Credit card debt from deceased mom

PA> Is my father responsible for debt my mom ran up on credit cards? He is not on the statements anywhere nor is he an authorized user. She passed away on June 1st.

see info below from wld site:


Whether you are married or single, you alone are normally responsible for paying off the debt. The account will appear only on your credit report, and may in limited cases appear on the credit report of any "authorized" user. However, if you live or have lived in a community property state (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, or Wisconsin), you and your spouse in some cases may be responsible for debts incurred during the marriage, and the individual debts of one spouse may appear on the credit report of the other.
