Arghh -just wrote loads and lost it!! So will summarise
Have kept BIL involved every step of way, he's had plenty of opportunity to say he wanted to use a solicitor or house clearance, he just doesn't care, he wants nothing from house.
I did it to help dh and out of respect for mil, who was a very private lady, and would've hated strangers going through her clothes jewellery etc.
Even if we'd used solicitor/house clearance still loads to do, there were 3 bureaus of paperwork and it took 2 days to find a death certificate - would anyone really pay £230 an hour for a solicitor to sort through this? Same with cleaning and disposal, someone has to get quotes make appointments, be at the property to let in etc. and insurance says we have to visit at least every 30 days to stay valid.
Not sure why anyway wouldn't maximise value of estate, I think it would be disrespectful to just get a man in a van to take the lot away.
It's not about the money it's about appreciating that someone has done more than their fair share, whether it was me or my dh. No one wants to clear their parents house, it's a very sad thing to do, but sometimes you have to put others (in this case late MILs) needs above your own and do the right thing.
And what do I intend to do? Nothing of course, I really just wanted a rant which I can't do in real life because it could cause bad feeling, I don't feel entitled to the money, it just galls me that it's going in a spreadsheet and taken for granted like all the rest. A thank you would be perfectly fine!
