Sums it up really.
I'm not sure you expect to see your siblings much going forward anyway so nothing to lose.
I think using a solicitor sounds a good idea if it'll reduce any comeback. Don't forget to charge everything you can think of since your dad died into his estate as you are entitled to full expenses for all the clearing of the bungalow etc, you might have owned half, but your dad occupied it so clearing it is the cost of his estate.
I think you have 2 daughters so presumably you're family will get 3/7 as well which is good (and maybe give your daughters a house deposit?)
I certainly don’t expect to see anything of my brother but my sister might still stay in touch - as long as I don’t need any help in a crisis!!
So I suppose I should look out for our own interests .
As I’ve almost finished probate - just the house sale to go through now - would it be possible to hand it over to the solicitor to check and sign it off?
