My grandmother, when living in NJ years ago, had an attorney draft a will. She died a year ago in China. Almost all her assets are in China. The named executor lives in China. She had one son and three daughters, all of whom except one daughter lives in the NY/NJ area. The will is very ambigously worded. The son claims that he is to receive almost all of the assets, while an alternative interpretation gives him just 25%. He has refused to even sit down to discuss the matter. What legal actions can be taken in the US, e.g. will construction, a declaration whether the English or the Chinese version of the will controls?
