Thank you for the explanation. Actually we were in a chat, and when we were in the chat you could have refined your question before rating me. Customers often do that. However, once you rated me, the chat was over and now you will have to rate me as you go along.
Your new question is “Would being adopted in France impose on my step-children any obligations, responsibilities or charges vis-a-vis the French state which they did not have before? “
To address pertinently, informatively and accurately your new question, I am assuming that you know and fulfill all the requirements of a French “simple adoption.”
Being adopted in France as a “simple adoption” imposes on your adult step-children (UK nationals) very few obligations and responsibilities vis-a-vis the French state. However as for the end part of your question (“which they did not have before”), I do not know what obligations they had before, so I can not say if these obligations vis-a-vis the French state are different from before.
The few obligations or responsibilities your adult UK national step children will have directly vis-a-vis the French state will be filing the French inheritance (estate/succession) tax documents and paying French inheritance taxes (or French late filing tax penalties) and your debts if applicable (including funeral services) or filing a formal refusal of the French inheritance (estate/succession) after your death. That’s just about all. Apart from what I just mentioned, your step children really have nothing to worry about. The French “simple adoption” is basically only about inheritance. That’s all.
