and so. I am thinking if it is to marry the same person and the divorce has not been registered in my country yet, can it just be annulled here? Because I can’t apply for a single certificate since I am still married back home. Thanks in advance for any input.
