Can you cash any check of a deceased person into your spouses bank?

Generally, you cannot cash a check made out to a deceased person, even if you are their spouse. The funds belong to the deceased's estate, and cashing the check could be considered fraudulent. Typically, the estate must go through probate, and any checks owed to the deceased should be deposited into the estate account. It's best to consult with an attorney or the bank for specific guidance.
