HSA contribution limits for both spouses

[cheapass]

I met with a CFP from Fidelity today and we were going over our retirement plans. One thing he pointed out is that my wife and I collectively are on track to contribute $10,150 toward our HSA's ($6,750 for mine because I insure our daughter, and $3,400 for hers). He said I should check into this because the IRS may say the "family limit" is $6,750 collectively and that we cannot contribute any more than that.

Anyone researched this?

Not "may say" - the IRS does say your combined limit is $6,750.  See 2016 Publication 969 - p969.pdf.  One excerpt below.

Rules for married people.
If either spouse has fam-
ily HDHP coverage, both spouses are treated as having
family HDHP coverage. If each spouse has family cover-
age under a separate plan, the contribution limit for 2016
is $6,750.

Shit. Thanks. Well I guess the good news is we can just adjust our contributions for the remainder of the year and not worry about going over.

This is the first year we've both had HSA's. How does it work for withdrawing funds, can she use her funds for my expenses and vice versa even though we're on separate insurance plans?

Yes.

As IRS publications go, 969 is reasonably comprehensible.  Probably worth reading the part about HSAs.
