the HSA must be in the name of only one individual - you or your spouse. you and your spouse can each have their own account.
for a married couple, if either spouse has family coverage (the insurance covers them and their spouse and/or a dependent. the plan's deductible meets the minimum IRS requirement for a family deductible and doesn't exceed the maximum for a family deductible) both spouses are treated as having family coverage. For a family the maximum HSA contribution must be split equally unless they agree to a different split. in your case that means you can make the family maximum contribution to just your account. it can be used to pay any qualified medical expense, except health insurance premiums, for any member of the family. in this case only one 8889 would be filed.
it is also permissible, in your situation, for your spouse to have an HSA. in this case the total contributions to each of your accounts can not exceed the family maximum. the spouse's account just like yours can be used to pay any qualified medical expense , except health insurance premiums, for any member of the family. A second 8889 for the spouse would need to be filed
In your situation if your are filing a joint return, then only one account is really needed. The reasons H & S each having an HSA is when they're filing separate returns., have different employers (one could carry self-only coverage while the other had family coverage, and other situations.
