Well for the USA that is considered a damaged passport, even if it is a little bit. It is no longer valid. And because it is damaged it does not qualify as proof of who you are. You have to turn the passport in and now provide even more documentation of who you are.
This happened to me and it was a pain as im a dual citizen with canada so i had to provide my birth abroad certificate from 1986 and signed affidavits from my sibilings and father stating i am.who i am.
Normally when you exchange to a new passport they use the old one as proof, but with damaged its a no go unfortunetly. :( again this is for american passport
i dont like to stereotype, but from over 25 years of living in thailand and being married to a thai person, that their emotions are like glass...once you break that glass there is no putting it back.
In my relationships that have ended with certain thai people, i have found they greatly appreciate it when you walk away from the relationship without upset. That they will appreciate more and respect you more if you dont fight and make drama about it.
She can only go to court and divorce you without you being there if she can proove that she hasnt seen or heard from you in a certain amount of time.
If she wants a divorce, just divorce here. "Reasoning" isn't a culture thing in Thailand. Once Thai ppl are done with you, they are done with you.
Just so you know if you arent in the same house at the moment be prepared that she can come in and take anything she likes from you as you are still married.
Quickly get that divorce to protect your assets.
Happy Divorce my friend...dont stick around someone who doesnt want you...like i said...when thai ppl are done they are done, they hardly ever change their minds or come back to you.
