Sibling Not Included In Will

No, but they can voluntarily gift you any amount they choose.

 

Depends on how much they give you. Anything over $16,000 (per donor) needs to be reported, but there is no tax do until they hit the $12 million lifetime gift exemption.

There are a few times when omitted children can get a share of the estate, but it is very narrow. Essentially, you have to have been born after the will was executed and such future children are not specifically disinherited.

 

No, but they can all give you a share of what they receive.

 

I'd ask a probate attorney in the state where the probate is taking place. Some states do allow such changes if all beneficiaries agree to it and all are of them are competent adults. For example, NJ has a statute that expressly allows such changes. In what state is the probate taking place?
