UK/Germany tax rights: mother's UK estate in administration / German tax-resident

My UK-based mother's estate is in the administration period. Since her death, it generates income via UK rental properties, UK interest-generating bank accounts, and a few interest-generating foreign accounts. I, one of two beneficiaries, am tax-resident in Germany. The estate accountant believes ALL income is taxable in the UK - the 'estate' rather than myself/sibling being taxed. But my German tax adviser believes 50% of all bank account interest is taxable in Germany only, as my personal income. And that rental income is taxable in the UK, but 50% can be cited to raise my German personal income tax rate even as 'estate' income. They cite the UK-Germany DTA rules as grounds. I can't find a UK tax adviser who can agree with or disprove the German adviser's argument. Can anyone advise, so we avoid mistakes with estate and personal tax returns - thank you very much.

Hi, 
 

As the income is arising in the period of administration, the estate will be liable for the inome that is generated : Dealing with the estate of someone who's died . Thank you .
