So sorry to hear of your loss. Its tough to lose a mum. We made a will few months ago and we did not get a copy of it... its with our solicitor so your mums will be too. I am not an expert but definitely make an appointment with your solicitor first before you do anything with your late mums things. Solicitor will be able to advise you on all you need to do to sort your mums affairs they will have been through that so many times with other clients. I presume you will need the death cert to take with you also. Ref credit union.......I worked in a credit union for short while few years ago and I learned at the time that they have insurance on their customers and when an account holder dies there will be a sum of money due from that insurance. It may only be a thousand or something but people found it helped with costs of funeral etc at a sad time. The executor or executors will have been specified by your mum on her will. I know with ours we had to put down details of all accounts, insurance policies, pensions etc so that if anything happened to one or both of us God forbid all of the information was there for next of kin. I would suggest both of you go to the solicitor together and do these final jobs together for your late mum. Ye will be in a quandry for the next few weeks its tough process to sort out a family members affairs but it has to be done even when your grieving. All will become clear as ye go along bit by bit.
