I will endeavour to help with your question.
The straightforward answer is yes, but this will become a "settlor-interested" trust and put you into a penal tax regime. It will potentially have disadvantages for income tax and IHT.
Does the trust just have money in it or does it hold property?
IHT isn't a problem, I want to give my Partner an income when I die and then on her death the capital reverts to my children.
