UK inheritance: partner, sibling, child Let's start with person A. Person A wants to write a will leaving "everything" to their partner, person B. They are not married, or in a legal partnership of any kind. Person A would prefer that their only sibling inherit nothing. And that a child born out of wedlock, but acknowledged on their birth certificate (foreign, but not UK) , living overseas, receives a share, despite the will, as a gesture, stating that person B inherit "everything". Given the will, does person A's sibling have any claim? Their child?
The child C cannot receive anything as a "gesture despite the Will" if everything in the Will is left to B; unless B agrees to a Deed of Variation the Executor is legally bound to follow the instructions in the Will. C may have a claim if he is dependent on A at the time of A's death and A has failed to make provision. It is possible that A's sibling S might also have a claim if dependent. Although you have tagged the question as United Kingdom, inheritance and intestacy law differs widely between England and Scotland. Such a Will should be drafted by a specialist trust and executry planning solicitor to avoid the risk of contentious probate.
These types of situations can, do and will get very messy and bitter fast. The key question here is actually two basic areas: What’s the legal situation now in terms of what you can actually claim etc? For this you need a lawyer familiar with the local laws. Second, and much more important, is how much you value your relationship with your sister. These types of situations can and do irreparably break families, and you need to think very hard about this element of the situation regardless of what your legal rights are. Personally I would err towards probing gently into what she thinks is fair/your mother intended etc and go from there, with the emphasis on extreme caution. Money can always be replaced. Families can’t.
Issue in this sense means a person's children or other lineal descendants such as grandchildren and great-grandchildren. It does not mean all heirs, but only the direct bloodline.
united-kingdom To extend on @ohwilleke's answer about US inheritance tax, I can answer the UK side of things. UK inheritance tax does not apply to inheritances from abroad, unless that person was domiciled in the UK or some of their assets were in the UK. If you are not a UK resident for tax purposes (which, from the context of your question is unlikely), then you wouldn't even have to pay tax on the interest you earned from depositing the inheritance. If the deceased were taxed for being domiciled in the UK, and the US taxed your inheritance, you'd actually qualify for tax relief from HMRC based on what you'd already paid the IRS. If you are not domiciled in the UK for tax purposes, and neither was the decedent you would owe precisely zero to HMRC in the UK.

Would capital gains taxes come into play given that the house is his daughters primary residence, but not his? Yes. He sold something that was his property, i.e., his [long term] asset. The fact that it was not his primary residence is irrelevant in this regard. The issue of primary vs. non-primary residence might be relevant only for purposes of computing the applicable credits and/or deductions, but that is very jurisdiction-specific.
If you buy a house and your wife signs a quitclaim deed to you, that transfers to you whatever rights she has in the house. Similarly, if you and your wife sign an agreement that anything deposited in a particular bank account in your name would be your separate property, that would override the pre-nup as far as that account was concerned. Such an agreement could include a dollar limit per month or per year, or an explicit purpose, such as savings for a down payment. (It could be thought of as a gift to you of her share of any funds deposited.) Giving property to your parents or others with the understanding that it will be returned on your request might be seen as an attempt to evade the pre-nup, and a court might hold that the property was actually shared, if you ever do divorce. There might also be gift tax issues if the value is high enough. Whether asking your wife to agree to a quitclaim or any sort of agreement to modify the pre-nup would help or harm your marriage I cannot know, nor did you ask that. But I would think that for most people being open would work better than going behind a spouse's back. None of this should be taken as legal advice. I am not a lawyer.
I was told that when you sign something in the UK, then it is your signature, no matter what name you are using. So if you sign a contract with my name, then it's your signature and you are bound by the contract. Things might be invalid because you signed and not me. For example, if you sign a contract selling my car in my name, then that contract is not valid. If some document needs signatures of two witnesses, and you sign with your name, then with my name, then there are no two signatures. As far as I know, signing under a false name is not in itself criminal, but might very well be supporting fraud, for example, and might therefore be illegal. The contract for the sale of my car, signed by you using my name, would very likely be part of fraud and therefore criminal.
She never said that She said: When I joined that family, that was the last time, until we came here, that I saw my passport, my driver's licence, my keys. All that gets turned over With respect to my adult children and their passports, the same is true in my house. I ask them for their passports when they aren’t needed, they give them to me, I store them in a safe place and I give them back to them when they need them. That’s just a sensible precaution against them being lost and in no way illegal. Now if I took their passports without permission and withheld them when they wanted them, that would be illegal as it would for anyone else including the Queen (who, I’m sure, had absolutely nothing to do with it - that’s the job of the Keeper of the Royal Passports or some such). Similarly, if you came to my house and I offered to take your coat and you gave it to me and I gave it back when you left, that would be perfectly legal. When I pull up in my car, I put my keys in a bowl in the laundry (unless I forget and then I can’t find them and it’s really annoying). I would prefer instead to have an employee jump into the car, park it and put the keys in their bowl so that when I want the car latter, it’s their job to remember where they left the keys. But I can’t afford that.
