Requests for 'checklists' are a regular subject here.
To be honest, it can be both timeconsuming and tricky to really get to grips with what's important and relevant for your application and what isn't going to add benefit to the application.
One of the problems with 'checklists' is that they can cause undue stress if you don't have everything that's listed or if you want to include something and it isn't listed.
The applicant and sponsor need to discuss and agree just what they feel is right for them and their circumstances.
It's hard to make informed judgements when your life is being put into an application form and a bundle of supporting documentary evidence.
The tendency is to include everything just in case.
Consulting a 'one-size-fits-all' checklist and just ticking the boxes for each document doesn't cut it though.
It's not the document itself that's important, rather it's what the document says.
In principle your application is personal to you. The supporting evidential documents that are important to you may not be at all relevant or appropriate
for others.
Ideally a checklist should be used as a simple guide to help bring ideas and clarity for the applicants personal document list.
As UKVI statesThe best starting point in developing your own document list is to review the UKVI webpage indicating Documents you need to provideThe submission of all or any of these documents does not guarantee that your application will be successful.
Include documents to prove that you meet the eligibility requirements - read the guide to supporting documents for examples.
