I'd rather not post my name here in case someone I know in RL should recognise me but hope I won't be considered a troll.
There's a bit of history here.
My dh's parents have had a business for a number of years - they are really terrible at what they do and have cut corners (illegally in many cases) not paid people and generally were in such bad shape a couple of years ago that they were on the brink of everything collapsing around them, it didn't help that MIL was conned, rather equisitely to the tune of about 150 thousand pounds!
Just over a year ago my dh decided enough was enough and that he was going to help them out, sort out the business, strip the rot and get them making some kind of profit. he wasn't going to do it for free either (it's important to mention this for later) So for the last year dh has been working for at least 90 hours a week (he also has a really busy FT job) he hasn't had any time to spend with us except for four hours on a Sunday. We've seriously gone without and we have remortgaged our house and ploughed 60 thousand pounds back into their business.
I came up with a suggestion which dh went with (his parents have given him full control of the business now)and it looks like a deal is pretty much on the table and they have been offered a huge amount by a VC to buy the business completely. As they were likely to be left with nothing a few years ago my PIL said to dh and I that if we made any money from helping them that we would be entitled to half of all profits.
The problem now is dh's brother - who turned the other cheek when we asked if he could contribute initially with time or money to help- wants to have a share and is asking for a third of the money for doing absolutely nothing. Whilst we've all gone without and my children haven't had holidays, treats or their dad for a while he has enjoyed his lifestyle without a care in the world.
I am being a money grabbing cow? The brother stands to inherit the pil's house BTW - he won't be left skint in any way.
I feel bitter as the brother only ever bothers to see his mum if he wants favours (usually money)and now he is trying to put a claim on this money we look certain to have in a few months.
