It has been my intention to await my ILR this November and then proceed with a divorce
If you proceed down that route, do be aware that you, and also possibly your wife, would be committing a criminal act, on signing the declaration on the form SET(M), effectively certifying that there is an intention for the two of you to stay together.
Your declaration on the form SET(M) includes :-
I hereby apply for indefinite leave to remain in the UK for myself and any dependent children listed in this form on the basis of my marriage to ......... the person who has signed the declaration below. I declare that we are still married, that we are living together as husband and wife and intend to do so permanently, .......... . The information I have given in this form is complete and is true to the best of my knowledge.
-: and it goes on to mention :-
I am aware that it is an offence under the Immigration Act 1971, as amended by the Immigration and Asylum Act 1999 and the Nationality, Immigration and Asylum Act 2002, to make to a person acting in execution of any of those Acts a statement or representation which I know to be false or do not believe to be true, or to obtain or to seek to obtain leave to remain in the UK by means which include deception.
-: and given that you have already mentioned the D word, you cannot possibly sign that declaration, can you!
But if you have a Court Order, or agreement, giving you access to your child, then indeed it is possible to get a visa on that basis.
