Thanks for your reply.
The issue that you have is that parents are only permitted as dependent if you can show that they are financially dependent on you. A person is financially dependent if they rely on them in order to live, essentially meaning that without the assistance that you provide to them they would be living in poverty.
If this is the case then you need to demonstrate to the immigration tribunal on appeal that your mother does not have any assets or income and would therefore not be able to support or accommodate herself in her home country. She will need to execute a sworn statement swearing that she does not have any assets or income which she could avail herself of in order to live. She needs to say that the assistance you provide her in the form of housing and food is the only way that she is able to live.
Both you and your spouses need to corroborate this in statements and confirm that you will continue to provide the assistance she needs.
You need to evidence all of this, bank statements, sworn statements, Land registry official copies showing your ownership of your property, a budget showing that you can afford to provide this assistance.
In short, if you are to appeal you need to instruct a UK immigration solicitor to prepare your trial bundle and supporting documentation. They will then instruct a barrister (counsel) to argue your case on the day. This is the way that you give her the best possible chance of success.
