Would I be going to a family law firm for that?

My husband has accrued an amount of credit card debt I'm concerned about, and we have agreed to make a postnuptial agreement that treats our accounts (whether asset or debt) as separate (except for our one joint savings account). This should be pretty straightforward. We both waive our right to spousal support as well and don't have kids or business assets to protect (it would just be my brokerage account and our IRA's treated as separate really).

If we're making the post nuptial agreement, I thought it would be smart to also make a will since we don't have one in place.

Is there a way I can one-stop-shop these endeavors?
