lunavix - my mum died recently without a will. Go and see and solicitor and see what they say. How complicated it all is depends on teh size of teh estate (ie if inheritance tax comes into it) and number of differnt accounts/policies etc. Have a look on teh probate website - they have list of things that need to be done.
Contact companies straightaway to tell them. Contact everyone. Most companies aren't too bad but some are useless. Don't forget pensions as well.
Hi Lunavix.............I am a probate solicitor. I know we are expensive but if you need a solicitor's help then I will do a discount for mumsnetters. Reply to this and I will let you have some contact details.
