<prompt> Human: My dad has been drinking heavily the past 6 months. His way of coping with my mothers mental illness. Yesterday he had a heart attack and now he has passed. I have no clue what to do. Ive barely spoken to either of them the past 5 years. Does it matter hes my step dad and we dont share the same last name? My mother can not take care of the house or herself, she also cant drive. I just dont know what to do or where to begin. I would appreciate any help. Im still at the hospital as im typing this. I dont believe there is a will either.Edit:1. We live in California, i live close enough to her to help. But i will not be moving in or have her move in with me.2. A social worker did not talk to us at hospital before we left, i suppose i will call back Monday morning and get assistance.3. Since its the holiday weekend everything is closed. But ive talked to a funeral home and they will be picking up my father Tuesday morning and cremating him for around 800.4. My mother has kaiser and has not seen a doctor in over a year. I plan on taking her asap next week. I also believe she gets state disability already. She is also not objecting of me taking over the bills and finances.5. I also will be seeing a probate lawyer next week as soon as i can. Their bills seem to be in order, everything is payed for the this month like mortgage, insurances, water and pge. All the vehicles and motorcycles are payed off also. I want to thank everything for the help and kind wishes. It has helped out tremendously. If you feel im missing anything still, im all ears. I hope everyone has a great Holiday.  <response>: Follow the advice people are giving you regarding seeking help from social services to get care for your mom. If your stepdad has no other children or previous wives, you will probably be considered the executor of his estate whenif your mom is ruled incapable of handling it herself.I just wanted to mention something in regards to the funeral. If no one objects and if money is an issue, you do not have to have an elaborate funeral at a funeral home. Most services like that cost thousands of dollars. My friends dad was cremated prices vary by state and area but here was several hundred dollars with his ashes returned in a free plastic box, a vase was purchased for under 50 at a chain home decorating store to transfer his ashes into, a service was done with a donation to the church 100 or so, and then he was buried in a pre-purchased plot--the groundskeeper just needed a shovel to dig a hole deep enough for the vase so they didnt have to pay for a full excavation. However, the ashes do not need to be buried if your stepdad didnt make this purchase. My wife kept her dads ashes in their plastic box and spread them in various wilderness locations which were his favorites so his estate only had to pay for the cremation cost Social Security pays 250 death benefit.We are terribly sorry for your loss and hope things proceed as smoothly as possible for you and your mom.
