I have a non imm-O visa that I extend every December (due to marriage).  If I leave the country after extending and come back 8 months later before my next extension is my stay still valid?  Or is there some expiry if I stay out of the country for a certain number of days and I have to apply for a new visa?

 

Thanks

It will still be valid as long as you buy a re-entry permit (1,000 THB) on the way out at the airport to protect the stay. You can also buy  are-entry permit anytime at your local immigration office. You can stay out as long as you like, but need to return before the re-entry permit expires (same date as your extension) if you want to renew the extension.

In order to keep your extension of stay period alive you must get a re-entry permit before you leave Thailand.

Have you ever bother to notice the date on your extension stamp? Should not that have a stamp telling you how long you can stay? It will expire as soon as you leave the country unless you've an reentry permit. A reentry permit does not extend your permission to stay date. It just preserves that date (for entry) which you should find out from you extension stamp on the passport.
