It may be helpful if you were aware of the UK tax language used for your situation.
You and separately your husband will become UK resident during the 2019/20 tax year. You are each seeking to use the split year rules for 2019/20. You should consider any past periods of UK residence and days in the UK to check that you are able to qualify under these rules.
The good news is that you would get the benefit of a full personal allowance and the rates of tax against income for three months. So you should be lightly taxed in the UK. Please be aware if you are going to be employees that the PAYE system may overtax you, and you might be later entitled to a refund.
