Just wondering really. I'm currently getting divorced, our financial settlement states that we will have no future claim on each other's finances. No parents, NC with my only sibling. I don't want STBXH or my sibling to get my estate after I die. But I don't really have anyone else that I am close to that I would want to benefit. What happens in cases like this? Will everything go to my sibling as my only blood relative even if I haven't specifically left things to her? If I did make a will how would anyone know?
There are strict intestacy rules. Government webpage here It's crazy that there isn't a Register of Wills but solicitors often phone around an area, asking fellow solicitors if they hold a will for recently deceased parties, so they do try to track it down.
Shameless plug here, but there's a Will Writer on here called Mumblechum. She's got an ad in the Small Business Ads section )not sure what it's officially called) 'cause she's doing a special offer on Wills for MNers.
Find a reputable solicitor, appoint them as executors and store the will with them, so it will get dealt with then, though they bill your estate. Then leave to charities or deserving people you know. Otherwise yes will go to your siblings equally.
Siblings wouldn't realistically be able to challenge unless you were supporting them.
OP, it would be very straight forward for you to make a will leaving your estate to your preferred charities, and if you decided to come to me I'd also ensure that a clause was inserted to say that, if those particular charities didn't exist at your death, your Trustees would pay those gifts to other charities with the same aims and objectives.
Gifts to charities are exempt from Inheritance Tax by the way.
It is sometimes appropriate to give a small lump sum to someone who may otherwise be minded to have a go at making a claim, however the OP's sibling wouldn't have a "reasonable expectation of provision" in my view and certainly isn't dependent on her so I wouldn't advise giving her anything.
