This topic isn't too stale for me to add: I have processed marker changes in Missouri pre-op for Passport, Social Security and Drivers License, in that order using the new passport as proof of birth. I am scheduled to have a little work done next year, so I'll take care of the birth certificate then. I do not have any type of court order to make the gender changes that went through, just my explicit letter of treatment from my primary physician. My doctor's letter was prepped in accordance with the NCTE model letter.( Sorry no links from newbs, see paste below)
It should also be noted that the MO-DMV is under recent orders not to retain records. In short after scrutinizing my letter, they made the changes in the computer and I'm on my way with no further record in their system. This is good rather than a file stuffed with judgements, records and such.
There could be utility in having mismatched documents depending on a particular individual circumstances, though that's not for me.
It has been my assumption the a court order will be required to update my BC pre or post-op. Though I will inquire if the division of vital records will work with a surgical record, combined with my doctors original letter.
Paste:
I, (physician's full name), (physician's medical license or certificate number), (issuing State of medical license/
certificate), (DEA Registration number), am the attending physician of (name of patient), with whom
I have a doctor/patient relationship. (The letter must indicate that the physician is either an internist, endocrinologist,
gynecologist, urologist or psychiatrist.)
(Name of patient) has had appropriate clinical treatment for gender transition to the new gender (specify
new gender male or female).
I declare under penalty of perjury under the laws of the United States that the forgoing is true and correct.
