I live in NY State, my inlaws have not spoken to us in 2 1/2 years.. Out of evil motives against my husband and I they have discontinued sending checks to our children for their birthdays and now purchase E bonds. Previously to having them stop talking to us. We told them to please not purchase bonds, that we have College 529 plans for them. Due to the maturity length of time, my children would not be able to utilize these bonds until they are 30 years of age. This does not help them with anything. The in laws also have the bonds sent to their homes we are not in possession of any of them. US treasury has confirmed this. I do not want them using my children's names & social security numbers for paperwork they are responsible for when they no longer speak to us. Identity theft is rising in childrens socials being stolen. How do I prevent them from continuing to do this. They are very spiteful people.
