Confusing Child of sponsor Evidence - 1st LTR Extension

Good morning everyone,

I am a bit confused over some evidence which has been asked for this time round. First some background information. We have just paid for my wife and step son's 1st Leave to remain (they are Belarusian), after there initial leave to enter. We have paid and submitted for the visa's and IHS. We also have our appointment booked for the 27th of this month (November) for the Biometrics and to have our documents scanned.

Questions are regarding my daughter. I am the sponsor and a British citizen, my daughter from a previous partner is also British. Whilst she was mentioned on the first leave to enter, they have asked a lot more of her this time round, and I am failing to understand why. Two pieces of evidence are stated to be provided in our document checklist which I am scratching my head, about as I really don't understand the relevance.

1. Evidence of Applicants (wife) parental responsibility with my (Sponsors) daughter, such as birth or adoption certificate, proof of financial contribution to the child's well being or general evidence demonstration concerns and interests of the child.

While I will provide my daughters birth certificate, this reads more as if my wife has adopted my British daughter, or is somehow responsible for her, which I fail to see how this is the case? She does not have parental responsibility for my daughter, nor any financial contribution. Those are both on myself as a father, and my ex partner. Relationship with my ex is amicable, no child arrangements or court orders exist.

2. Evidence of Applicants (wife) access to my (Sponsors) British daughter, such as a written agreement between both parents or a child arrangement order.

Again, I am baffled by this statement. My wife does not need access. It is myself who is responsible for her, nothing to do with this visa as I can understand. I do not see why I would need a written agreement from my ex and myself to state something which doesn't exist. If there was a child or court order in place then yes I could understand. But with myself having a 50/50 responsibility with my daughter, it would be me who needed this if the need arose, not my wife (applicant). I do not understand why I need to write and sign along with my ex to say something which makes no sense legally or otherwise?

Hoping someone can make some sense of these for me, as its left both myself and wife completely confused. Whilst I can easily provide a written statement, I simply don't understand the requirements as part of this visa.

Thanks in advance, Craig.....

They claim the online form is interactive but it isn't. It's very generic and tends to leave applicants confused.

Make the points in a covering letter that your wife doesn't have those responsibilities for your daughter and that should suffice.

Thanks Korekt for your response.
