Decided to cut all money from W . When she contacts me about it im going to say 1. it was her decision to live this way and i will no longer be helping finance her new life. 2. D will get a bank card for anything she needs. As much as i want to mention her moving on with someone else i wont!!
Let's set aside the wisdom of your approach from a DB perspective and focus on the legal perspective. It isn't a good move from a legal perspective. You are always better off telling someone in advance if you are going to make a drastic change like that. If you don't, you'll come across to the court as manipulative and cruel. In addition, if you make more money than she does by a significant measure, then you'll owe support for some period of time. Best get an idea of what that amount is and give your W access to that amount of money. Where people hurt themselves legally is when they give their spouse more money than they are legally required to give and it ends up setting a precedent for the future.
