如果先办理了选择1,还可以以后再办理选择2吗?
Yes, you just need to record new deed. Again, if both are US citizen, there would be no gift tax consequence. Otherwise, please consult an accountant.
请问上述的两个选择是不是都可以避免Probabte?
yes, for the most part, unless heir may challenge the second arragement if it happens while the donor is mentally competent.
两者在避税上有没有区别?
No. Neither affords you any tax benefit, if you are both US citizens. If one or both are not US citizens, the second arragement is preferred. However, gift tax is always a concern as I mentioned above
各自的利弊是什么?
It's too complicated to tell here because estate planning is not only a legal or tax issue. Many time it is a family issue. Without sitting down with you understanding your family situation and needs, no competent lawyer should give you any advise on how you should do it.
非常感谢!
