Eliza - far too little, far too late absolutely. They could have called this week, the could have made sure the minister talked to DS, they could have got the one fact they did include right... grrrr
You are really so nice & patient with them, very forgiving.
It is really, really sad that a young bloke died, his brother, father and mother etc were there and his son was the only one who cried... very sad :(
I absolutely agree with maryz about the legal stuff - I think you should get onto it tomorrow if you haven't already.
I would start by ringing any of the legal firms he may have used and tell them what you need to know (who is holding the will) and they will tell you how to find out.
I would also call his Grandmother up and ask her when DS can go and collect some things from the house.
Your DS is also entitled to know exactly how his Dad died - so let them know you want copies of the autopsy/Drs notes. He will want these details when he grows up, even if he doesn't now.
