Inheritance going to 1 adult sibling

I think you have a good handle on it TBH. It's unfair and will likely cause a rift with your brother. But it's your parents' right to choose. Playing favourites with children is a bad idea at any stage of life (even after the end of life in Wills) and I wonder if this is a continuation of behaviour by your parents over many years, meaning preference by them for their youngest child.

This sounds extremely messy. Your parents money is Thetis to do with as they wish. However, as PPs have said these arrangements can be fraught.
Your parents would be much better off moving your brother in with them and then he can pay off the debt by eg selling his house/ not paying rent. If they sell their house and give him the money then they have nothing ... what if your brother kicks them out

General consensus inheritance is not a right.

However you as a family need to all sit down and address the fact that homes are regularly sold to finance care at later stages of life, so what is their plan. E.g. should they talk to a financial advisor and put a lump sum in to stocks/shares, or will they not being pay rent and board at your brothers in which case they will save their pensions? Also have they arranged and paid for their funerals?

If you really want to make your point I'd message your whole family on whatsapp Inc SIL and say you think it's wonderful that your brother and SIL will be living in a multi generational home creating strong bonds between GC and GP and the relief in knowing your parents on going care will be managed by your brother and sil and of course when the time comes you will help with things like lifts to appointments (basically nothing financial)

Chances are the majority of this will all fall to your SIL who will have 3 kids and 2 parents plus possibly her own to care for for the next 20years.

It will either then be accepted or oh no hang on type of situation

It's a messy, hurtful situation.

I think I'd try and view it as a lucky escape. Your parents are now your sibling's problem to support.

My DP have helped bail out both my siblings - one did keep having money issues but has finally stabilised a bit - other it wasn't so much their fault messy breakup but with first child they got free childcare and frankly all the attention on that GC.

When we got into trouble - house and redundancy we got a loan we paid back with some interest very welcome intervention but not on the same level as siblings but was a huge help.

I've had moments of envy/resentment - especially when things like serious accidents happened and we were on our own at same realising DP felt they had little choice in the matter as siblings were in serious trouble.

I also worried as feared care expectations were being directed at me by IL and DPs - but we move considerable distance for work - and now DPs need help siblings have stepped up (to my surprise) - though they snip at each other for not doing more as suspect they do at me as well having doubtless forgotten all the bail outs and help they had years before though main factor limiting my help is distance.

All I can suggest is that you strongly suggest to your DP that they get legal advice to protect themselves and their future but they may not take that advice.

Your sister is very comfortably off you've said and does not get on with your parents so on what planet does she think she would get handouts?

Your brother is in debt and has mh issues. Your parents are supporting the dc who needs it. Might not seem fair bit life often isn't.

At the end of life, money doesn't mean anything, but the relationships do. Don't let money get in the way. Your parents are trying to help in the way they think they are able to. As an adult, best you can do is accept it and move on. There may be uncomfortable feelings but there's nothing to problem-solve, let them be, accept and move on.

What inheritance? Who died?

The OP and her sister have helped their parents before.

Now they see their feckless brother engineering a plan that saves his bacon and her parents have once again bought into it.

Of course the OP is irritated by this.

History has shown her that when things go tits up, she and her sister may be prevailed upon to intervene again, when her parents may be homeless because of their brothers poor decision making.

Too right she has reason to be unhappy, not just because of the unequal distribution of her parents assets, but of the potential for a huge future headache which they may end up feeling obliged to fix.

I'd be more worried about the fact brother has done it once and will probably get in to debt again. I'd be making it clear that if it all goes tits up they could become homeless and you will not be bailing them out. I'd also be very upset if my parents gave all the money to one child. I'd be telling them this is your choice but don't expect me to be around for you in years to come. As you clearly care about one child more than the other. Just because I haven't made stupid life decisions and got myself in to debt doesn't mean he deserves this more than me.

If the brother and his wife have to care for his parents it may stop them having even more offspring they can't afford. It also absolves the sisters from getting involved in their care too.

I doubt the OP is planning any wad chucking herself. She just wants a wad chucked at her instead of her brother.

l would be very glad that they are taking on the care of your parents tbh. After having retired early to look after my Parents . My Mum is now in a home after5 years of us caring for her, completely her decision , which she is paying for and l am glad she is happy and l don't care about the money because it was never mine in the first place . You won't have to do a thing OP and that is so freeing, worth far more than money .

I would be worried about my parents putting themselves in such a vulnerable situation.
They could end up homeless and penniless.

Another person who finds “it’s their money, it’s their choice” mantra annoying. It’s very cold and unfeeling to the other siblings who have been ignored.

However, in this case though, your parents are getting something for it in return it looks like? Or at least are expecting it? £40,000 is not a huge amount and you and especially DS are reasonably comfortable. I’d stay completely out of it and their choices and especially the consequences of those choices.l down the road. Maybe thank your lucky stars you are not involved in such an arrangement even (and it might work out for them who knows).

I don’t blame you for being browned off OP. I don’t think it’s ‘grabby’ to expect inheritances to be divided largely equally between adult children - and maybe Gdcs, if there’s enough.

TBH people who run up a lot of debt maybe well be hopeless with money (I know this won’t always apply by any means) and will all too likely only do it again - especially if they suddenly feel ‘flush’ again.

The fact that people are legally entitled to do whatever they want with their own assets is beside the point - to me, anyway. I know my parents and ILs would never have dreamt of unequal shares, let alone leaving anyone out.

I always find these interesting as the 'other' children do not take into account their parent/s are getting something for the 'inheritance' they are 'giving' away. Accommodation, company, support, companionship, peace of mind etc. I am guessing this 'purchase' is something they are happy with and its their money and their final stages of life. They don't owe you and your sister 'inheritance'.

Until father needs full time care, there’s no money left to fund it and the LA want to know where the money’s gone, because now they’re being asked to pay. From there it gets messy. Not to mention what happens if brother gets into more debt and makes them all homeless, or SiL decides she can’t cope with care needs.

You're absolutely right that it's easier said than done. But as this brother sounds like a bit of a disaster, and nothing OP has said suggests she's going to be able to prevent this from happening, it may simply be a situation where all she can do is work on her boundaries and start planning her excuses for not helping now.

I don't expect any inheritance. I don't need it financially and have told my parents many times they should spend everything while they can and enjoy themselves.
But if they left everything to my sibling and nothing to me I would be devastated. Not because I want or need the money, but because it would be obvious they cared more about them than me.

Lots of people on this thread seem lucky enough to not have “that sibling” or know some like that. Who lives being bailed out, who next plan is the big one. This is nothing more than a good idea without the realisation of exactly what they are signing up for. It also doesn’t take long for the elderly parents to become resentful at the reality of sharing your home. They are in debt without the looking after elderly parents. As for it not being the OPs problem if it goes wrong, that is so easier said than done. “Told you so” doesn’t really help when left picking up the pieces.

Of course it is very hurtful but you will have to accept it.

In your place I would drop your parents a letter, advising them to get legal advice as there are pitfalls including future homelessness, if things go wrong for them.
Keep a copy of it.

Giving everything to the favoured son is a very familiar story that I have come across over the years, be it the farm or a valuable house on a large plot.

It has NEVER ended well for the parents.

Their daughters stepped away and there was huge bad feeling.

In one case the son sold up after years of free childcare and moved far away.
His sisters never forgave their parents and have remained estranged to this day.

The other case that comes to mind was a sister who was promised a site on the farm her brother was gifted in its entirety, only to be asked for money for it.
She moved 30 minutes away and her parents were deprived of any meaningful involvement in their ONLY grandchildrens lives.

It is about so much more than money, it is about fairness.

I find posters calling the OP's in this situation grabby, extremely obtuse.

To effectively be disinherited by your parents, in favour of a sibling is painful, irrespective of the amount involved.

Your parents are likely to deeply regret their trusting your brother to do the right thing long term.

I would not have my in laws move in and live in my house permanently for a million pounds nevermind £40,000. Your sibling and his wife are doing your parents a huge favour. You are not at a disadvantage here.

Your parents need to get legal advice and protect whatever sum they put into your brother and DIL house. But other than that I’d leave them to it but I’d certainly not be bailing anyone out of any future financial mess

Obviously you are being “cut out of their will” for want of a better phrase, basically they have all but disowned you imho
Oh, get a bloody grip 🤣
