Advice needed

My yearly extension based on Marriage expires on the 29th Nov 2021, I am aware that 400,000 baht needs to be seasoned 2 months prior to that extension expiry date, I was planning to return to the UK around September time and Not return until mid Nov 2021,  can I still apply for my extension even though I plan to return to Thailand a couple of weeks before the extension expires. Is it that allowed ? Or do I physically have to be in Thailand a full 2 months before my Nov 29 expiry date. 
 

Many thanks

You can leave and re-enter using a re-entry permit during the 2 months before for the 400k baht in the bank requirement.

Pay attention to the the quarantine requirements when you plan on returning to insure you are out of quarantine before your extension expires.

Many thanks
