I purchased a house in Taipei 5 years ago, and the house deed (建物所有權狀 and 士地所有權狀) are tied to my ARC on the certificates.
However, I am leaving my job (and Taiwan) next month, which means I need to relinquish and cancel my ARC when I leave, and return it to the government office.
Once I don’t have my ARC anymore and it is canceled, how do I prove ownership of my house?
Do you know where I can locate my ID number? I thought my ARC number was my ID number? What if I want to sell the house while I am not a resident (and thus without an ARC)?
Above your name the ARC displays the UI No. (what is usually referred to ID number), that stays unchanged through out time (with some exceptions). In the Image UI No. A900000016
Not sure how it can affect this situation. But if the arc is old format, and then get a new one later the ID number will be changed to the new format. The back of the née arc will have the old number, but maybe worth some thought.
As an aside, are you planning to sell the house? You can just do the online form saying you are leaving for a year or more which buys you time to sell. Returning the arc like that seems like cutting your own throat. Let it run out naturally.
Thankfully my ARC is in the new format. I may sell the house eventually. Which online form are you referring to that allows you to state you are leaving for a year?
If I get Taiwan citizenship one day, would this also become my citizen ID number? When someone converts an ARC to citizenship, does their ID number remain the same?
