At first glance your list looks good but I do not think an emailed bank statement will be acceptable. I am sure if I am wrong, someone will correct me.
The bank statement won't be emailed, it will be AIRmailed - so it won't be a problem. The only issue may be that it gets lost in the post or something, so if possible, it should be sent by overnight courier like FedEx or UPS to guarantee safe and fast delivery.
A Land Registry document confirms ownership so is necessary but it will not confirm that there would be no overcrowding. You would need a property inspection report for that.
Yes, the Land Registry document only states who owns the property and has nothing to do with overcrowding.
However, a property inspection report is not required for the visa and has never been required.
All you need to do to show that there won't be overcrowding is to have the letter from the family member state the number of rooms in the house and number of people living there, to show that there are enough rooms available.
Lastly, yes, you still have show that the relationship is genuine! I have been married for 47 years and still sent some photos, correspondence in both names along with the marriage certificate.
It's not so important to show this for a relationship where the couple has been married and living together outside the UK.
You just need the marriage certificate, maybe 1 or 2 photos of you together, and if you like you can include some evidence that you live together.
On some settlement visa applications, the applicant is asked for employment details. If the applicant is working, then evidence should be submitted to support information given on the application form.
Not true. The applicant's income has no bearing on the application and no evidence needs to be provided. It will not be considered as part of the application and may not even be looked at.
If the application asks for applicant's employment (and I'm not sure that it does), then you can give details on the application form, but no evidence needs to be sent.
Don't forget that for the application, you need to fill out two forms - the online application form (
https://www.visa4uk.fco.gov.uk/), which just asks general information about the applicant and then the VAF4a Appendix 2 form (second link down here:
https://www.gov.uk/government/publications/application-for-uk-visa-for-family-settlement-form-vaf4a), which you need to print and fill out by hand, and includes all the information about your relationship, your financial requirement and your accommodation.
