Let's simplify this.
If you where married OUTSIDE Thailand, then yes, you need to get your marriage legalized through your embassy and then MfA in Thailand before you can go to ampheur and get a khor ror 22, because it doesn't apply to marriage done inside Thailand.
If you married INSIDE Thailand, you will never need, and can never get, a khor ror 22.
On the other hand, if you married OUTSIDE Thailand, you cannot get a khor ror 2, because you need a khor ror 22 for marriage registration from abroad.
But lets assume that the marriage was done INSIDE Thailand.
In that case all you need is for your Thai spouse go to the ampheur with their ID card to obtain a khor ror 2, which is the regular marriage registration document for marriage INSIDE Thailand. Cost is 20 baht. No need to legalize at an embassy or MfA for use inside Thailand.
The original rose border marriage certificate you got when you got married INSIDE Thailand is a khor ror 3.
I do this every year for 8 years in a row now.
If you married inside Thailand you need a khor ror 2. 22 is not for you then.
