Hi leeneia, sorry to hear your sad news, the first thing to do is contact a funeral director/undertaker, there will be a list in the local phone book or the hospital might have a list available. Ask them how much it will be for the type of service you want, burial or cremation, as the prices vary, it is worth getting a few , ie at least 2 quotes.If he was a churchgoer, you will nedd to liase with his priest/vicar or rabbi whatever to arrange the service, you will need to inform friends and relatives etc of his death, so they can arrange to go to the funeral. Contact the insurance companys involved to claim any monies owed, to do this you will need copys of the death certificate, get a few copies, as you will need them for transferring bank accounts/ stocks & shares etc.Also contact his previous employers to see if his wife can claim any pension etc.
I am not sure of the situation in the US , but there might be a volounteer group at the hospital, the Red Cross, or similar, wich may be able to offer practical help/support if you need it.All the best, if you have any specific questions, then post here again, I am sure somebody here will be able to give you some good advice.take care.john
