as I read through this thread there are two sets of conflicting advice when a couple marries during the year - each making contributions to an HSA prior to the marriage within the tax year.
What is missing from the 'accepted solution' is this tip on the left side of Page 4 of the intructions to Form 8889:
"If you had family coverage on the first day of the last month, you do not need to use the worksheet; enter $7,200 on line 3."
The 'accepted solution' attempts to use the worksheet when the Tip states you are not do so if you had family coverage in December, which is the case in the original OP question.
What this means is @Mike9241's approach is supportable by the Form 8889 instructions. The limit for the family is $7200 (plus an extra $1000 for each parent who is over 55 years old).
